About this app

Liftosaur is the most customizable weightlifting app and strength training tracker and planner.

🧠 Automate Your Strength Training

Build your own progressive overload programs or start with proven routines like GZCLP, 5/3/1, or Basic Beginner Routine. Track every workout, visualize your progress, and fully automate your training — all in one smart fitness app.

Stop guessing your next weight. Liftosaur automatically increases or decreases your weights and reps based on the logic you define. It allows to implement any possible progressive overload logic, so you can focus on lifting while the app handles the math.

⚙️ Liftosaur introduces Liftoscript — a simple text language for building workouts like code.
Define exercises, sets, and logic once right in text, and the app updates it automatically after each session.
Example:

```
# Week 1
## Day 1
Bent Over Row / 2x5, 1x5+ / 95lb / progress: lp(2.5lb)
Bench Press / 2x5, 1x5+ / 45lb / progress: lp(2.5lb)
Squat / 2x5, 1x5+ / 45lb / progress: lp(5lb)

## Day 2
Chin Up / 2x5, 1x5+ / 0lb / progress: lp(2.5lb)
Overhead Press / 2x5, 1x5+ / 45lb / progress: lp(2.5lb)
Deadlift / 2x5, 1x5+ / 95lb / progress: lp(5lb)
```

This makes Liftosaur the only scriptable workout app — perfect for lifters who love structure, logic, and data.

This is a fantastic app with a lot of functionality, but it does still come with some bugs and issues. It also has a very limited number of exercises to choose from at the moment and I would like to see more exercises added in future. It also locks certain features behind a pay-wall which is fine in itself but the subscription cost to get access to graphs is very high, and the lifetime purchase for them is £45. I would happily give £10 to have them unlocked but 45 seems ridiculous.

Incredibly comprehensive app, that works no matter how you want to use it. Payment for convenience features is optional and even has a one-off option as an alternative to subscription payments. It's regularly updated and supported by the developers. It was quite overwhelming when I first started using it due to the sheer number of features, but I'm gradually getting used to it as I can clearly track and see genuine progress for the first time! I recommend this to all my gym friends!

It's a really good app, very flexible with many exercises. The descriptions of each show a breakdown of used muscles and how your program works them (in terms of hypertrophy or strength and also how proportional it is across the body). It was sometimes clunky, but considering it's flexibility i would still say it's one of my favourite apps. Sadly it stopped running for me a few days ago, hopefully that will be fixed soon :)
