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.

InboxZero features and specs

  • Increased Productivity
    InboxZero encourages immediate action on new emails, leading to a more organized workflow and preventing accumulation of unread messages, which can boost productivity.
  • Reduced Stress
    Keeping an empty inbox reduces the overwhelming feeling that can come from seeing a large number of unread emails, which can help decrease stress and anxiety.
  • Improved Focus
    By handling emails as they arrive or scheduling set times to process them, individuals can dedicate more focused attention to other tasks without the distraction of a cluttered inbox.
  • Better Email Management
    Regularly organizing and archiving emails keeps the inbox tidy and ensures important messages are not lost among less urgent ones.

Possible disadvantages of InboxZero

  • Time-Consuming
    Maintaining an empty inbox requires constant attention and can be time-consuming, especially for those receiving a large number of emails daily.
  • Potential for Decreased Efficiency
    Focusing too much on achieving InboxZero can lead to spending unnecessary time on less important emails, detracting from more critical tasks.
  • Pressure and Anxiety
    The need to maintain an empty inbox can add pressure and anxiety, particularly if it's deemed unmanageable due to external factors such as the volume of incoming emails.
  • Negative Impact on Work-Life Balance
    The requirement to continuously check and manage emails to maintain InboxZero can lead to work encroaching into personal time, potentially impacting work-life balance.

Questions & Answers

As answered by people managing InboxZero 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.
