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 400 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.

VidaiMock features and specs

AI-Powered Mock Interviews
VidaiMock leverages artificial intelligence to simulate realistic interview scenarios, allowing candidates to practice and prepare for job interviews in a safe, low-pressure environment without needing a human interviewer.
Convenient and Accessible
As a web-based platform, VidaiMock allows users to practice mock interviews anytime and anywhere with an internet connection, removing the need to schedule sessions with career coaches or peers.
Personalized Feedback
The platform provides AI-driven feedback on interview performance, helping users identify areas of improvement such as communication skills, answer quality, and confidence levels.
Cost-Effective Interview Preparation
Compared to hiring professional interview coaches or attending in-person workshops, VidaiMock offers a more affordable way to prepare for interviews, making quality preparation accessible to a wider audience.
Repetitive Practice Without Judgment
Users can repeat mock interviews as many times as they wish without feeling judged, which helps build confidence and refine responses over time through iterative practice.

Possible disadvantages of VidaiMock

Limited Human Nuance
AI-generated feedback may lack the nuanced understanding and emotional intelligence that a human interviewer or career coach can provide, potentially missing subtle aspects of body language or tone.
Limited Public Information
The platform appears to have limited publicly available reviews and detailed documentation, making it harder for potential users to evaluate the tool's effectiveness before committing to it.
May Not Cover All Industries
The AI mock interview scenarios may not adequately cover niche or highly specialized industries, potentially leaving some candidates without relevant practice for their specific field.
Internet Dependency
Being a web-based platform, VidaiMock requires a stable internet connection and functioning webcam/microphone setup, which could be a barrier for users with limited or unreliable connectivity.
Cannot Fully Replicate Real Interview Pressure
Despite being a useful practice tool, a virtual AI mock interview cannot fully replicate the stress, dynamics, and unpredictability of a real face-to-face interview with a human interviewer.

While it can be a useful tool for interview preparation, you should verify its current features, pricing, and reviews directly, as I don't have confirmed independent data on its performance and reliability.

Questions & Answers

As answered by people managing VidaiMock 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.
