Four real options in one table: who each is for, where your music goes, and what each one will not do. I make the last of the four, so read the column it is in with that in mind. Everything in the other three columns comes from their own sites and listings.
| Who it is for | Musicians learning a part | Producers and remixers | One song, nothing installed | Singers, on songs they own |
|---|---|---|---|---|
| Where the work happens | Their servers | Its listing does not say | Their servers | Your phone |
| Works with no signal | No | Not stated | No | Yes |
| The limit | Free tier is capped | Free, with purchases inside | 10 free minutes, then packs | None |
| What you get back | Vocals, drums, bass, guitar, keys and twenty more | Vocals, drums, bass, guitar | Vocals, drums, bass, guitar, piano and more | The voice and everything else |
| Change the key | Yes, up to twelve semitones | No | No | Yes |
| Change the speed | Yes | Yes | No | No |
| Find the chords | Yes | No | No | No |
| Words in time with the music | Transcribes them | No | No | Looked up, scrolling as you sing |
| Your own vocal range | No | No | No | Measured, and checked against a song |
| Keeps your takes | Records performances | No | No | Every take kept |
| Runs on | Web, desktop, iPhone, iPad, Android | iPhone and iPad | Web, desktop, iOS, Android, VST | iPhone |
Checked on 14 September 2026 against each product's own site, help centre and App Store listing, and a "no" means the feature is not in the list the product publishes. Moises' pricing table sits behind a login, so no prices are quoted. Features move: if the decision matters, check theirs rather than trusting a table on a competitor's site. Each name and icon belongs to its owner and is used to say which product is being discussed.
The App Store carries dozens more vocal removers beyond these and most of them are much the same as each other. The row worth reading before you pick one is the second.
Worth saying before the button at the bottom. All four are reasonable choices and mine is the narrowest of them.
What you get for that: nothing uploaded, about twenty seconds a song with the network switched off, the words in time, the key moved to suit you, and every take kept so you can hear the same song again a month later.
On the App Store, for any iPhone running iOS 17 or later. No account, no upload limit, and nothing leaves the device.
