The strength training app that sees your lifts.
A complete strength training app that measures every rep with your phone's camera. Track workouts, see bar speed, review your form — no wearables, no sensors, no setup.
Workout planner app
Log sets, reps, weight, RPE — or build a template once and run it every week. Workout history, progress charts, video review. The basics of a strength app, done well.

Barbell velocity tracking (VBT)
Point the camera and hit record. Bar speed, range of motion, bar path, and rep count — all measured automatically. No wearables, no sensor straps, no $500 hardware.

Strength and power performance analytics
Metric reads bar speed across your warm-up sets and translates it to today's estimated 1RM — no max-effort testing required. Pick today's working weight from today's data, not last month's PR.

Optimize your training with precision real-time tracking
Today's bar speed against your six-week baseline. Real-time feedback in your ear during the set. Stop when the bar slows, push when you have it.

Metric is built for coaches and teams, too.
Push templates to athletes' phones. Watch readiness across the squad. Review every working set without being on the gym floor. Coach Mode is included with a Coach plan.
Reviews for the Metric app
“Coaching both powerlifters and sport athletes, it's been hard to find tech that's reliable at very low and very high bar speeds. Metric is the first thing I've found that's truly designed BY coaches — average to peak velocity, velocity loss alerts, ROM, all there.”
“I'm 60 and I've lifted since I was 16. Being older it's harder to gauge workout quality and recovery. This app helps with both — I can see how fast I'm moving the bar and adjust load on the spot. The PRs are very motivating. Jacob and his team are very responsive.”
“Exactly the same functions as an expensive velocity tracker. Very professional.”
“Took an annual sub out after 5 days, no need to let the trial run out. Video is actually better than accelerometers because it gives you form analysis, not just power and bar path. Can't recommend it highly enough if you're at all interested in optimising your performance with barbell exercises.”
“This is what I needed exactly. It just has everything for me to measure my squat progress and this app made it so much easier — thank you so much to the developers.”
“Probably one of the best VBT trackers out there that doesn't require any additional equipment.”
“For not needing to buy any equipment this is a great tool. VBT trackers go from $400 and up, so for this to do what it does with nothing is amazing.”
“Super simple to download and just start using. Great for getting clients and athletes to engage with their training in new ways. Can't believe this hasn't been done sooner. Well done team.”
“Finally an app that works. Brilliant.”
“A really must-go for measuring VBT with extreme quality and precision.”
Measure every rep. No hardware required.
