RepDB
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 250 exercises with flat-style 512ร512 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.
Human Resource Machine RepDBRepDB'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.
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.
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.
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.

3rd grade might be a bit young, but you can make simplified version of the 4917 computer https://punkx.org/4917/ and make few funny self modifying programs they can "compute" on pen and paper also maybe get few examples from human resource machine and play them out, this might be more fun than pb&j https://tomorrowcorporation.com/humanresourcemachine. - Source: Hacker News / 10 months ago
This is pretty much `assembly language the game`: https://tomorrowcorporation.com/humanresourcemachine It's not a useful architecture, but it teaches the thought process really well, and you end up discovering a lot of optimization naturally. - Source: Hacker News / about 3 years ago
Other options have been given in this thread and I'd agree that for this particular situation the Tomorrow Corporation's "Human Resource Machine" is probably the best match. It's a constrained environment in a game that scales up to introduce this and more. Source: over 3 years ago
Not sure if 7 is old enough, I made this card "game" with my daughter when she was 10: https://punkx.org/4917/ which is not really a game but more like a puzzle, you have 54 small programs for a 4 bit made up computer (Richard Buckland's computer) and you have to interpret them in your head or with pen and paper. It's quite interesting to play with her when I change few instructions on a card. Other interesting... - Source: Hacker News / over 3 years ago
