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 Undo App and RepDB.

What makes your product unique?

Undo App's answer

Undo meditation app is loaded with insightful content that resonates with your body and makes complete sense. Easy to follow educational course, a proprietary tool that reconnects your body and mind, transformative healing meditations to supercharge your recovery.

Learn to feel with meditation thatโ€™s easy Your feelings determine your thinking and feelings come from your body. Undo meditation is anchored in your body. Powerful meditation with lasting impact. No techniques or dogma. Free yourself from overthinking and return to your optimal state.

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.

What's the story behind your product?

Undo App's answer

Undo was created in response to the deteriorating quality of meditation in the market. As experts in our field, we aim to set a higher standard in the industry. We can confidently say that we are the only meditation app that doesnโ€™t use a meditation technique or dogma.

Meditation for beginners and seasoned alike, itโ€™s easy for anyone to make sense of this approach. By stimulating the wisdom already present in your body it automatically integrates into your life. Undo ties up all your loose ends. Unanswered questions are completed. Inside of you, it feels like the final piece of the puzzle has been found and set in place, or like youโ€™ve finally been heard and understood.

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.

Why should a person choose your product over its competitors?

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?

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.
