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 ConvertPK and RepDB.

What makes your product unique?

ConvertPK's answer

ConvertProKit is a privacy-focused online toolkit that works entirely in the browser. Users can convert images, work with PDFs, generate QR codes, use calculators, and access productivity tools without creating an account or installing software. The platform focuses on speed, simplicity, and ease of use.

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.

Why should a person choose your product over its competitors?

ConvertPK's answer

ConvertProKit offers a clean, fast, and user-friendly experience with a growing collection of free online tools in one place. It prioritizes browser-based processing whenever possible, requires no sign-up, and is designed to help users complete everyday tasks quickly and efficiently.

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.

How would you describe the primary audience of your product?

ConvertPK's answer

ConvertProKit is built for students, professionals, developers, designers, content creators, businesses, and anyone looking for fast, reliable online utilities for everyday work.

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?

ConvertPK's answer

ConvertProKit was created to simplify common digital tasks by bringing useful online tools together in a single platform. The goal is to provide fast, accessible, and easy-to-use utilities that save time without requiring software installation or complicated workflows.

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?

ConvertPK's answer

Modern HTML5, CSS3, JavaScript, browser APIs, responsive web technologies, and secure cloud infrastructure are used to deliver a fast and reliable experience across desktop and mobile devices.

Who are some of the biggest customers of your product?

ConvertPK's answer

ConvertProKit is used by a broad range of individuals and small teams worldwide, including students, freelancers, developers, designers, educators, marketers, and small businesses.
