Version 1.3 - Tempo and set review customization
What's New 🚨
Eccentric tempo tracking
Metric now tracks and reports your eccentric tempo for each rep. Tempo tracking is a great way to keep yourself honest and train for better control on the descent.
Customize your highlights cards
You can now pick your preferred display settings, choosing which metrics and highlights get shown on the training dashboard. You can tune Metric to better support your goals.
Bodyweight recording
You can now keep track of your bodyweight on your profile. This feature doesn’t do much (for now) but very soon Metric will leverage this data for calculating more advanced scores like relative strength and power.
Improvements ✨
- Algorithm improvements. Metric has been improved with better handling of unilateral and Olympic lifts.
Fixes 🐛
- Inevitable bug fixes. Another release, another slew of bugs crushed and general usability improvements help Metric be faster and more reliable than ever!
Version 1.2 - Bar chart mods, algo fix, snatches
What's New 🚨
Snatch velocity tracking
Metric now supports tracking for Snatch variations. Be sure to place your phone in a position that allows for the entire lift to fit in the frame.
Bug report button
Users now have a direct line to the Metric development team so they can report issues, share glitchy videos and request features.
Improvements ✨
- Compact bar charts on the home page. The Metric UI is now cleaner, with the bar chart getting far easier to access.
- Stability improvement to filter false repetitions. Thanks to your feedback we were able to find a bug causing false rep detections when phones were in certain positions. This should now be much more reliable.
Fixes 🐛
- Moved some pixels around to keep Metric looking slick and easy to use.
- Improved the login, sign-in and forgot password flow, including a bug fix for keychain access.
Version 1.1 - Context, zoom, custom plate size
What's New 🚨
Training context
Metric now provides simple training context information that helps you determine how well you are lifting. The difference between the current set and the last set you performed of the same exercise at the same weight is shown below each stat on the homepage.
Camera zoom capability
Users setting up in tight spaces rejoice! You can now pinch to zoom. If your phone features a wide angle lens you can now use that extra space too.
Custom plate sizes
Now it is possible to train with those odd sized plates floating around your gym. When entering the set exercise information add the diameter of the largest plate on the bar and Metric can deliver accurate data.
Improvements ✨
- Less invasive alerts in camera setup. Metric will still alert you when stabilisation issues are detected, but will be a bit calmer This makes it easier to play with the new Zoom feature and not feel you are being yelled at by a computer!
Fixes 🐛
- A bug that caused noisy reps for some users has been tracked and fixed.
- A laundry-list of housekeeping and pixel pushing was also achieved.
Version 1.0.1 - Ballistic lifts and intelligent rep detection
What's New 🚨
Major algorithm upgrade
Metric has thrown out the rulebook (again 😀) by using an all-new intelligent rep feature classifier that determines your actual rep start and end points. With this smart algorithm update your rep velocity and ROM data is more truthful and actionable than ever before, and Metric can now easily handle ballistic lifts.
Ballistic lifts added
Several new lifts have been added to the exercise list including: loaded jumps (trap bar and barbell), cleans, jerks, push-press, high-pulls and step-ups. This is made possible thanks to the new rep feature classifier algorithm.
Support for multi-athlete recording
Early access users of Metric for Teams can now quickly switch between athletes while using one device to record sets.
Support for deleting sets
For future planned capabilities we have now added the ability to delete a recorded set entirely. This can be handy if you are messing about showing someone how to use the app and don’t want their set saved in your training history (hint hint).
Improvements ✨
- Search field on the exercise selection screen. You can now quickly filter the list to find your lift.
- Fewer taps between sets. Metric previously had an extremely convenient workflow for adding a new set, but after hundreds of sets recorded we realised we could significantly reduce the taps required by condensing everything to a single screen prior to recording.
Fixes 🐛
- Accelerometer tweaks to reduce false set cut-offs. Metric was previously a little sensitive to the device being moved and would prematurely end sets. Dropping your deadlifts is now less likely to kill the set recording (thanks Bryce!)
- General bug squashing. As ever Metric has had a range of small bugs or crashes resolved.
