Liftosaur Product Information and Latest Updates (2025)

Hello Product Hunters! 🏋️‍♂️ I made a free PWA phone app for tracking weightlifting progress - Liftosaur. Yup, like thousands of other weightlifting tracker apps, but mine has one unique feature - you can write code right in the app! It has powerful exercise editor, where you can define the logic for progressions and deloads using built-in scripting language Liftoscript. Like, you can express that after 3 successful Squat sets you want to increase the weight by 5lb, or decrease weight if you didn’t hit 12 reps total, or anything like that. It also has all those features all other weightlifting trackers have - ⏱ rest timers, ➕ plate calculator, 🖋 history editing, ☁️ cloud storage, 📈 progress graphs, etc, etc. You don’t have to be weightlifting expert to use it though. It contains a bunch of prebuilt programs (built by using the same built-in scripting language Liftoscript) from https://thefitness.wiki - IMHO the best starting guide for those who wants to get into weightlifting. So, you could start with “Basic Beginner” routine, and after 3 months of running it switch to GZCLP or 5/3/1 For Beginners. All you need is to read about the program in the wiki, and then just do whatever app tells you to do, it will handle progressions and deloads properly for you. 📱It’s a PWA (Progressive Web App), meaning you can use it just by opening in a browser on your phone, and if you like it - you can add it to home screen, then it will look and behave like a regular app. I got into weightlifting, like many others, starting with Stronglifts 5x5. It has a very nice app, so I used it while running the program. After a while though, I got bored of that program, and wanted to switch to 5/3/1, but that means I have to change the app, and lose my progress. I found another app for 5/3/1, and was running it for a while, but then, I wanted to make some adjustments and add some progressions logic for assistance, but couldn’t do that in that 5/3/1 app I was using. And I thought - would be cool to have an app where you could design any logic you want for your workouts, and don’t have to jump from app to app and lose your saved history when doing that. So here’s my app got born. After a lot of trial and error and figuring out the best ways to built-in scripting language into a phone app, but make it in a way that you don’t have to use it if you don’t want to, I finally am pretty happy with the result, and presenting my work to the Product Hunt community. Excited to hear your feedback! ❤️ Follow it on twitter @liftosaur :)

Great! Very useful. Could have been nice if there were more powerlifting programs like Starting strength and Texas method.
