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.

MacroFactor features and specs

  • Adaptive Nutrition Coaching
    MacroFactor uses a sophisticated algorithm that continuously adjusts your calorie and macro targets based on your actual weight trend and intake data, rather than relying on static estimates. This means your nutrition plan evolves with you over time for more accurate results.
  • Comprehensive Food Database
    The app features a large, verified food database with over 1.4 million entries, making it easy to log meals accurately. It also supports barcode scanning and custom food/recipe creation for convenient tracking.
  • Flexible Dietary Approaches
    MacroFactor supports a wide range of dietary styles and goal types, including collaborative mode (where it sets macros for you), coached mode, and manual mode. Users can customize macro ratios, set different targets for different days, and adjust goals easily.
  • Clean, Ad-Free Experience
    The app is completely free of advertisements, which provides a clean and distraction-free user experience. The business model is subscription-based, so users are treated as customers rather than products.
  • Expenditure Tracking and Analytics
    MacroFactor calculates your total daily energy expenditure (TDEE) based on your real-world data rather than generic formulas. It provides detailed analytics dashboards showing trends in weight, nutrition, and expenditure over time, giving users deep insight into their progress.

Possible disadvantages of MacroFactor

  • Subscription Cost
    MacroFactor requires a paid subscription to use (after a free trial period), which can feel expensive compared to free calorie-tracking apps like MyFitnessPal or Cronometer's free tier. This may be a barrier for budget-conscious users.
  • Learning Curve
    The app's advanced features, multiple coaching modes, and detailed analytics can be overwhelming for beginners or those who just want simple calorie counting. It takes time to understand how the algorithm works and how to best use the various settings.
  • No Free Tier
    Unlike some competitors that offer a functional free version with optional premium upgrades, MacroFactor does not have a permanent free tier. Once the trial expires, users must subscribe or lose access entirely.
  • Limited Social and Community Features
    MacroFactor focuses heavily on individual tracking and coaching but lacks built-in social features like friend challenges, community forums, or sharing capabilities that some users find motivating in other fitness apps.
  • Requires Consistent Logging for Best Results
    The adaptive algorithm depends on consistent and accurate food logging and regular weigh-ins to function optimally. If users log sporadically or inaccurately, the algorithm's recommendations become less reliable, which can frustrate inconsistent trackers.

Questions & Answers

As answered by people managing RepDB and MacroFactor.

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.
