iPhone

Sing one line. Pick the chorus on the waveform, and choir members made of your own voice stand there and sing with you — all on your device. Buy once, no subscription. A song sung alone always feels a little empty. Tutti is the choir that fills that space — with your own voice. ● Rehearsal — listen along the waveform, pick the chorus, and place choir members only there. How many stand (2·3·4), where they stand (above · both sides · below), how rich — and hear it on the spot. ● Performance — one button, start to finish: part split (voice and backing separated from the song), members join (harmony), settling (cleanup and mix), final polish (commercial tone and loudness). ● Recording cleanup — lifts room echo and noise from phone recordings (optional one-time download). ● Autotune — only when you want it, proudly audible (off = your voice as-is). ● Backing key — shift a song file's backing ±6 semitones, tempo intact. ● Green room — before/after comparison, sharing, per-song folders in Files. Your voice and your songs never leave this device. Free runs the whole show. Saving finished shows is two a month, and member/blend tuning — each member's level and placement, and the harmony amount, space and density — rides the rendered show on Full. Trying them in Rehearsal is free either way. Full is a one-time purchase, no subscription. Curious about your range? Our companion app Voxscope measures it in 40 seconds.

This release ships what was fixed after the last one but never reached your iPhone — and corrects five places where the app said something it didn't do. - Key suggestion now separates your voice first and measures that. It used to read the full mix, follow the low instruments, and on some songs land up to six semitones off. - That takes a moment, so it no longer runs by itself when you add a file — it runs when you tap "Measure with my range". Elapsed time is on screen while it works and Cancel really stops it. A song already measured isn't measured again — tap "Measure again" when you want a fresh reading. - When it can't tell, it says so — a different sentence for each reason, and it no longer states a cause it isn't sure of. - Fixed the opening and the middle being reported as "too different" when they sit on opposite sides of the tritone (six-semitone) boundary — the case that shows up when a man covers a woman's song. - Fixed "Key change only" losing 3.4 dB whenever tempo was changed too. Key-only exports sound exactly as before. - The cleanup models now come from a new primary host. If one host is down the next one takes over, and the app tells you it moved. - Storage is checked before the download starts; if there isn't enough, the app says how much is needed and how much you have. It's no longer blamed on the server, and a download that arrives but can't be prepared says so too. - Cancel now really lets go during the longest part of part splitting. - Measuring or moving a key keeps going if you leave the app — and if it does get cut off, the app says so. - Two heavy jobs no longer overlap: no key measuring while the cleanup models download, and vice versa (every locked control says why). - Leftover temporary files are cleaned up at launch too. - The Perform screen — where the button actually is — now says that harmony level, space and density aren't applied to the finished show on the free tier. - "Rehearse, or go straight on" offered two paths and went to one. The button that goes straight to Perform now exists. - "Use this key" now continues on the file you just made. It used to stack harmony on the original and shift the backing a second time. - Songs longer than 4:40 are told they'll be trimmed before it happens — along with the fact that you can choose which part goes on stage. - Fixed Korean words leaking into the "Blend" line in the English UI. - The in-app open-source notices now match what's actually in the app. - Small buttons have larger tap targets, and VoiceOver now reads progress and cancel while your key is being measured.
