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.

SwiftUI features and specs

  • Declarative Syntax
    SwiftUI uses a declarative syntax, which allows developers to state what the UI should do, resulting in clearer and more maintainable code.
  • Cross-Platform Support
    SwiftUI allows for creating apps that work across all Apple platforms, including iOS, macOS, watchOS, and tvOS, enabling more efficient code reuse.
  • Live Preview
    Xcodeโ€™s SwiftUI Previews allow developers to see changes in real time without building the entire app, speeding up the development process.
  • Seamless Integration with UIKit and AppKit
    SwiftUI can be easily integrated with existing UIKit and AppKit code, allowing developers to incrementally adopt it.
  • Automatic Dark Mode Support
    SwiftUI provides automatic support for dark mode, simplifying the process of creating themes for applications.

Possible disadvantages of SwiftUI

  • Limited Backward Compatibility
    SwiftUI is only available for iOS 13 and later, which limits its use if targeting older iOS versions is necessary.
  • Growing API
    Since SwiftUI is relatively new and still evolving, some advanced or specific UI components may be missing or not fully optimized.
  • Performance Overhead
    For complex UI setups, SwiftUI can introduce performance overhead compared to UIKit, especially in its initial versions.
  • Learning Curve
    For developers accustomed to UIKit, learning SwiftUIโ€™s declarative style might take some time and adjustment.
  • Bugs and Stability Issues
    As a newer framework, SwiftUI might have more bugs compared to the more mature UIKit and can sometimes lead to stability issues.

Questions & Answers

As answered by people managing SwiftUI 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.
