WHAT USERS ARE SAYING
"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!" - rugoody
"Amazing to not have to pay thousands for a unit or even attach anything to a bar. Just click record on your camera and I can track my athletes Bar Velocity so easily." - Giannire
"For not needing to buy any equipment this is a great tool. The vbt trackers go from 400 and up so for this to do what it does with nothing is amazing." - NoelpereziPhone6P
"The app is brilliant. Superb for checking/tracking form and progression at the same time. I took an annual sub out after 5 days" - far.landscape

I really wanted to give this app five stars because I loved everything about it, except for the apps inability to recognize reps. Time after time, no matter where I put the camera, it didn’t record reps and thus didn’t give me any output for them. Because of that I won’t be going on to use the pro version, but otherwise this app was pretty useful.
Developer Response
Agh, Jason, we were so close!!! Thank you for the review, and your honest feedback. We really want to keep improving and maybe there is a bug or an issue we can fix that will solve this issue. If you could, maybe send me through some example videos that had failed to track your reps? We can take a look at these to see if we can keep getting better and improve the tracking reliability. I'd love you to be able to get good use out of the app in your training. - Looking forward to hearing back Jacob. You can contact me at jacob@metric.coach
Great app, getting better

I love this app! I don’t usually write reviews, but this one deserves it.I I have the paid version of this app. I’m not compensated for this review. I use this app on an iPhone 15.I’m 60 years old and I’ve been lifting since I was 16. Being older, it’s definitely more difficult to gauge the quality of workouts. Both strenuous workout is while you’re doing it, and how much time you need to recover afterward. This app helps with both. it helps during a workout because I can see how fast I’m moving the bar, so whether it’s a strength/power workout or a speed workout, I can tell when I’m getting tired or the weight is too heavy and adjust from there. Similarly, if I do the opposite work out the next day (if yesterday was a power workout, then today is a speed workout with lighter weight, but moving the bar much faster) I can see how much weight I should use today. You can set auditory prompts to let you know if you are hitting your velocity goal, and then you can see all your data immediately after each set. It also keeps track of your personal records and it is very motivating to see during each workout that you move the bar faster on a certain weight for this workout than you did for the last workout. Even though it is the same weight,you may have moved it faster. In that just helps keep your motivation up because otherwise you can feel like you’re not making any progress. Jacob and his team are very responsive questions and suggestions. Awesome app, awesome developer.

Thank you so much Davey, glad you are liking the app!!
Enjoyed using the app

It works pretty well, but it would be nice if they could integrate the Apple Watch and LiDAR that are part of the iPhone Pro line. The Apple Watch is a point of contact with a built-in accelerometer, which is closer to the bar and the LiDAR to get actual distance and more accurate reading of velocity with the camera. The app does an okay job, but the measurements are a bit off. The integration of allowing coaches to see their athletes' data is incredible, but with other devices, it is Standard practice. I can put a device that attaches to the barbell for 500 dollars, comes with a companion app, and it’s way more accurate. The downside of those devices is that they require an iPad and a mat for the laser to reflect on. I also can’t have the athlete use it at their will. They need to either own the device or have it on hand, But if you think about it, an iPhone Pro 12 can be found for less than that and an Apple Watch. There are over devices that run a couple of grand that, again, if you think about it, between your newest watch and iPhone, you're already in about that price point. It’s a great concept I hope they can expand on the accuracy and use available hardware instead of focusing on stop gap measures like giving me a notification that “I’m improving”.

Hi Jbarah,We have actually been recently externally validated against MOCAP and found to perform really well for accuracy.We have considered using the Apple Watch and like the idea of LIDAR also, but in our research into incorporating these technologies found they did not improve accuracy at all. In fact, the apple watch was a major step backwards from computer vision - delivering very erratic and inconsistent results. Something that is a known issue with other VBT hardware devices and wearables that have utilised accelerometer data - it is just too inconsistent.
Questioning The Accuracy of Measured Velocity
xelanart
It seems a bit inconsistent from where the timer starts for the movement and stops for the movement, across different sets of the same exercise. On one occasion, it had been way off in tracking the bar path, evidenced by the line it displayed that went in the complete opposite of the bar path. Additionally, some times don’t logically match with the load/intensity I used (i.e. set 1 of 405 lbs deadlift measured 0.55 m/s while set 2 of 455 lbs measured 0.52 m/s while set 3 of 405 lbs measured 0.57 m/s, with standardized rest times). The concept of the app is great, but I don’t feel like I can trust the measured data.
Developer Response
Hey xelanart,Agh, a few people reported this quirky bar path issue a couple of weeks ago, we should have hopefully pushed a fix for that with v4.3 & another that tightened up eccentric tracking with v4.4.If it happens again do you think you could send us some sample videos of this weird bar path you are seeing? We are always hungry to improve the tracking algorithm, and bug report cases like these are really helpful at exposing weaknesses and limitations in the app!In terms of the velocity differentials these numbers are very normal and that level of variation would be fairly typical no matter the tech you use to track velocity.Every set will have its variations in technique, velocity and ROM, a spread of 0.52-0.57 for these 405 lbs deadlifts sounds like a pretty typical workout! Happy for you to send me the videos for these and I can explore further if you think the numbers are wrong though!A spread from 0.5 - 0.65 would be concerning, but all sets between 0.05m/s is Metric doing a great job of delivering reliable data!Jacob
