RepDB is a one-time-purchase exercise dataset with animations for developers building fitness and workout apps — 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 600+ exercises with flat-style 512×512 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 — 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.

C4droid features and specs

  • Portable C/C++ Development
    C4droid offers the ability to write C/C++ code directly on Android devices, making it highly portable for developers who need to code on-the-go without the need for a desktop or laptop.
  • Offline Compiler
    It includes an offline GCC compiler that allows users to compile their code without needing an internet connection, which enhances convenience for users in remote areas or with limited connectivity.
  • Plugins Support
    C4droid provides support for third-party plugins which can extend its functionality, such as SDL and Qt libraries, enabling more advanced development opportunities.
  • User-friendly Interface
    The application offers an intuitive interface that is relatively easy to navigate for both beginners and experienced programmers, shortening the learning curve required to use it efficiently.

Possible disadvantages of C4droid

  • Limited Performance
    Running heavy or complex projects on an Android device through C4droid might result in slower performance compared to using a full-fledged PC or a dedicated development environment.
  • Hardware Limitations
    Programming on mobile devices inherently comes with challenges such as smaller screen sizes, limited processing power, and constraints in multitasking, which can hinder productivity and ease of use.
  • Paid Features
    Certain advanced features and functionalities within C4droid may be restricted to the paid version of the app, potentially limiting its accessibility for some users who rely on free tools.
  • Limited Language Support
    While it is powerful for C/C++ development, the app is limited in supporting other programming languages, which might be a drawback for developers who work with multiple languages.

Questions & Answers

As answered by people managing C4droid and RepDB.

What makes your product unique?

RepDB's answer:

RepDB is sold as a one-time download, not a metered API — 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 — 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.
