Iron Path 4+

As the title says. I love this app for the bar path tracing.

I'm starting to use the graphs more to help work on my speed though. It would make it MUCH easier to see how the data correlates with the bar path and video of each lift if they were both displayed side by side (instead of toggling between the two).

Other than that though, great app!

Okay maybe I'm not using it properly (though it's hard to know since the online help link in the app returns a blank page so there are no available instructions on how to use the app as far as I could find) but when you try to set the path trace, in my case for squats, if you set the circle that tracks the bar on the end of the bar while it's racked, it doesn't follow the bar back when you lift it off the rack and step back to perform the movement. Zero traces. So then I tried setting the circle approximately where the bar will be after I've gotten into starting position. That doesn't really work either, I get a few partial bar path traces but only halfway or so through the movement's range of motion. The bottom of the movement I get nothing. It would make WAY more sense if one could scroll the video to the point where one is in the starting position, where it could be paused, and THEN set the bar trace circle. Again maybe it's operator error but the app doesn't seem to do what I expected. And I paid for the full functionality so I'm not too happy.

A barbel velocity tracker is about $500. I always wanted to start tracking velocity but I'm just a poor lifter. This thing is awesome. The fact that it tracks barbell path, force etc etc just adds to how much you can track and improve without counting solely on weight and reps.
I was skeptical that for $3 bucks you'd get all this info. I'm impressed.
I agree with the other review that the option of seeing multiple screens simultaneously would be nice but not a big deal. One other thing that I would like to see is the capability of sorting new videos on top and also creating folders to keep each lift separate but again. No big deal. These are minor options that are easy to add at some point. The important thing is the tracker and It works. Great job!
