iPhone
Hum a few notes to find the melody you saved three weeks ago. Fully offline: no account, no ads, nothing ever uploaded.
Half a melody in your head and afraid to lose it? Open the app, one tap, it's saved.
Linggan Box is an inspiration vault for songwriters. The tune that came while driving, the line that arrived at 2 a.m. — catch it first, sort it out later.
ONE TAP TO RECORD
Lock Screen widget, Control Center, Siri, and the Action button all start recording in one step — no unlocking and hunting for the app. Say "记个灵感" to Siri and recording begins. Lock the screen mid-take and it keeps recording until you stop it.
HUM TO FIND IT AGAIN
Once you have dozens of ideas, titles stop helping — you remember the melody, not what you called it. Tap "Hum to find", hum the line again, and your inbox re-sorts by melodic similarity, closest match first. A different key, a faster or slower take, even a half-remembered version still matches.
SEE THE MELODY
Expand any clip to see its pitch curve — exactly which notes you hummed and how wide the range was. All pitch analysis runs on your phone. Nothing is uploaded.
YOUR DATA IS YOURS
No servers, no accounts, no ads, no analytics, no network access at all. Recordings live only on this device — not because our privacy policy says so, but because this app physically cannot upload them.
NEVER LOSE AN IDEA
One-tap backup packs every recording into a single file — safe from accidental deletion and phone upgrades. Renames are written to disk immediately, so nothing is lost even if the system reclaims the app.
Free. No ads. No in-app purchases. Nothing leaves your phone.
