Best 531 app out there

I’ve been using this app for the past three years training using the 5/3/1 program. Does the calculations so you can focus on getting stronger. Follows the program including the main variations. Allows custom assistance exercises to be added as well. All the typical tools like plate loader calculations are included. I really like the 1 rep max and volume graphs to show progress too. My only recommendations would be:
1. Allow negative weight numbers for beginners on body weight exercises like band-assisted dips and band-assisted pull ups,
2. Add an option to record zero reps to allow failures on the last set of the 5/3/1 week, and
3. If a zero is recorded on that final set, add an option to automatically adjust down your training max per the Wendler calculations.
Even without these upgrades, it’s a great app. Money well spent.

Quirks and Bugs but overall good

I will give it a 4. Could have been much better. The asistance exercise list is not large enough. There is not even a bent over row listed. So when I try to add one to the list it doesn't except, gives me an error pop up for a millisecond that I can not even read. Also when I went into settings to see if the assistance exercise list would change to change the template, all my recorded exercises are gone from the previous sessions. I have to now setup all new assistance exercises for the routines. When you by mistake save a session well good luck, it seems like there is no turning back. You should be able to go to calendar and delete that session. Other quirks exist. It is a good and simple app but can be definitely a lot better. Make user interface that data can be added or taken out, and if a session is not saved intentionally give the option to re-do the session.

Pretty good

Says it has apple watch support. I have a suunto though not an apple watch so I don't care about that. Wish the assistance exercises were part of the program you pay for but I can live without them and just do them myself. Overall it's a good app and I like it better than some others I've tried. Few things here and there that could be better but overall well built app that allows you to get work done and keep track of your progress. One thing that does kind of annoy me is that if you are adding reps on your last set and you needed 8 reps to beat your 1RM but you only did 7 reps but accidentally hit 8 it will give you a star with your new 1RM but when you back it down to 7 it doesn't take that away. It's like once you hit it you hit it. Paid for the main app after trial but won't pay for assistance exercises or for Apple watch support. They are not worth it IMO.