Version 0.6.0 - Improved 3D tracking and correction
What's New 🚨
New exercises
Two new exercises added to the library - Step Ups and Floor Press.
Improvements ✨
- Overhauled the tracking algorithm. Metric is now able to record sets reliably from a wider range of phone positions, including placing the phone lower down relative to the barbell.
- X & Z axis correction. Metric now features X-axis and Z-axis correction so mean velocity is more accurate, and aligns with other velocity tracking technologies that also offer X-axis correction.
Fixes 🐛
- Touch ups and bug squashing. As usual stability has been tweaked, bugs and crashes should be less common as a result.
Version 0.5.4 - Set editing and rep removal
What's New 🚨
Editing set details and hiding reps
You can now change the exercise or weight after recording a set. Even better, Metric now allows you to exclude a rep from the results. Maybe you pulled the bar too hard on set-up? No problem, press the icon next the detected rep to remove it.
Improvements ✨
- Variance is now consistency. Previously Metric reported how varied your range of motion was each set. Now Metric displays how consistent - the inverse number. Basically you should aim for 100% consistency!
- Optimisations for older phones. Users with older devices (especially on iOS 14), were sometimes getting some funky results. Metric is now better optimised for these devices and should be more reliable for these users.
- Memory handling restructure. When video was being reprocessed for accuracy, sometimes results would be wildly inaccurate. The culprit was memory handling; Metric now handles memory properly so more accurate results are in fact more accurate.
Fixes 🐛
- Tiny pop-up is no longer. A micro-sized information box in the app would randomly show up after a set and force users to re-start. We hunted down a tiny error that caused the tiny pop up and it should no longer be a problem.
- Touch ups and bug squashing. As usual stability has been tweaked, bugs and crashes should be less common as a result.
Version 0.2.1 - Public Beta
Improved ✨
- Enhancement to the velocity detection algorithm.
The increase in fidelity with version 0.2.0 exposed a skew in Metric’s measurement of fast movements where bar speed exceeded ~0.8m/s mean velocity. This update removes this skew at faster velocity, further improving Metric’s validity and correlation to MOCAP reference data. Users may see notable change to their reported velocity for fast reps.
Fixes 🐛
- Fixed a selection of annoying crashes.
Metric pushes some older devices to the limit, often asking too much (of their memory and graphic processing). Metric is now less demanding, so older devices should no longer throw in the towel during sets!
Version 0.2.0 - Public Beta
Improved ✨
- MAJOR UPGRADE to the velocity detection algorithm.
Metric has been overhauled to enable high frame rate analysis at higher video resolution. This results in superior measurement fidelity and processing speed. Metric could previously process live video at 480p resolution at throttled frames per second. Significant re-writing of code now enables live video processing at HD 720p resolution and 60 frames per second. To say we are ecstatic about this update is an understatement! - Tweaking the movement triggers that end set recording.
Metric should end the set recording when you pick up your device, but not when you bump it or drop weights. The device accelerometer monitoring has been tuned to better distinguish events and this should prevent set recording from ending early. We expect the trigger algorithm will need further refinement but this version should be a big step in the right direction!
Fixes 🐛
- Fixed a selection of annoying crashes. Metric would spontaneously and dramatically stop in the middle of some users’ workouts. Now it should be more considerate and keep working for as long as you do.
- Made the results table display more reps. Some users (who apparently enjoy pain and discomfort) would do sets of more than 17 reps. Metric previously couldn’t scroll that far on the results table, but now displays as many rows as required to pinpoint the exact moment you lost the will to go on.
- Reduced media playback cut-outs. Your music or podcasts will cut-out at least 50% less often when starting sets. The other 50% is still unresolved but we continue to aim for perfection!
Version 0.1.4 - Public Beta
Improved ✨
- Update to the ROM measurement algorithm. Metric uses a velocity threshold to determine the starting point of each rep when calculating ROM. This could result in overly short ROM for very slow reps. Now the algorithm waits for the velocity threshold, but travels back in time to where the bar first moved. As a result, the Metric ROM calculation is now more accurate without counting false reps.
