This app is much better than the Vandersoft 5/3/1 app that I paid for. It’s simpler, and it’s not trying to be “extra.”

You have to pay a fee to change percentages, another fee to use a calendar, another fee for a plate calculator, another fee to track more accessories. This is ridiculous. Sadly this is the only decent app for 5/3/1.

This app is great and does all the math for you if you follow the Wendler method.

Worth the extra $2 for the plate calculator.

For those wanting to follow Wendler’s 5/3/1 “boring but big” program, this is by far the best app to help drive gains. Tried a few others inclusive of my own excel sheets and this app accomplished everything I was looking for. Simple, uncluttered UX with the ability to add notes for your future self. Will take some prior knowledge for how to run the program, but this app is just the tool to help keep you on-track and pushing those PRs! Kudos to the developer!

The base app is awesome for what it is and it makes training really simple. Adjustments and improving is easy and straight forward. The only drawback is the Pro upgrade isn’t worth what they charge, and can be done easily on a spreadsheet. I’m not going to remove stars for it because I love the free version and it makes my life easier.

Similar to other reviewers, I feel the app is excellent. As a user that purchased all of the additional pieces, it would be nice to have the ability to add a total of five additional sets instead of just one. That would allow a user to also complete the "Boring but Big" variant of the system.

I really love how simple and convenient this app makes everything! All I need is a full charge, head phones, preworkout, and I can have one of the best workouts every time I step in the gym using this app! The app is free but I recommend just spending the extra money on a graph and the log/graph for accessory lifts as well! It is so cheap in comparison to a powerlifting coach and makes accountability that much easier as well as much more digestible feedback than what you feel like from session to session. Very satisfied with the in app purchase and definitely the best app on the market for powerlifting!
