Every musician knows the moment: a melody arrives, you hum it into a voice memo, and it dies there. Earworm closes the gap — drop in any recording and get a clean, editable MIDI file for any DAW. HUM IT. GET MIDI. Record directly in the app, import a file, or share a Voice Memo straight in. Humming, singing, whistling, piano, guitar — one app for every instrument. Export standard MIDI that opens correctly in Logic, Ableton, FL Studio, GarageBand, Cubase, or any other DAW. EVERY NOTE COMPUTED ON YOUR IPHONE Nothing is ever uploaded. No account, no server, no internet connection required — try it in airplane mode. Privacy label: Data Not Collected. WRONG NOTES BECOME A SLIDER Transcription apps love to add notes that aren't there. Earworm keeps the full analysis on your device, so the sensitivity controls — onset threshold, note splitting, minimum note length — re-derive the whole result instantly as you drag. No re-processing, no waiting, no per-run charges. A REAL EDITOR, NOT JUST A CONVERTER Piano-roll editing with playback: delete, drag, resize, transpose, adjust velocity, undo. Audition the MIDI over your original recording to hear exactly where it lands. Pitch bends from slides and vibrato survive the round trip. Tap tempo, set BPM, and optionally quantize to a grid. ONE PRICE, FOREVER It runs on your iPhone. That's why we can charge once. Five complete transcriptions free — full length, full quality, full export, no watermark. Then a single lifetime purchase unlocks unlimited use, with Family Sharing included. No subscription. No tokens. No account. HONEST ABOUT LIMITS Earworm shines on melodies, vocals, and single instruments with simple polyphony. It is not built for full-band mixes or drums, and it is not a real-time effect. Files up to 10 minutes.
