RepRaptor is a community workout app for building, sharing, and running training programs. Publish a program to the discovery feed and anyone can find it and run it. Browse what the community has built, follow a program from your coach, or start from an official template.

Build two kinds of training. Classic programs run on weeks, days, exercises, sets, and rest for strength blocks, hypertrophy, and periodized plans. Circuit programs run on timed rounds for HIIT, EMOM, AMRAP, Tabata, and finishers. Every exercise pulls from a library of 1,796 moves, already tagged and searchable by muscle, equipment, or category, and you can edit any of them.

Coaches get a full platform. Build programs for clients, message them inside the app, bundle plans together, and share links that track which channel sends signups. An activity feed shows who's training and flags anyone quiet for a week. Pricing is flat with no fees per client.

Free for lifters. On iOS and web, with Android coming.

LibreFit features and specs

Free and Open Source
LibreFit is a free and open-source calorie tracking and weight management application, meaning users can use it without any subscription fees or hidden costs, and the source code is publicly available for transparency and community contributions.
Privacy-Focused
As a self-hostable application, LibreFit allows users to keep their health and fitness data under their own control rather than storing it on third-party servers, which is a significant advantage for privacy-conscious users.
Simple and Lightweight
LibreFit focuses on core functionality like calorie tracking and weight logging without unnecessary bloat, making it straightforward and easy to use for people who want a no-frills approach to fitness tracking.
Self-Hostable
Users can deploy LibreFit on their own server or infrastructure, giving them full control over their data, uptime, and customization without relying on external service providers.
Modern Tech Stack
LibreFit is built with modern web technologies like SvelteKit, making it responsive and performant as a progressive web application that works well across different devices and browsers.

Possible disadvantages of LibreFit

Limited Food Database
Unlike commercial alternatives such as MyFitnessPal or Cronometer, LibreFit likely lacks a comprehensive, pre-populated food database with millions of entries, requiring users to manually enter nutritional information for many foods.
Requires Technical Knowledge to Set Up
Being a self-hosted application, LibreFit requires some technical expertise to deploy and maintain, which can be a barrier for non-technical users who just want a simple app to download and use immediately.
Smaller Community and Support
As a niche open-source project, LibreFit has a much smaller user community compared to mainstream fitness apps, meaning fewer resources, tutorials, and community support are available when users encounter issues.
Limited Features Compared to Commercial Alternatives
LibreFit may lack advanced features found in commercial fitness apps such as barcode scanning, meal planning, exercise tracking, social features, wearable device integrations, and detailed micronutrient breakdowns.
No Dedicated Mobile App
LibreFit operates as a web application rather than offering dedicated native iOS or Android apps, which may result in a less polished mobile experience and lack of features like push notifications or offline access compared to native fitness apps.

Questions & Answers

As answered by people managing LibreFit and RepRaptor.

What makes your product unique?

RepRaptor's answer:

RepRaptor does two things and skips the rest. You build training programs and you run them. No social feed, no marketplace taking a cut, no per client billing. Coaches pay one flat monthly rate no matter how many clients they carry. The same app handles structured strength blocks and timed circuits, and anyone can publish a program to the community for others to run.

Why should a person choose your product over its competitors?

RepRaptor's answer:

Most coaching platforms charge per client or take a percentage of what you earn. RepRaptor is built the other way:

Flat pricing. One monthly rate by client capacity, so growing your roster never raises your cut.
Free for lifters. Clients use the full app at no cost, which makes onboarding easy.
Two builders in one. Linear programs and timed circuits, so you are not locked into a tool that only does one.

What's the story behind your product?

RepRaptor's answer:

Training apps kept piling on things that had nothing to do with training. Social feeds, badges, upsells, per client fees that punished coaches for growing. RepRaptor started as the opposite. Strip it down to building and running programs, keep lifters free, and charge coaches one flat rate. It is built by a solo developer who wanted a clean tool for finding and following good programs.

How would you describe the primary audience of your product?

RepRaptor's answer:

RepRaptor serves two main groups, plus the creators who sit between them:

Coaches and personal trainers. Online and in person, from solo trainers up to small gyms, who build programs and deliver them to clients.
Lifters. People who want to follow a solid program and track their training without a cluttered app.

Creators sit in between, publishing programs to the community for anyone to run.

Which are the primary technologies used for building your product?

RepRaptor's answer:

Frontend. Vue and Pinia, styled with Tailwind.
Mobile. Capacitor, one codebase for iOS and Android.
Backend. Supabase, which is Postgres with row level security, plus AWS Lambda for serverless functions.
Payments. Stripe on web, RevenueCat on mobile.
