Riftone vs Moises: Which Stem Splitter App for iPhone?
Both apps use AI to split a song into stems so you can remove vocals, isolate drums or mute an instrument to play along. Moises is the larger, older and more complete platform. Riftone is a simpler iPhone-only app that always gives you six stems.

We have not run a blind audio-quality test of the two separation engines, so this page makes no claim about which sounds cleaner. Both are AI separators: expect some bleed between stems on dense mixes.

Which one should you pick?
Singer making karaoke tracks occasionally
Start with the Moises free plan: five songs a month, vocals vs instrumental, is often enough. If you need more songs, the key changed and WAV export on your phone, try Riftone's weekly trial.
Guitarist or pianist practicing along
Riftone splits guitar and piano out in every song, so you can mute your part and keep the band. Moises Premium can do this too if you pick those instruments when uploading, and adds chord charts, which many players value.
Producer or heavy user
Moises: longer files, finer instrument options, desktop app and DAW plugin, and Pro features. Riftone is built for quick work on the iPhone, not a studio workflow.
Free to download. Weekly plan includes a 3-day free trial.

Which has the better free plan, Riftone or Moises?
Moises. Its Free plan lets you separate 5 of your own songs per month, up to 5 minutes each, into 2 stems (vocals and instrumental) or 4 stems (vocals, drums, bass, other). Riftone is free to download and you can try separation on built-in demo tracks, but separating your own songs needs Riftone Premium.

What is the maximum song length?
Riftone accepts songs up to 15 minutes. Moises allows 5 minutes per file on Free and 20 minutes on Premium and Pro.
