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.

RepDBWeb2Android's answer
Web2Android focuses on the fastest path from an existing website or HTML to a real, Play Storeโready Android app with full ownership.
Unlike many app builders, it produces white-label APKs with no forced branding or revenue share, while giving users full control over AdMob monetization, app icons, splash screens, and native behaviors.
It is designed for indie developers, side-hustlers, and small businesses who want a simple, no-code solution without learning complex app builders or frameworks.
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.
Web2Android's answer
Web2Android is a better choice for users who already have a website or HTML and want the simplest way to turn it into a real Android app without rebuilding everything from scratch.
Compared to many competitors, it offers full ownership of the APK, no forced branding or revenue sharing, and direct control over AdMob monetization. Users can customize core app elements such as icons, splash screens, and navigation while keeping the workflow straightforward.
It is especially suitable for indie developers, side-hustlers, and small businesses who want speed, simplicity, and control rather than learning complex no-code or low-code app builders.
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.
Web2Android's answer
Web2Android is designed primarily for indie developers, side-hustlers, bloggers, and small businesses who already have a website or static HTML and want to turn it into an Android app.
The platform is well suited for users who want a no-code, straightforward solution without learning complex app builders, while still retaining control over branding, monetization, and app ownership.
It is especially useful for individuals and small teams looking to publish Android apps quickly and manage them independently.
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.
Web2Android's answer
Web2Android is built using a modern web and Android-focused technology stack.
The platform uses a web-based frontend for configuration and app generation, combined with an automated Android build pipeline based on native Android tooling. Under the hood, it relies on Android WebView for rendering websites, Gradle-based Android builds for APK generation, and AdMob SDK integration for monetization.
Server-side services handle build orchestration, customization, and asset management, while cloud infrastructure is used to queue builds and deliver Play Storeโready APK files efficiently.
Web2Android's answer
Web2Android's answer
Web2Android was built by a solo, non-coder founder who faced the same problem many creators do: turning an existing website into an Android app was slow, expensive, or overly restrictive.
Instead of choosing between complex native development or limited no-code tools, Web2Android was created to offer a simpler alternative โ convert any website or HTML project into a real, Play Storeโready Android app without writing code.
Designed from firsthand experience, the platform gives users full control over branding, monetization, and ownership, with features like AdMob integration, push notifications, and custom app assets โ so creators can ship Android apps quickly and independently.
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.
