Comments on 1 Rep Max Calculator and Log for Android
★★★★★Mitch Royer· Jan 22, 2025
Great app to track your strength gains. It is pretty accurate as far as 1RM goes, but I wouldn't treat the projection as gospel. Always use caution. I would, however, like the ability to group exercises per body part. Example: Main lift: deadlift, secondary supporting: RDLs, good mornings, etc... It would make tracking exercises a bit easier in my opinion. Overall, I do not regret upgrading to the pro version, and I would endorse anyone to use this app for strength logging.

I love how it gives you a wide range of weights and reps based on your input.
★★★★★Brett Ankawi· Jun 25, 2024
Simple app that does exactly what it tells you it'll do. Based on your input of weight lifted for however many reps, gives you your estimated 1 rep max and estimated maxes for other rep schemes (2 rep max, 3 rep max, etc.)

Would have been 5 stars, except for the fact that I paid for the pro version, and it doesn't register - I am still bombarded with ads and can only input a limited number of exercises. Needs fixing ASAP, and then it would be 5 stars.
