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.

    While great for practice, Codewars does not provide comprehensive tutorials or in-depth explanations, which are often needed for mastering complex concepts.

Questions & Answers

As answered by people managing Codewars 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.

Codewars mentions (160)

  • Of recursion and backtracking
    Recently, I was working on a coding kata on codewars.com. Early on, I started thinking that a potential solution might utilize recursion, a concept that involves a function calling itself. However, I quickly realized that my grasp of recursion was not as solid as it needed to be for this task. In this post, I will share the insights gained from deepening my understanding of recursion while working through the kata. - Source: dev.to / over 2 years ago
  • 4th year, about to fail an entire semester's worth of classes.
    Get more involved. Look into internships and junior SWE positions to get a sample of what you'd be applying for once you graduate. Solve coding challenges, start working on a portfolio of your personal works. I recommend codewars.com for coding challenges, it's fun. Source: over 2 years ago
  • Beginner with C++ looking for direction
    I'd recommend to play around with some basic coding challenges on leetcode.com or codewars.com. If the course prepared you well you won't find this useful, but playing around with them will make sure that you are comfortable with basics such as loops, if statements etc. Source: about 3 years ago
  • Can you guys recommend an efficient way to learn in advance IT para sa mga walang alam?
    I would advise for you to start with Python, it's a beginner-friendly programming language and it'll help with wrapping your mind around things. Play around with it, perhaps do some katas on CodeWars and you'll be set. Source: about 3 years ago
  • How do I develop programming logic?
    There is a website called codewars.com where you can select problems of varying difficulty for the language you need. It is very helpful for learning. Source: about 3 years ago
