### 3/5 — It does a decent job keeping track

*2026-08-05, version 10.2*

I wish it was better interstates where it tracks and transfer data for  actual bodyweight. 
I wish that the app would do a better job, adjusting weights for exercise that I added

### 5/5 — Powerbuilding

*2026-07-11, version 10.2*

Great program to build strength and muscle

### 5/5 — Such an amazing app!

*2026-06-17, version 10.2*

I’m so glad to find this app. Makes following the 531 program so easy. It has all the features you need. On top of it, you can purchase it for a lifetime. Such a great developer!!

### 5/5 — Now it is a five+

*2026-05-21, version 10.2*

05/20/26 Still a 5!

9.24.24 I have no idea when I wrote the last review but this still remains the best 5/3/1 app out there! Developer responded to my review with a little insider info, “Long press on the weight amount and a box will pop where you can enter weight in digits!”

Old review: Would have been 5 stars but the only way to change the weight in a lift is by using the +\- at .5 increments! Might be away to adjust the rate of change in the settings but haven’t found it.

The authors get major props for the options and functionality they built into this thing!

### 5/5 — Great app for base 531 lifting.

*2026-03-06, version 10.1*

This app is great for basic 531 lifting (BBB, FSL, and so on). It missed a lot of what’s in Beyond, but you can probably brute force it in if you wanted to. 

There is also a great Apple Watch integration to feed your lifting information to your hand so you aren’t having to constantly keep checking your phone. Great for lifting so I can try to come out a bit, it’s as close as you can get to pen & paper but with the convenience of an app. 

A couple minor (again - very minor) complaints:

One is that the watch app frequently seems to forget you are lifting and loses your workout progress. It almost seems to never recognize if it’s in a session and run in the background. I am unsure what causes it but it happens quite frequently. Not the worst issue to go back into the app to send info back to your watch though, but it would be nice if the active workout didn’t lose progress so frequently if the watch goes to sleep for a brief moment. 

Two is that editing your template can be a bit of a pain with an unnecessary learning curve. Once you know where you can edit from (Settings > Templates) it isn’t too bad, but it seems unnecessarily complicated for simply adjusting accessory lifts

It is still a 5/5 app though.

### 5/5 — Great Weightlifting app

*2026-02-03, version 9.9*

I like this app because it is simple, helps you improve steadily, and it’s free.

### 5/5 — Rare gem

*2025-11-24, version 9.7*

One of those apps that I would miss if I didn’t have it. Organized logically, includes timers, and automatically adjusts your 1RM based on your performance. I bought the Apple Watch extension, but I’ve yet to try setting it and leaving my phone in the car. Regular app definitely worth the price.

### 5/5 — Absolutely Worth the Money!

*2025-09-13, version 9.6*

I use this app religiously every week.  I’ve been tracking progress and following the programming it sets up for me for over two years now.  My overall strength has steadily increased.  I’m 64 years old and my total for bench/squat/deadlift has methodically increased from the mid-700’s to over 1000 lbs through following the 531 methodology.  The app has several great features like a plate loading function that uses the weights you own to then quickly tell you what to load on the barbell so you don’t even need to do any gym math.  It can also set up programming for alternative lifts like front squats or dumbbell bench press, etc.  Bottom line, if you have the patience and commitment to do the work, this app is a fantastic tool to help you achieve your goals. This has been worth every penny!

### 5/5 — Only dev that values privacy

*2025-08-27, version 9.6*

Try this 531 app, this dev will NOT scrape ALL your personal data. For that reason alone I give it 5 stars.
And the app is great, and well maintained

### 5/5 — Unbelievable

*2025-08-13, version 9.5*

Way exceeded my expectations
