Your Move App
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.
HEYWITHIN
RepDBHEYWITHIN's answer
HEYWITHIN is an AI-powered personal understanding and growth platform built around deep, guided conversations. Instead of giving users a personality score or generic AI advice, HEYWITHIN explores the connections between their experiences, relationships, decisions, fears, goals, and ambitions.
The system uses follow-up questions to validate emerging patterns and, when there is enough evidence, turns those patterns into new discoveries and personalized growth directions. The result is an evolving understanding of the individual rather than a one-time assessment
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.
HEYWITHIN's answer
HEYWITHIN started with a simple observation: people have more access to information and advice than ever before, yet many still struggle to understand themselves and make decisions with clarity.
The founder's background across business development, sales, real estate, and construction meant working with people making important career, financial, and life decisions. A recurring pattern became clear: the problem was often not a lack of information, but a lack of understanding of the person behind the decision.
As conversational AI became increasingly natural, a new possibility emerged: what if AI could do more than answer questions and instead have a structured conversation designed to help someone discover their own patterns?
That became HEYWITHIN — an attempt to combine conversational AI, life-coaching principles, and continuous personal growth into one experience.
The long-term vision is to create a personal understanding system that becomes more useful as it learns, through conversation, what matters to each individual.
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.
HEYWITHIN's answer
HEYWITHIN is designed for people who don't simply want answers — they want to understand themselves.
General AI assistants can answer almost anything, but they are not specifically designed around structured self-discovery. Personality tests provide snapshots, while traditional coaching can be expensive and difficult to access consistently.
HEYWITHIN combines the accessibility of AI conversation with the structure of life coaching and a layer of psychological awareness in the background. It helps users explore why they think, feel, decide, and behave the way they do, then uses those insights to guide their next area of growth.
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.
HEYWITHIN's answer
HEYWITHIN is designed primarily for adults who feel stuck, overwhelmed, uncertain, or at a transition point in their lives and want greater clarity about themselves and their future.
This includes people exploring career decisions, relationships, personal goals, financial ambitions, life direction, or recurring patterns in their behavior.
It is particularly suited to people who are comfortable talking to AI but want something deeper and more structured than a general-purpose chatbot.
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.
HEYWITHIN's answer
HEYWITHIN is currently in its early launch and product-validation stage. We are focused on building our initial user base and validating product-market fit. No major enterprise customers yet
HEYWITHIN's answer
HEYWITHIN is built using modern web and AI technologies, including:
Next.js and TypeScript for the application Anthropic Claude for conversational AI and reasoning Supabase for database, authentication, and backend infrastructure Vercel for deployment and application infrastructure Stripe for subscription and payment infrastructure
The architecture is designed to support long-form AI conversations, persistent user context, personalized discoveries, and an evolving personal Life Blueprint.
