"Very good app. I've used 531 app by the same developer earlier (and that worked well for different 531 variations). This app allows more workouts and further customizations. I like how workouts can be designed based on a percentage of training max. There were a few bugs initially, but the developer has been very responsive and fixed all the issues pretty fast."

Najih

"Best workout logging app by far and very customizable. Love the option to pay once to unlock what you need without need for subscriptions. Still somewhat early in development but the developer is very responsive to bug reports. I'm on my way to getting swole thanks to this app."

Chris

"I've never found a more adaptable and intuitive interface for 531. It's also nice to not have to pick a different app when I want to take a break from powerlifting and do a more bodybuilding split. A+."
