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.

Swift features and specs

  • Performance
    Swift is designed to be high-performance, often running faster than Objective-C due to its modern language constructs and optimized LLVM compiler.
  • Safety
    Swift includes features like optionals, type inference, and safe memory management to reduce common programming errors and crashes.
  • Readability
    Swift's syntax is clean and less cluttered, making it easier to read and maintain.
  • Interoperability
    Swift is fully interoperable with Objective-C, allowing for easy integration with existing iOS and macOS projects.
  • Modern language features
    Swift includes modern programming concepts such as closures, generics, and tuples which can help developers write expressive and efficient code.
  • Memory management
    Swift uses Automatic Reference Counting (ARC), which helps in efficient memory management without requiring manual intervention from the developer.
  • Active community and support
    Swift has a large, active community and strong support from Apple, ensuring continuous evolution and community-driven improvements.

Possible disadvantages of Swift

  • Newness
    Being relatively new compared to languages like Objective-C, Swift is still evolving, which might lead to occasional stability issues or breaking changes with new updates.
  • Limited legacy support
    Swift does not work with versions of iOS and macOS older than iOS 7 and OS X 10.9, limiting its use in maintaining really old applications.
  • Learning curve
    For developers accustomed to Objective-C or other languages, there is a learning curve associated with familiarizing themselves with Swiftโ€™s new syntax and features.
  • Smaller pool of third-party libraries
    Although growing, the ecosystem of third-party libraries for Swift is still smaller compared to more mature languages, potentially limiting immediate availability of tools.
  • Binary compatibility
    Binary compatibility issues can arise, especially when working with a mixed codebase of Swift and Objective-C, requiring extra caution during implementation.
  • Tooling maturity
    Some of the development tools and environments, while robust, can still be less mature compared to the well-established Objective-C tooling.

Questions & Answers

As answered by people managing Swift 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.
