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.

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.

Wait til you get to CS-330 I'm taking it rn, definitely the hardest class I've ever taken. Also, with that many readings, consider using naturalreaders.com That's what I use for the majority of the readings, I set the WPM at like 230 or so and just follow along, because I read incredibly slow, but can understand it and get through it way faster if I listen to it. This resource has saved me a ton of time so far! Source: about 4 years ago
Invest in software like naturalreaders.com that will read your assignments out loud. I'm sure there are better versions than this, but it's the one I use. It lets you set the speed and follow along, which is helps SO MUCH when you're dealing with dry boring material. You can even put your class notes in there and it will read them out loud to help you with memorization. Source: over 4 years ago
I wrote my entire explanation of WHY I am having them do the assignment. Please note that I also included a link to naturalreaders.com and told them that because this was so important that if they had trouble reading long text (and these instructions are not that long) to use the text-to-speech function.

TL = target language, in your case, Spanish. I've been doing a lot of L-R--but as Ryan says, just with Spanish text/audio. I can recommend these sites: openlibrary.org (free to sign up for/use), librosdemario, holaebook, and lelibros.online. I then use the Google Read&Write extension to read the text to me if it's online or naturalreaders.com if it's a download. Good luck! Source: about 5 years ago
