About

MUEDnote

Read full description

MUEDnote is an app that understands how you think about music. You don't have to write anything. Through conversations with Hoo, an AI owl companion, MUEDnote reads your production style, strengths, and the challenges on your mind — then organizes it all into a profile, automatically. The note isn't something you write. It's something written about you. --- Key Features --- [Profile Dashboard] Hoo auto-generates your profile as a music creator from your conversations and session data. View and edit your production tendencies, focus areas, and musical decision-making patterns in card format. [Conversations with Hoo] Hoo is an owl-shaped AI partner. Hoo listens, nods along, and surfaces creative patterns you didn't know you had. [Hoo's Care] Pomodoro-based focus management. After a 50-minute session, Hoo reminds you to take a break. Not overworking — that's Hoo's job too. --- MUEDnote has changed --- In v1.1.0, MUEDnote evolved from a "production log app" into an app that knows you. We removed manual log input entirely, replacing it with a natural conversation-based approach to building your profile. And it's now completely free. No subscription required.

ChordFrog trains your ear to recognise chords by sound — no instrument or extra gear required. Play audio quizzes anywhere, then connect a MIDI keyboard (USB or Bluetooth) whenever you want hands-on practice on real keys. PRACTICE MODES • Leap Quiz — no keyboard needed. Multiple-choice ear training you can do anywhere — on the bus, in a waiting room, whenever you have a few minutes. • Travel Chords — no keyboard needed. An audio chord reference library; tap any chord to hear it. • Challenge — no keyboard needed. Pick up to three chords and ChordFrog builds a short video that plays them, counts down, then reveals the answer. Share it anywhere, or leave it on a cliffhanger and let your friends guess. • My Pond — no keyboard needed. Every chord you have practised, weakest first, with one tap to drill the ones you keep missing. • Lily Pad Drill — with a MIDI keyboard. 10-question scored rounds with up to 100 points. Three tries per chord, so every attempt counts. • Free Pond — with a MIDI keyboard. Play freely and ChordFrog names every chord in real time, including inversions and slash chords. A MIDI keyboard is optional: four of the six modes work entirely on their own, while Lily Pad Drill and Free Pond add hands-on practice when you connect one. SIRI AND SHORTCUTS Ask for a chord and hear it without opening the app — useful when you are already reading a chart. Shortcuts can also identify a chord from its notes, list the chords you find hardest, and start a drill on them. LEVELS Progress through five stages from beginner to advanced: • The Campfire — the most common chords in pop and folk music • The Session — all 12 major and minor chords • The Gig — dominant 7th and major 7th chords • The Studio — minor 7th, sus2, and sus4 chords • The Abyss — everything: diminished, augmented, 7ths, 6ths, and more CHORD VOCABULARY Recognises major, minor, diminished, augmented, sus2, sus4, dominant 7th, major 7th, minor 7th, half-diminished, 6th and add9 chords, including inversions and slash chords. Free Pond also names extended and altered voicings — 9th, major 9th, minor 9th, 13th, minor 11th and altered dominants — and it reads a seventh chord voiced without its fifth, the way players actually voice one. FREE, WITH ONE OPTIONAL PURCHASE ChordFrog is free and nothing is gated. It is supported by a banner on the menu and one full-screen ad after a completed round; a single Remove Ads purchase takes both away if you would rather not see them. Designed for pianists, guitarists, singers, producers, and songwriters who want sharper ears.
