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.

Awesome app that is easy to use and keeps you focused on the training. Easy to rearrange what order you do the exercises, swap exercises or add sets, kgs etc. You also get full access to a website where you can make your own programs, or use pre-made programs. Bought the lifetime version after completing my first workout. Awesome stuff!

Love this app! Simple straight forward workout app with plenty of customization possible. I mainly use it for just simple ad-hoc workouts, so nothing strict and I find it's the easiest app for me to use and keep record of my lifts . Loved it so much I got the lifetime subscription. Wife still uses the free version which works very well for her needs. Still she gets good customization and usage out of it. Incredible app, would recommend to all! Plus the name/mascot is awesome!

Best workout app I've used. Infinitely customisable workout routines and programs, with automated progression mechanics, you can set it up exactly how you want, from setting different rest timers for every set, to logging RPE, supersets, mesocycles, programs that change week to week. Features regularly being added. Very responsive developer.
