RepDB is a one-time-purchase exercise dataset for developers building fitness and workout apps โ€” not a subscription, not a rate-limited API. You download the data once and own it: JSON (and SQLite on the higher tier), WebP images, and full EN/DE/ES translations, with no per-request billing and no dependency on our servers staying up.

A free tier includes 400 exercises with flat-style 512ร—512 images, attribution-licensed for commercial in-app use. The Starter tier ($199) adds the full catalog in classic white-background style. Standard ($399) adds transparent 1024px images, looping animations, exercise relations (similar/progressions/regressions), workout templates, and embeddings โ€” exclusive to that tier.

Every exercise includes muscle-group highlighting, equipment/muscle icons, MET values, and safety/goal tags. Compared to GIF- or JPG-based competitor APIs, RepDB images are transparent WebP with no watermarks, so they drop into any app UI without a white box around them.

Possible disadvantages of Capacitor by Ionic

  • Performance Overhead
    Since it functions as a bridge between web and native technologies, there can be performance overhead compared to pure native applications.
  • Less Mature Ecosystem
    Compared to more established alternatives, Capacitor's ecosystem is still growing, which might result in fewer plugins and community resources.
  • Learning Curve
    Developers who primarily work with pure web or native technologies might face a learning curve when adapting to Capacitor's unique blend of web and native paradigms.
  • Platform-Specific Limitations
    Some native functionalities may not be fully supported or may require platform-specific adjustments, which can complicate development.
  • Dependency on WebView
    Capacitor-based applications rely on WebView, which can lead to inconsistencies and limitations on different platforms and versions of Android and iOS.
  • Initial Setup Complexity
    Initial setup can be more complex compared to pure web or native projects, as it involves configuring multiple platforms and ensuring compatibility.
  • Regular Updates Required
    Frequent updates and changes in Capacitor and its plugins can require developers to regularly update their projects, leading to potential maintenance overhead.

Questions & Answers

As answered by people managing Capacitor by Ionic and RepDB.

What makes your product unique?

RepDB's answer:

RepDB is sold as a one-time download, not a metered API โ€” you own the JSON/SQLite data and WebP images outright, with no rate limits, no per-request billing, and no risk of the vendor cutting off access. It's also the only dataset in this space with EN/DE/ES translations, transparent (alpha-channel) images with no watermark, muscle-group highlighting, safety/goal tags, and looping animations on the higher tier.

What's the story behind your product?

RepDB's answer:

RepDB grew out of a consumer workout app its creator was building solo. Sourcing exercise images and data meant either paying for a subscription API with usage caps and no caching rights, or producing everything from scratch. The illustrated, multi-language dataset was built for us first, then split out as its own product once it became clear other indie developers had the same problem and preferred to buy the data outright rather than rent it through an API.

Why should a person choose your product over its competitors?

RepDB's answer:

Most alternatives are subscription APIs โ€” you pay monthly, you're capped on requests, and ExerciseDB's terms of use explicitly forbid caching or storing the data at all, so every image render is a live paid API call. RepDB is the opposite: pay once, download the files, self-host with zero ongoing dependency. It's also the only option offering true DE/ES localization and transparent images instead of a white box behind every exercise.

How would you describe the primary audience of your product?

RepDB's answer:

Solo developers and small teams building fitness or workout-tracking apps (iOS, Android, web) who need licensed exercise images and structured exercise data, but don't want to build their own media pipeline or depend on a rate-limited third-party API.

  • From Claude Artifact to Production PWA: Building VitaminD Explorer
    For now, the tradeoff is clearly worth it. If the app grows to need native APIs (wearables, health data), a hybrid approach with Capacitor or a thin native wrapper around the existing web app would be the natural next step โ€” not a rewrite. - Source: dev.to / 3 months ago
  • The tech stack behind InkRows
    Capacitor handles the cross-platform piece. I write the app once in React/TypeScript and deploy to web, iOS, and Android without maintaining separate codebases. It bridges web and native APIs through plugins, so I can access native features like the camera and system functionality when needed. - Source: dev.to / 7 months ago
