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.

TweakSync is a productivity-boosting tool for front-end developers, enabling real-time style changes and seamless syncing between Chrome and VS Code. With TweakSync, developers can make visual tweaks to CSS, HTML, or React components directly in the browser, preview them instantly, and push those updates back to their codebase in VS Code with a single click. This eliminates the tedious back-and-forth between the code editor and browser refreshes, helping developers stay focused on building and refining web designs. TweakSync is perfect for any developer who wants to streamline their workflow, particularly those working on responsive designs, rapid prototyping, or collaborative projects. The ability to see real-time updates in the browser makes it easier to test different screen sizes and devices without having to manually write and test every style change. Additionally, TweakSync helps bridge the gap between designers and developers by allowing design adjustments to be previewed in real time before they are committed to code. Our tool gives developers total control over the syncing process. Instead of automatic updates that could lead to errors, TweakSync uses an "Apply" button, letting users decide exactly which changes to commit to their codebase. This ensures precision and reduces the chances of unintentional updates, leading to cleaner, more efficient code. Key features: Real-Time Styling in Chrome: Instantly preview and adjust CSS/HTML directly in Chrome. One-Click Sync to VS Code: Apply your changes back to your codebase with a single click. Improved Workflow Efficiency: No more switching between browser and editor; everything happens in real time. Responsive Design Testing: Quickly test and tweak designs across different screen sizes and devices. TweakSync is available as both a Chrome extension and a VS Code extension, making it easy to integrate into your existing toolset.

Questions & Answers

As answered by people managing RepRaptor and TweakSync.dev.

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.

TweakSync.dev's answer:

TweakSync is unique because it offers a seamless integration between Chrome and VS Code, enabling developers to style web pages in real-time within Chrome and then sync those changes directly back to their codebase in VS Code. This integration bridges the gap between visual design and coding, streamlining the development workflow and saving time.

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.

TweakSync.dev's answer:

TweakSync stands out from its competitors by providing a combined solution for real-time visual styling and code syncing. While other tools may focus on automatic browser refreshing or live previews, TweakSync allows developers to make live style adjustments in Chrome and apply those changes directly to their codebase in VS Code, offering a more cohesive and efficient workflow.

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.

TweakSync.dev's answer:

The primary audience for TweakSync consists of front-end developers, web designers, and full stack developers who are looking for a more efficient way to style web pages. They are experienced with coding and seek tools that enhance their workflow by providing real-time feedback and seamless integration between their development environment and browser.

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.

TweakSync.dev's answer:

TweakSync was created out of frustration with the cumbersome process of switching between Chrome and VS Code while styling web pages. Coming from a background in mobile game development, where real-time visual feedback is crucial, I wanted to bring that efficiency to web development. TweakSync bridges the gap between visual styling and coding, helping developers streamline their workflow and improve productivity.

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.

TweakSync.dev's answer:

Vite: For fast and efficient development and build processes. React: For building interactive and dynamic user interfaces in both the Chrome extension and VS Code extension. TypeScript: For enhanced code quality, maintainability, and type safety. Tailwind CSS: For modern, utility-first styling of user interfaces. WebSocket: For real-time communication between the Chrome extension and VS Code. Node.js: For server-side functionality and managing data synchronization.

Who are some of the biggest customers of your product?

TweakSync.dev's answer:

Our customer base is growing steadily as more developers adopt TweakSync. I'm currently onboarding new users and gathering feedback to enhance our product.
