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.

Quantum Moves features and specs

  • Citizen Science Engagement
    Quantum Moves engages a wide audience by allowing them to contribute to real scientific research without needing a specialized background in quantum physics.
  • Data Collection Efficiency
    The game provides an efficient means to gather large amounts of data on problem-solving strategies, which can be used to improve quantum computing algorithms.
  • Educational Outreach
    Quantum Moves serves as an educational tool that helps to increase the public's understanding of quantum mechanics in an interactive and accessible way.
  • Innovative Problem Solving
    Human intuition in the game can offer novel solutions to complex quantum control problems that might not be easily found by traditional algorithms.

Possible disadvantages of Quantum Moves

  • Limited Expertise Translation
    The strategies used by players do not directly translate into actionable strategies in quantum computing as players are not experts.
  • Data Noise
    The involvement of non-experts may introduce noise in the data collected, making it challenging to discern usable strategies.
  • Over-simplification
    In order to be accessible to a broad audience, the game simplifies complex quantum phenomena, which might limit the depth of insights it can provide.
  • Resource Intensity
    The development and maintenance of the game and platform require significant resources and effort, which might not always result in proportionate scientific benefits.

Questions & Answers

As answered by people managing Quantum Moves 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.
