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 one sec and RepDB.

What makes your product unique?

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?

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.

  • Finland to end "uncontrolled human experiment" with ban on youth social media
    I think most users need more screen blocking control than they get out of the box on iOS. Ntools like one sec [1] have been invaluable for me. [1]: https://one-sec.app/. - Source: Hacker News / 6 months ago
  • Using an $8 smart outlet to avoid brainrot
    One thing that finally worked for me was using: https://one-sec.app/ It basically forces you to do a little breathing exercise before you can visit the site that you have on its block list. It has been life changing. It adds enough frictions for me to stop any impulsive visits but also is not so annoying that I would completely disable it in a weak moment. One Sec was developed by someone with ADHD, I think and it... - Source: Hacker News / about 1 year ago
  • My Struggle with Doom Scrolling
    I've tried various forms of this. As long as there's a logged in session somewhere, I have to have various tricks and extensions on my browser to manage things. Most have been only varying degrees of successful, often ending up in me just disabling the feature whenever I want to get my fix. The most successful iteration I've found so far is keeping these apps uninstalled from my phone, and using... - Source: Hacker News / over 1 year ago

  • TinyPod โ€“ Apple Watch case with scroll wheel
    I actually really like this concept. Recently, I added OneSec (https://one-sec.app/) to most of the apps I use to create some type of friction. It works great on the apps I added it to, but the addiction is so real that I find myself doom-scrolling on apps I rarely use, such as LinkedIn. - Source: Hacker News / about 2 years ago
