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.
NativeBase 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.

Gluestack, like any other customizable UI library, is built to make styling less cumbersome. It comprises a set of themed and unstyled components easily integrated across different platforms and devices. Originally, Gluestack was a part of NativeBase, a component library for both React and React Native. With performance and maintainability in mind, NativeBase was split into two parts, focusing on a universal... - Source: dev.to / over 2 years ago
Just like the other libraries mentioned in this article, Gluestack is another unstyled component library. Originally a part of NativeBase, the developer team created this library to prevent bloat and enhance maintainability of the project. - Source: dev.to / almost 3 years ago
KumaUI : Another relatively new contender, Kuma uses zero runtime CSS-in-JS to create headless UI components which allows a lot of flexibility. It was heavily inspired by other zero runtime CSS-in-JS solutions such as PandaCSS, Vanilla Extract, and Linaria, as well as by Styled System, ChakraUI, and Native Base. ### ๏ปฟVue. - Source: dev.to / almost 3 years ago
NativeBase is a collection of essential cross-platform React Native components. The components are built with React Native combined with some JavaScript functionality with customizable properties. NativeBase is fully open-source and has 18,000+ stars on GitHub. - Source: dev.to / over 3 years ago
CSS-based UI libs don't make sense on mobile; your new options include NativeBase, React Native Elements and others). Some web-based UI libs do have RN siblings though - such as React Native Material and React Native Paper (for Material-UI), and tailwind-rn (for Tailwind). This just means new decisions to make, some learning, and new paradigms for how to use the new libs. - Source: dev.to / over 3 years ago
