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 400 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.
Magic Lantern 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.

Grab an old DSLR off eBay, and get a suitable dummy battery DC adapter and intervalometer for it. If you get a Canon that Magic Lantern supports, you can use a software intervalometer instead. I'm seeing people sell Canon T3's with kit lens for <$100 on Ebay right now (though check descriptions to make sure they actually work!). Source: about 3 years ago
If you're already in the Canon ecosystem, why not just get a used 5D mark III? Using Magic Lantern you can then record 3.5K RAW 14bits footages (usable directly under Resolve), may be enough to learn color grading. Source: about 3 years ago
> How raw is raw? Certainly no jpeg image produced by any digital camera is really โrawโ as it will already have been through a debayering filter https://en.wikipedia.org/wiki/Bayer_filter And then on top of that is the JPEG compression artifacts. But I do wonder how many raw files also contain data that has been debayered already. I have not looked into that. I know that with third party firmware such as Magic... - Source: Hacker News / about 3 years ago
Very niche (specific RAW video import tool), but the whole Magic Lantern's community wait for this kind of optimizations for years, so your guys can become real heroes :-). Source: about 3 years ago
If you shoot canon slap Magic Lantern on their and use zebra lines or focus peaking. Https://magiclantern.fm/. Source: about 3 years ago
