RepDB
6th Mind is a free mental health app that brings clinically-validated therapy to your smartphone. Using AVE (Audio-Visual Entrainment) technology - a combination of stroboscopic light and isochronic tones - the app helps users manage depression, anxiety, insomnia, and burnout.

Key Features:
Who It's For:
Unlike meditation apps, 6th Mind uses active brain stimulation techniques validated through hundreds of clinical sessions. It can be used alongside traditional therapy and medication.
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 250 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.

RepDB6th Mind's answer
6th Mind is the only mental health app built from a real clinical practice with 500+ therapy sessions and 80%+ patient success rate. Unlike meditation apps, it uses clinically-validated AVE (Audio-Visual Entrainment) therapy developed by a psychiatrist and psychologist team. Our proprietary EEG Indexโข methodology - based on actual brain activity measurements from patients - enables personalized treatment protocols with measurable outcomes, not just subjective "feel better" results.
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.
6th Mind's answer
vs. Meditation apps (Headspace, Calm):
Active brain stimulation therapy vs passive meditation
Clinical validation (500+ sessions, 80%+ success) vs lifestyle wellness
Evidence-based protocols vs general relaxation
100% free vs $12-15/month
vs. AVE apps (Lumenate):
Clinical focus (treating depression/anxiety) vs recreational (psychedelic experience)
Backed by real clinical practice with measurable patient outcomes
Personalized 15-day protocols based on assessment vs open exploration
Developed specifically for mental health treatment, not entertainment
vs. Therapy:
Free and accessible 24/7 vs expensive and scheduled
Can be used alongside traditional therapy as complementary support
Based on protocols proven effective in clinical practice
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.
6th Mind's answer
Our primary audience is people aged 25-55 struggling with depression, anxiety, insomnia, or burnout who are:
Seeking science-backed, non-invasive mental health solutions
Looking for affordable or free alternatives to expensive therapy
Open to technology-based approaches to mental wellness
Interested in evidence-based methods with measurable results
Wanting complementary tools to use alongside (or instead of) medication and traditional therapy
Secondary audiences include tech professionals and entrepreneurs dealing with burnout, and anyone who prefers medication-free approaches to mental health.
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.
6th Mind's answer
6th Mind was born from our clinical mental health practice in Sofia, Bulgaria. After treating 500+ patients for depression, anxiety, and burnout over 18 months with 80%+ success rate using AVE (Audio-Visual Entrainment) therapy, we realized something powerful: the same protocols that worked in our clinic could potentially work through a smartphone.
We saw that effective mental health therapy was inaccessible to most people - either too expensive, geographically limited, or required special equipment. Our psychiatrist and psychologist team spent months analyzing data from hundreds of clinical sessions to develop personalized protocols that could be delivered via any smartphone's camera flash and speakers.
Our mission is simple: make clinically-proven mental health therapy accessible to everyone, everywhere, for free. The app brings our clinical expertise into your pocket, transforming your phone into a therapeutic device backed by real clinical data, not just wellness trends.
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.

6th Mind's answer
As a B2C mental health app focused on individual users, we serve thousands of people rather than traditional "enterprise customers". However, our user base includes:
Individual users seeking free mental health support (current primary focus)
Indie makers and solopreneurs dealing with burnout
Tech professionals and developers experiencing work-related stress
People who have tried medication or therapy but seek complementary approaches
Future B2B partnerships in development:
Corporate wellness programs (employers seeking mental health solutions for employees)
Psychologists and psychiatrists (using the app as between-session support for their patients)
Universities and counseling centers (providing accessible mental health tools for students)
Note: We're currently B2C-focused with a free app. Our "biggest customers" are the hundreds of individuals who complete our 15-day protocol and see measurable improvements in their mental health. We're building toward B2B partnerships but haven't launched enterprise offerings yet.
the app is actually good and its features but will have to use more
