Liftosaur - the most powerful weightlifting planner and tracker app. Build your weight lifting programs using a simple scripting language - Liftoscript, or simply use one of pre-built popular programs. There're 5/3/1, all the GZCL programs (GZCLP, The Rippler, VHF, VDIP, General Gainz), various programs from Reddit (like Basic Beginner Routine), and many more!

In weightlifting, one of the most important concepts is progressive overload. It means that in order to get stronger and better looking, you constantly need to challenge yourself with more weights or more reps, so that your body adapts and muscle mass increases. When you are beginner, you can just linearly increase weights almost every workout. Eventually you hit plateau, and then you break that plateau by involving more complex overloads and deloads schemes, increasing/decreasing weights and reps by following some pattern.

Liftosaur is an app, that focuses on providing you the tools for progressive overload. It's a weightlifting tracker app, which will increase and decrease weights and reps (and sometimes change sets) according to your performance. It follows some pattern, with the ability to change that pattern in any way you want.

The unique feature of the app is that the programs are written in plain text, using special syntax called "Liftoscript". For example, this is how you could describe a simple beginner weightlifting program:

```
# 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)
```

You can add this text snippet to the app, and it'll use those exercises, and update the weights if you successfully finish all sets by 2.5lb or 5lb (linear progression - "lp").

You'll be able to see weekly and daily volume per muscle group for your program, undulation graphs of exercises week over week, see how much time it'd take in a gym - all the tools that allow you to build efficient and balanced weightlifting programs. And you can easily share those programs with others - either as text snippets or as links.

And then you follow the program and track your workouts! The app will change sets, reps, and weights - adjusting the program text according to how you scripted it!

It has a bunch of popular built-in programs that helped thousands of lifters to get stronger - "Basic Beginner Routine" from r/fitness subreddit, 5/3/1 programs, GZCL programs, etc. All those programs are defined right in the app (using Liftoscript), and completely customizable. You can change every single aspect of them, adjusting to your needs.

The app also has all the features you'd expect from a full-featured weight-lifting tracker app:

• You can log all your workouts, and have access to the history or workouts.
• Rest timers between sets
• Plates calculator (e.g. what plates you need to add to each side of the bar to e.g. get 155lb)
• Ability to track bodyweight and other body measurements (biceps, calfs, etc)
• Graphs of exercises, bodyweight, volume per muscle group, and other measurements
• Choose available equipment (like what plates you have), so that it'd round up weights to match it.
• Substitute exercises to the ones working on similar muscles in case you don't need necessary equipment.
• Cloud backup of all your data, with ability to sign in via Google or Apple Sign In
• Web Editor (https://liftosaur.com/planner) to edit the programs on a laptop so that you can type your programs there

Weightlifting is the long game, and if you're serious about lifting, building strength and sculpting your body, Liftosaur would be a great partner in your journey.
