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.

Great app, open platform = great AI

Great app. Really appreciating the bring-your-own ai integration. Little things like being able to set up all the dumbbell weights in the gym by taking pictures of the 3 racks of weights and then asking Claude to update the weights in liftosaur via its mcp server in 5 seconds is just the sort of integration that makes liftosaur so great

So good

Best app I’ve ever used for anything ever. The dev is on Reddit as well and he fixes everyone’s problems almost instantly it’s great to see.
