Stage Player 
Chord Analyser 
Am I Happy? Whether you're a seasoned performer or an enthusiastic learner, our music applications cover the gaps that most apps overlook - with ergonomics and reliability at their core.
An interactive reverse chord dictionary for Piano, Guitar, Banjo and more. Press notes, get the chord - or pick from 3,500+ chords and discover every playable position on your instrument.
A professional-grade MP3 player engineered for live performance. Manage backing tracks, sound effects, and sequences with the reliability and simplicity you need when you're on stage.
Beyond music, we build apps that help people understand themselves better. Am I Happy? is a daily wellbeing tracker based on the science of memory and emotion.
Your brain rewrites your memories. Studies in cognitive psychology show that retrospective happiness evaluation is systematically distorted by emotion and time. Am I Happy? solves this by capturing how you feel right now - every day, in under a minute.
Visual charts of your happiness evolution by day, week and month.
Track what matters to you: sleep, sport, work, relationships.
No name, no email required. Your data is yours, stored securely on AWS.
We build applications that cover genuine, often overlooked needs. But beyond solving real problems, we have a clear set of principles about how we build them.
The mobile industry has normalized dark patterns: addictive mechanics, guilt-driven notifications, data exploitation, aggressive upsells. We reject all of that.
When we do offer a premium tier, it's because some features have real infrastructure costs - cloud storage, AI processing. That's the only reason they're paid. No pressure, no manipulation.
Work with usNo banners, no trackers, no data sold to advertisers. Your attention belongs to you.
No streaks, no badges, no guilt notifications. No mechanics engineered to manufacture dependency.
The vast majority of each app is free. Premium exists only where there's a genuine cost to cover.
If a feature costs money, we tell you why: cloud storage, AI processing. No arbitrary paywalls.
We collect only what's strictly necessary. Your data is yours. No profiling, no exploitation.
One app, one real problem. No feature bloat, no distraction from what actually matters.
Explore every option for triggering backing tracks live - from dedicated hardware to smartphone apps - and find the right setup for your performance style.
