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 512ร—512 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.

Questions & Answers

As answered by people managing NextNative and RepDB.

Why should a person choose your product over its competitors?

NextNative's answer

Because it saves weeks of setup and thousands in development costs. While other tools force you to rebuild your app in another framework, NextNative keeps your existing Next.js codebase 100% intact. Itโ€™s built for developers who want native apps fast, not another learning curve.

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.

What makes your product unique?

NextNative's answer

NextNative is the only boilerplate that lets developers turn Next.js web apps into real iOS and Android apps, without learning React Native or Flutter. It combines Capacitor, Firebase Auth, RevenueCat, and Tailwind in a pre-configured setup, so you can go from code to App Store in a single day. No complex builds. No context switching. Just ship.

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.

How would you describe the primary audience of your product?

NextNative's answer

Web developers, indie hackers, and SaaS founders who already use Next.js and want to launch a mobile version of their product quickly. They value speed, simplicity, and control, not corporate frameworks or bloated SDKs.

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.

What's the story behind your product?

NextNative's answer

NextNative started as a personal pain point. After months of building SaaS products in Next.js, I realized that creating mobile versions meant starting from scratch with React Native or Flutter. So I built a solution for myself, a way to wrap my existing Next.js codebase into native apps using Capacitor. It worked so well that other devs started asking for it. Thatโ€™s how NextNative was born.

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.

Which are the primary technologies used for building your product?

  • Early adopters from indie SaaS and Next.js communities
  • Multiple small startups now shipping their apps to App Store and Google Play
