Comments on 531 Strength for Android

★★★★★ sardalamit · Dec 17, 2023

The best program out there. Not to mention the best app! Very simple app with minimalist features just like the program

★★★★★ Tyler Monk · Sep 30, 2024

If you're on the fence, give it a shot. I was apprehensive after switching back to Android and losing the app I was using. There's another app that I feel is better, but I just can't bring myself to pay $10 for it. This app you set your weights, and you can click each set which will put a checkmark on it, so you don't lose where you're at. It will allow you to adjust your weights after reload week. Uncheck whatever workouts you don't want to add weight to then +/- the ones you do. Great app. Simple.

★★★★★ Earnest Bostick · Apr 11, 2023

Great app I love the 531 workout and this is the best app I have used.

★★★★☆ Joseph V · Jun 8, 2026

Could be great, but why is there no way to track accessory work outside of notes on the main lifts? This works fine for super setting, but it seems individual accessory work is overlooked.

★★★★☆ Giuseppe Mancone · Feb 21, 2023

Great app! Workout timer, logs, graphs, reasonable interface. Things I'd love: - Would be nice to see if the last workout was a 5, 3 or 5/3/1 day without going into the log - Saving additional sets into the log would be nice, too. - Automatic sync with Google Drive would be so sweet - Option to make all the graphs use the same time frame, regardless of data points for that exercise - Show top set/date on each data point on graph when clicked

★☆☆☆☆ Dominic · Sep 17, 2022

Why is there no calendar or tracking like in IOS version? It should have that or there's no point in having the app. I wasted ten doars after switching to android but it isn't optimized
