Precision Lifts

This is the first version of Precision Lifts, an app designed to make it easy to track rest times and record sets during your workouts.
If you're an experienced lifter, you probably know the importance of tracking rest intervals between sets.
In most strength training routines, you want to be keeping rest intervals consistent while increasing some training variable (usually reps or weight) with each session.
That way, when you lift more than you did last workout, you know it's because you got stronger and not because you took longer rest intervals than usual.
The problem is that it's hard to do this, especially if you're lifting alone.
I got tired of manually timing my rest intervals and recording sets with each workout, so I built an app to help.
Although accurately tracking rest times is the primary focus of Precision Lifts, that's not all that it offers.
Other features include:
-Custom reusable workout templates
-Email export of workout results (text and .csv files)
-Workout history detailing all sets, reps, weight and completion times of past workouts
Features coming soon:
-Graphs of volume and weight progression over time for each exercise
-1RM calculator
There's a chance I may add premium features or advertisements in the future but at the time being Precision Lifts is completely free to use!
The only thing I'd ask if you use this app is to please let me know if you have any comments or suggestions.
