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.

Questions & Answers

As answered by people managing Zipcodestack 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.

  • I have a column in google sheets with ZIP codes. How do i put a column next to it that will automatically fill with what city is associated with that zip code?
    I have seen this request pop up quite a few times. I did a quick search for free APIs of zipcode lookups. This one, named "zipcodestack" (I'm not in any way tied to, endorsing, or promoting them) seemed like a pretty good resource with up to 10,000 free lookups each month. So, I wrapped a quick script around it and made it a custom sheets function called GET_CITY:. Source: about 3 years ago