- Sticking-point recognition. When you hit a sticking point Metric would sometimes think you had actually reached the end of your rep. Now Metric believes in you, and will keep measuring the rep all the way to the top as you grind it out!
- Refined the device movement trigger for ending recordings. Metric stops recording when you pick up your phone. Previously the movement trigger was a little too sensitive, and vibrations from dropping weights could end your set too early. Metric should now recognise the difference between vibrations and you actually picking up your phone.
Fixes 🐛
- Fixed a bug that resulted in some users experiencing a crash while recording their sets. We were able to replicate the bug and Metric should now stay open and continue recording instead of just quietly giving up.
- Tidied up pixels that were not quite up to par with a few UI tweaks (thanks Andrew!) so the interface is now in a better place.
Version 0.1.3 - Public Beta
Fixes 🐛
- Fixed a bug where after selecting your weight Metric would correctly display the camera briefly, before incorrectly returning you back to the weight selection screen. This was due to a known problem with certain versions of iOS 14. Now instead of being refused entry to the future of VBT, Metric users on iOS 14 can actually experience it!
- Changed the app settings so it is no longer available on iPad. Truthfully Metric wasn't built for iPad, so users who installed it found everything was a bit off. One day soon we will make a version for iPad... but that is not today!
Version 0.1.2 - Public Beta
What's New 🚨
Movement warnings prior to recording
Because the device must be stationary to correctly measure velocity, Metric now features warnings when the phone is moved or not in a vertical position. This prevents you from recording sets before the camera is correctly positioned.
Picking up the device ends recording
To make it faster to end a set simply pick up your phone. Metric will automatically stop the recording when it detects movement.
Removed video upload feature
Now that in-app recording is working great, we no longer need the ability to upload footage from the camera roll for testing. This simplifies using the app, and also stops users uploading videos that have movement or the wrong camera settings, both of which were resulting in sub-par data.
Improvements ✨
- Velocity-time trace graph upgraded. Metric now shows a much better looking and more readable graph.
- Minor changes to text sizing and colours.
Fixes 🐛
- Fixed a text wrapping issue on some crucial pieces of information on several buttons and alerts. There's nothing worse than when a sentence just...
- Certain progress indicators were not being displayed at the right time. They now show up where they should, letting you know that Metric is processing your video rather than frozen!
Version 0.1.1 - Internal Beta
What's New 🚨
Set Summary Page
After your set you will now be directed straight to a set summary highlighting key numbers from your set like best rep velocity, velocity loss and ROM variance
Bar charts
We now have a rep-by-rep bar chart in the Set Review screen which helps if you are the visual type! It is excellent for understanding how performance changed over the course of your set.
Onboarding tutorial
The key instructions for using Metric are now in an illustrated onboarding when you open the app for the first time, and also available from a Help button on the Home Screen.
Improvements ✨
- Enhanced post-set workflow.
When you have finished reviewing a set you can now save it and immediately start your next set with the press of a single button.
Fixes 🐛
- Fixed landscape orientation killing the app. We have locked the app in Vertical orientation to prevent it becoming very not functional if you turned your phone on its side.
- In certain cases racking and un-racking the bar was being mis-categorised as a rep. The rep detection model should now properly ignore racking and un-racking!
Version 0.1.0 - Internal Beta
What's New 🚨
HD Video
Metric records sets in HD from either the rear or front-facing camera at 60 FPS. This means when you save the video to your camera roll it will be nice and crispy, just like your lifts.
Exercise and load picker
Prior to recording you can now select your exercise and weight. This information is then displayed on the Set Review screen so you can remember what you are looking at. If you screenshot your results this is quite helpful.
Improvements ✨
- Listen to music while recording your sets.
Previously when recording a set the video camera would take control of the audio, interrupting whatever you had playing. We wrestled the audio back under your control so you can keep smashing PRs to Tay Tay! - Less numbers on the review screen.
We have simplified the set analysis page to just highlight Mean Velocity and ROM. We also reduced decimal places to make the results table much easier on the eyes. - The rep and velocity detection model got better (again).
Uploaded videos process much faster, and missed reps should be few and far between now.
