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 250 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.

  • Potential Stability Issues
    As with many open-source projects, the software might face stability issues or bugs that are not immediately addressed unless reported and fixed by the community.
  • Feature Set
    While NoteKit covers the basics well, it may lack some advanced features found in more established note-taking applications, such as cloud synchronization and collaboration tools.
  • User Interface
    The user interface may not be as polished or intuitive as that of commercial note-taking applications, which can be a barrier for new users.

Questions & Answers

As answered by people managing NoteKit 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.

  • Notes: Fast note-taking app, open-source, without Electron, built in Qt C++
    I use NoteKit[0], one of the nicest things about it is that a can paste an image and draw on it, simple yet useful. Does "Notes" offer the same functionality? And what about spell check?

  • Typora is no longer free. Is there a good alternative or replacement?
    Slightly late response, but I'm working on one, with a particular focus on tablet input: notekit. There isn't quite feature parity with Typora since using native instead of HTML-based rendering makes things like tables hard and many aspects of it are still work in progress in general, but several people (including myself) do already use it on a daily basis.
