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 250 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.

Possible disadvantages of Causal App

    The free version of Causal has limited features, which may not be sufficient for all needs. Advanced users might need to upgrade to a paid plan to access full functionality.
  • Dependency on Internet
    Causal is a cloud-based application, which means it requires a stable internet connection to operate. This could be a limitation in regions with inconsistent internet connectivity.

Questions & Answers

As answered by people managing Causal App 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.

  • Financial Statement APIs: What Most Accounting Platforms Won't Give You (and How to Get It Anyway)
    Financial planning tools are another major category. Causal, a financial planning platform, integrated with customers' accounting systems to pull financial statement data into an AI-powered modeling tool. Users connect their QuickBooks or Xero account, and the platform auto-generates financial models with metrics like burn rate and runway, updated on a recurring schedule. Cash flow data is especially valuable... - Source: dev.to / about 2 months ago
  • Ambsheets: Spreadsheets for Exploring Scenarios
    This is exactly what I loved about the Causal app (no affiliation). They started as a general purpose spreadsheet with 'Amb' cells built-in, though later on they seem to have converged on the financial modeling space. [0]: https://causal.app/. - Source: Hacker News / over 1 year ago
  • Ask HN: Alternative to Causal for probabilistic spreadsheet models
    It looks like Causal (https://causal.app) has pivoted to focus on businesses. There are a lot use cases for individual users to build models with probabilistic parameters that are no longer possible due to the high cost (example: https://netlify.causal.app/buy). Is there another spreadsheet + probabilistic model parameter tool available for individual users? - Source: Hacker News / almost 2 years ago
  • My Thoughts on Python in Excel
    IMO the better paradigm is coming from enterprise applications like Anaplan. Cells are not the right abstraction to work with numbers. Most of the time you work with multi-dimensional quantities (eg revenue by product, geography, month). Weโ€™re working on a more approachable implementation of that paradigm at https://causal.app. - Source: Hacker News / about 2 years ago
  • Show HN: Type-safe feature flags with Git versioning, local fallbacks, GraphQL
    We're using Hypertune at https://causal.app for a few months now and it's been great! We have a few feature flags in there but also some more complex typed data for our onboarding modals. - Source: Hacker News / about 3 years ago
