Topline

Voice memos for songwriters · iPhone

Get it down before it disappears.

Hum a melody, sing a line, strum an idea. Topline saves it the moment you stop, turns it into lyrics you can search, and lets you record the next take over the chords you meant.

Made for the first two minutes of a song

Record first. Decide what it is later.

Most song ideas arrive when you are nowhere near a studio. Topline is built for that moment, and it stays out of the way once the idea is safe.

Nothing between you and record

The record button is pinned to the bottom of the screen where your thumb already is. Tap, sing, tap. The take is saved with the time it was captured.

  • Full-bandwidth 44.1 kHz audio, so guitar and voice sound like they did in the room
  • Hands-free with Siri: “Hey Siri, start a Topline recording”
  • Keeps recording in the background

Lyrics that write themselves

Every recording is transcribed on your phone into a lyric sheet. Search any line you sang, even weeks later, when all you remember is one word.

  • Fix a misheard word with a tap
  • Swap a word for a rhyme or a near-rhyme without leaving the sheet
  • Turn transcription off in Settings if you only capture melodies

Chords when you want them

Attach a chord progression or a backing track and record over it. Engage or silence either layer for the next take without losing your place.

  • Piano and Rhodes voicings, drone, metronome, tempo, time signature
  • Import your own backing track and set where it starts
  • Nashville numbers throughout, so a progression moves with the key

Lyrics

Your mumble, on paper.

Topline listens back to the take and writes down what it heard. Tap any word to correct it, or to pull up rhymes and synonyms from a dictionary built for songwriting. The edit history stays with the recording, so the first draft is never lost.

Try it on the sheet: tap a word, pick a rhyme, then undo.

Search covers titles and every line of every lyric sheet. Type “porch light” and the chorus from three weeks ago comes straight back.

Music layer · optional

A backing band that fits in the key.

Pick a key and Topline lays out its seven chords, labeled with Nashville numbers. Tap them into a progression, hear it loop, then record over it. Change the key later and the progression moves with you.
