Just Fantastic

I almost never leave reviews for anything. So it says something about how good this app is that I break that pattern to write a positive review. Liftosaur works so well. The scripting feature lets me design the workouts exactly how I want it to. I can adjust every detail of the lift and progression so that it’s perfect for what I want to do. And when I’m actually lifting it’s incredibly simple and easy to keep track as I go and I don’t need to think about logging anything or keeping up with where I am. The free version is great and if you like it as much as I do there is a one time payment for a lifetime subscription which I love not needing another subscription. The free version is great so I’d definitely give it a try if you’re looking for a way to take some mental weight off your lifts.

Best workout app I’ve tried!

Absolutely love this app! It’s honestly the best workout tracker I’ve tried. I told ChatGPT what I wanted to work on and what my goals were, it created a workout program for me, and now I track everything in Liftosaur. I can easily change exercises, adjust the weight and reps, and edit the program whenever I need to. Super flexible, easy to use, and exactly what I was looking for. Highly recommend! 💪🦖

Very powerful app

Packed with features for the free version, this app is excellent and made me enjoy going to the gym a lot more. Although there is a bit of a learning curve, it's worth learning to be able to utilize the app. Will use this for as long as I can

Extremely useful

For those self coaching and using available spreadsheets this is invaluable, being able to add any sheet I want by showing codex and having it write it directly into liftosaur, and then adjust as needed and compare against other things I’ve done etc is great, not to mention the ease of logging my sets any way they need to be whilst working out in the app!

Mostly solid but lacks some features I’d like

I like a lot of the things this app tries to do. The main downside right now is that there is no way to create an ad hoc workout from a past workout, and there is no way to save a past training day to an existing program. Also the Apple Watch notifications are bugged and the sound always plays no matter what which is annoying enough for me to not use it.
