RepDB is a one-time-purchase exercise dataset for developers building fitness and workout apps — 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 512×512 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 — 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.

Blockchain features and specs

  • Security
    Blockchain provides strong security features, as each transaction is encrypted and linked to the previous one. This makes it highly resistant to fraud and hacking.
  • Transparency
    All transactions on the blockchain are publicly accessible and verifiable, which increases transparency and trust among users.
  • Decentralization
    Blockchain operates on a decentralized network, which reduces the reliance on a central authority and increases system robustness and uptime.
  • Immutability
    Once data is recorded on the blockchain, it cannot be altered or deleted, ensuring the integrity and consistency of the data over time.
  • Efficiency
    Blockchain can streamline and automate processes such as cross-border payments, reducing transaction times and costs.

Possible disadvantages of Blockchain

  • Scalability
    Blockchain networks often face issues with scalability, as the system can become slow and less efficient as the number of transactions increases.
  • Energy Consumption
    Blockchain, especially proof-of-work-based networks like Bitcoin, require substantial computational power, leading to high energy consumption.
  • Regulatory Uncertainty
    The legal and regulatory environment for blockchain technology is still evolving, which can create uncertainty and compliance challenges.
  • Complexity
    Implementing and maintaining a blockchain system can be complex and require specialized knowledge and skills, which might not be readily available.
  • Data Privacy
    While blockchain ensures transparency, it can also be a double-edged sword as the data is publicly accessible, posing privacy concerns for sensitive information.

Questions & Answers

As answered by people managing Blockchain and RepDB.

What makes your product unique?

RepDB's answer:

RepDB is sold as a one-time download, not a metered API — 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 — 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.

  • i lost over $3000 to blockchain.com
    I used blockchain.com back in 2015. I remembered back in the day they gave you a private key for all your addresses. Looks like they don't now with their newer wallets. Source: over 2 years ago
  • i lost over $3000 to blockchain.com
    In blockchain.com u dont actually own the address, you can access your account, but the address is all blockchain property, so they choose which address you have access to and so forth. Source: over 2 years ago
  • best crypto wallet app
    I use blockchain.com as the receiving wallet because they wallet address changes often and some of these ghetto ass sites don't let you withdrawal to the same one more than once. Source: over 2 years ago
  • Older wallet, higher fees?
    So says blockchain.com. Is it true, and if so is there a way to update/replace my Electrum wallet to pay lower fees in the future? Source: over 2 years ago
  • What is your thoughts on SOFI?
    This is anecdotal and I have no idea what it means for SOFI business wise or stock wise moving forward but they just sent me a notice that they are no longer offering any forms of crypto buying or investing and they are selling/giving their current crypto customers to blockchain.com in a few weeks.