Fixes 🐛
- Fixed a strange flicker where dark-mode or light-mode switched for a moment when going from recording back to the app home screen. The flicker is no more.
- Fixed a crash which happened for some users on first installing the app. Metric was asking too many questions about your device when you opened it. It’s much more restrained now. Everything is on a need-to-know basis.
Version 0.2.0-beta - Stability fixes
What's new 🚨
No new features in this release — this update is focused entirely on stability and performance.
Improvements ✨
- Faster post-recording processing. Set data processes faster after you finish recording, getting you to your results sooner.
- Improved selfie cam tracking. Barbell detection on the front-facing camera is now more accurate and consistent.
Bug fixes 🐛
- Fixed numerous crashes during video import and processing
- Fixed a bug where users with a large set history couldn't open the app
- Fixed a crash in the velocity trace chart when reviewing longer video sets
- Fixed selfie cam data and bar path being inverted
- Fixed Google sign-up failing for some users
Version 0.1.0 - Processing speed ups, personal records and trend charts
What's new 🚨
Personal record badges
Every set now shows animated record badges for load, mean power, reps, and mean velocity — each displayed as a percentage of your all-time best. Tap any badge for a detail sheet with context on where you stand: new record, closing in, or building your baseline.
Velocity trends
A new trend card compares your current set velocity against your six-week historical average. See at a glance whether you're trending up (well recovered and ready to push, trending down (potentially fatigued or not lifting with intent), or holding steady, and tap through for a detailed chart breakdown. Learn more about how Metric calculates Trends here →
Set quality warnings
After each recording, Metric now analyses your setup and flags potential issues — viewing angle, framing, plate size, 0 rep reps, and device stability. These replace the old generic "no reps" message with specific, actionable feedback so you can fix issues and get better data on your next set.
Device stability detection
Your phone now needs to be stable before recording can begin. An on-screen status pill shows whether your device is ready, needs to be held steady, or stood upright. Recording is disabled until the device is stationary and automatically stops if significant movement is detected mid-set.
Fullscreen video playback
Video playback can now be expanded to full screen with a tap. Includes a time scrubber, mute toggle, and your bar path and stats overlay — all carried over seamlessly between the mini player and expanded view.
Intuitive video playback
Video thumbnails are now extracted from the first rep in your set to provide better context and video playback now starts playing from 1 second your first rep starts, making technique review more efficient.
Improvements ✨
- Set history improvements. More details are now included on your set history list including a video thumbnail, your best rep velocity and % fatigue in the set.
- Faster real-time processing. Frame rates during live recording have jumped from 30fps into the high 40s and low 50s on devices that support 60fps, meaning smoother tracking and fewer missed data points.
- Smarter weight formatting. Decimal loads like 72.5kg now display correctly across the app.
Bug fixes 🐛
- Fixed set data failing to load on some sessions
- Fixed an issue where Real-time recordings were dropping video frames during processing
- Fixed an issue with video imports and crashes on some Android chipsets and devices
Version 0.0.2 - 4k import & bar path fixes
What's new 🚨
Set highlight bar
The set review screen now shows your best rep, set average, and fatigue/consistency metrics right at the top. Key performance data for every set, all at a glance.
Improvements ✨
- Midpoint zoom for ultrawide cameras. Wide ultrawide lenses (0.5x, 0.6x) now snap to a tighter midpoint zoom (0.75x, 0.8x), making it easier to frame your setup without switching cameras.
- Persistent selfie cam settings. Your camera selection and zoom level now carry over between sets, so you're not re-adjusting every time you hit record.
- Faster video imports. All imported videos process significantly faster, with 1080p processing speeds up to 2x quicker than before.
Bug fixes 🐛
- Fixed a crash when importing 4K video
- Fixed bar path inversion on selfie cam recordings
- Fixed video rotation detection on imported videos on some Android devices that was causing zero reps or only detecting walkouts (XY axis inversion)
- Fixed a spacing issue on the record action button
- Improved recording controls layout
- Disabled uploading 480p videos, which don't have enough resolution for accurate barbell tracking
