RepDB
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 512ร512 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.
ActivityWatch
RepDBActivityWatch is recommended for remote workers, freelancers, productivity enthusiasts, and anyone looking to gain a deeper understanding of their computer usage patterns without compromising on privacy. It is also suitable for developers and tech-savvy users who want to customize or extend its functionality.
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.
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.
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.
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.

Hi HN. RewindOS captures your screen every few seconds, OCRs it, and makes everything you've ever seen instantly searchable โ all 100% local. No cloud, no account, no telemetry. MIT-licensed, and built specifically for Linux/Wayland. I started out using [ActivityWatch](https://activitywatch.net/), which is great at what it does โ but it tracks how much time you spend in each app, not what you actually... - Source: Hacker News / about 2 months ago
Ah okay. I think this would probably be pretty tricky, security-wise, no? One of my first thoughts that might help would be writing a simple tool that parses history from your browsers to categorize it. Other than that, there are things like https://activitywatch.net/ (which seems to have a desktop and Android version). - Source: Hacker News / 8 months ago
It's an actual useful feature, it's just the tracking by microsoft that makes it meh. I also track my activities with ActivityWatch (Open Source, https://activitywatch.net/) to remember missing time entries for billing clients. It's all local, so perfectly fine. - Source: Hacker News / 10 months ago

> How hard would it be for an app to monitor all of your web traffic based on the title alone? Although not terribly accurate (because of the high variability of page titles), tools like ManicTime and ActivityWatch use windows titles to track your browser history if you don't install the browser plugin. https://www.manictime.com/ https://activitywatch.net/. - Source: Hacker News / over 1 year ago
