The perfect 531 companion

After trying about a dozen solutions of the years, I finally discovered this app a month ago and it is by far the best, most efficient, and most intuitive app for 531 tracking. The design looks great and feels good to use. The in-app purchased are reasonably priced, which brought the total app cost to around $10 for me- which is well worth something of such elegant design. I have no complaints so far with it, perhaps maybe it’d be nice to have a few colorways that swap the red for other colors? But I’d be happy with its design for the rest of my life. Thank you for this app!

Incredibly functional app for 5/3/1

First time making a review because this app deserves 5 stars. I even bought the in app purchases just for extra convenience and to help the developer. I was using spreadsheets and print outs for a year for 5/3/1 and this app eliminated that. The ability to track all of your lifts over time with the calendar is by far the best feature. It’s great to easily look back at all of my lifts and notes for each day and to track my estimated 1RM in the graphs. Only thing I wish this app had was a way to keep track of what cycle you’re on and what 1RM you’ve used in past cycles so you don’t accidentally set the wrong one. Besides that this app is basically perfect.

Simple, solid, useful.

The criticism I have to offer is that the app doesn't have a feature which generates which weight plates to use. I've used apps in the past that automatically displayed which weights you needed on the bar for each set like a 45, a 10, a 5, a 2.5 and a 1.25. Barbell math is easy enough but it's nice to just slap on what it tells you to during warmup sets. The only other thing I have is that the rest timer does not continue counting down if you leave the app, so if you check a Facebook notification during a 3 minute rest or leave the app to check that text you got during your last set, your rest timer is jacked. Fix those two things and the app would be nearly perfect. 10/10 would download again. lol.
