Best workout app I’ve ever used

I wish every app, fitness or otherwise, would follow this app’s lead. The layout, the functionality, the one-time purchase option for additional features — it’s no exaggeration to say this app is flawless, a must-have for anyone using 5/3/1.

Widowmaker?

Hello, love this app. Are you able to add widowmaker sets as an option?

Good but

This app is much better than tracking 5/3/1 with a spreadsheet, isn’t a bloated mess like other apps and has zero ads. Almost perfect.

However, it’s disappointing that only a mens bar is the default option and setting a womens bar is locked behind a paywall as if being a woman is some niche or unique customization.

Hopefully the dog looks into this and reconsiders.

Great Results

I really enjoy using this, I have been using it on and off for a while and find it gives me good results.

Love it

I love the simplicity, but would just ask for the ability to add FSL to 5’s Pro.
