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.

NativeScript features and specs

  • Cross-Platform Development
    NativeScript allows developers to write code once and deploy it across multiple platforms, including iOS and Android, which saves time and resources.
  • Native Performance
    Since NativeScript directly uses native components, it delivers high performance comparable to native applications, unlike some other cross-platform solutions.
  • Rich Ecosystem
    NativeScript offers a rich ecosystem of plugins and modules, making it easy to extend functionalities and integrate with various services.
  • Single Codebase
    Maintaining a single codebase for both iOS and Android reduces development and debugging efforts.
  • Open Source
    Being open source, NativeScript has strong community support and continuous improvements driven by developers around the world.
  • Access to Native APIs
    NativeScript allows direct access to native APIs, giving developers more flexibility and control over platform-specific features.

Possible disadvantages of NativeScript

  • Steep Learning Curve
    The framework requires an understanding of native development concepts, which can be complex for new developers or those not familiar with mobile development.
  • Lack of Third-Party Components
    Compared to more mature frameworks, NativeScript has a limited number of third-party libraries and UI components available.
  • Performance Overhead
    Despite high performance, there is still some overhead compared to fully native applications due to the abstraction layer.
  • Limited Community Support
    Although the community is growing, it is still smaller compared to mainstream frameworks like React Native or Flutter, which might result in slower issue resolution and fewer resources.
  • Maintenance and Updates
    Keeping the framework and its plugins up to date with the latest iOS and Android releases can be challenging and resource-intensive.

Questions & Answers

As answered by people managing NativeScript 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.
