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.
Most health apps ignore prostate and sexual health entirely. ManCore fills that gap โ daily symptom logging, automatic IPSS/SHIM clinical scoring, supplement tracking, and screening reminders, all free. Built for men who want data before their next urologist visit instead of guessing. SaaS-style subscription (Pro tier) adds advanced trend analytics and full-history PDF export; the core tracker stays free permanently
RepDB ManCoreRepDB'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.
ManCore's answer:
ManCore combines daily health tracking with real clinical instruments most consumer apps skip โ IPSS and SHIM/IIEF-5 scores are calculated automatically, not just logged as free text. Every article is medically reviewed and PubMed-cited. No supplements are sold on the platform, so there's no incentive to oversell any product or claim.
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.
ManCore's answer:
Prostate and sexual health tracking simply didn't exist as a real app category โ fitness apps cover steps and sleep, but the symptoms men actually start worrying about after 40 (urinary frequency, PSA trends, erectile function) had no dedicated home besides a paper diary or a spreadsheet. ManCore was built to fill that gap, with medically-reviewed content and cited research built in from day one rather than added later.
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.
ManCore's answer:
General fitness apps (Apple Health, MyFitnessPal) don't track prostate, urinary, or sexual-function symptoms at all. A paper diary or spreadsheet doesn't auto-calculate clinical scores or send age-based screening reminders. ManCore does both, for free, and exports a doctor-ready PDF report โ most alternatives solve one piece of the workflow, not the full loop from daily symptom to urologist visit.
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.
ManCore's answer:
Men 40 and older managing or at risk of prostate issues (BPH, early urinary symptoms) and related sexual health concerns like erectile dysfunction. Typically health-conscious, often pre-diagnosis or newly diagnosed, wanting objective data before or between urologist visits.
