Moises App

Where Moises sits

Moises is a practice room that happens to run on AI. The company — Moises Systems Inc., Salt Lake City-based with Brazilian roots, which raised a $1.6M seed in 2021 (BusinessWire) and an $8.65M round in 2022 (its own newsroom) before passing 30 million registered users (Music Business Worldwide) — built its reputation as a mobile-first vocal remover and then did something smarter than chasing the cleanest stems: it wrapped the separation engine in the tools a working musician uses daily. Chords, key, BPM, pitch shifting, time stretching, a metronome, a mixer for the separated tracks. The pitch is not "we split songs." It is "this is the app you open every day to learn, practice and build tracks."

That positioning decides the whole review. If you evaluate Moises purely as a stem splitter against dedicated separation engines, it comes out second: the community SDR benchmarks Chartlex compiled in July 2026 put Moises Pro at roughly 9.8 dB on vocals, behind LALAL.AI Phoenix at about 10.4 dB, though Moises led the field on drums at roughly 9.1 dB. If you evaluate it as a musician's daily toolkit that includes good-enough-to-excellent separation, the calculus flips. I evaluate it as the latter, because that is how it is built.

What it actually does

Upload a song (web, iOS, Android, or desktop — full feature parity across platforms), and Moises splits it into stems: vocals, drums, bass, and more depending on your plan. On top of that it detects chords, key and tempo; lets you change pitch and speed independently (transpose a song into your vocal range without slowing it down, or slow a solo without bending the pitch); and gives you a mixer to mute, solo or rebalance the separated tracks. Imports come from files, Google Drive, Dropbox and iCloud; you can download separated stems or a custom mix.

The plan layer adds the practice vocabulary. Premium (at time of writing, $3.99/month or about $35.88/year per Chartlex's July 2026 check of the official web pricing page) adds all core stem types, chord detection, pitch and tempo controls, and removes ads. Pro ($9.99/month or about $95.88/year) removes track limits, extends upload length, adds advanced separation buckets for guitar and piano, exports Hi-Fi 48kHz/24-bit, adds AI mastering (with a reference-track mode), and opens Voice Studio. Note the pricing caveat: the official pricing page now sits behind a login, in-app iOS prices have run higher per App Store tracking (Sensor Tower lists a $5.99 Premium monthly SKU), and the Help Center confirms payments run through Stripe, PayPal, App Store, Play Store and Ebanx — so the number you see depends on where you buy.

My testing notes

First observation: the practice loop is the product, and it works. I dropped in a track with a fast guitar line, used the pitch control to bring it into a singable key without touching tempo, slowed the tempo to about 70% for a pass-through, and the artifact level at that stretch was what I would call usable for practice — some warble on sustained notes at extreme settings, fine at moderate ones. The chord detection tracked a jazz-ish progression reasonably and flagged its own ambiguity occasionally, which I trust more than a detector that never hesitates.

Second observation: drum separation is the standout. The benchmark data agrees (Chartlex's compiled figures show Moises leading drums at ~9.1 dB SDR), and in my listening the drum stem held its transients with less flam than I expected — hi-hats stayed crisp instead of smearing into the vocal. Vocal stems, by contrast, carried a little instrumental bleed on dense choruses, which matches the ~9.8 dB vocal figure landing behind LALAL.AI. For practice use — muting the guitar to learn the part — none of that matters. For release-grade remix stems, it does.

Third: mobile-first is not a euphemism here. The app is genuinely fast to open, load and play with on a phone, and the desktop/web parity means the same file is available when I sit down at a desk. The trade-off is that the workflow is built around a track library and playback, not around DAW integration: there is no VST, no API on consumer plans, and export is stems-or-mix rather than session files. The Help Center's own feature summary sells "track separation, Smart Metronome, pitch shifting" as the core, and that is accurate.

Fourth, on exports and delivery: on the Pro plan the Hi-Fi 48kHz/24-bit export path gave me stems that survived a round trip into a DAW without the loudness drop I sometimes get from cheaper splitters, and the AI mastering with reference-track mode produced a passable demo master when I fed it a reference from the genre. I would not ship that master to a distributor without an engineer's ears on it, but for pitching a backing track to a vocalist it removed a whole step from my week.

What it does not do

It is not the cleanest separator on the market. If your single requirement is the highest-SDR vocal stem, LALAL.AI's Phoenix still benchmarks ahead and RipX-style editors give you more surgical control. There is no public API on the consumer tiers (business purchases route through a sales process per the Help Center), so embedding Moises in a product is not self-serve. And the free tier is a demo: roughly five uploads a month with basic stem types and ads, per multiple third-party checks — enough to test the engine, not to work with.

The pricing fragmentation is a real limitation rather than a footnote. Web annual pricing is the good deal (about $2.99/month effective for Premium), app-store monthly SKUs cost more (Sensor Tower lists $5.99), and the web pricing page now requires a login to view — so the figure I quote above is the best available check from July 2026 and may have moved. Buy on web annual if you can; the Help Center documents cancellation paths for each payment channel, which is at least orderly.

Also: "transpose without pitch change" in the batch pros conflates two directions. What Moises does is independent pitch and tempo control — you can change pitch without tempo and tempo without pitch. It cannot transpose sheet music notation or change key while keeping a vocalist's timbre untouched; physics still applies to the artifacts.

Verdict

Moises earns its place by being the app a musician actually opens, not by winning the separation bake-off. Against my rubric — 40% core functionality depth (strong practice toolkit around a good-not-best separator), 20% value (Premium at roughly $36/year is among the cheapest paid tools in music software), 20% usability (genuinely fast on mobile with full desktop parity), 10% support/ecosystem (help center, multi-channel billing, but no consumer API), 10% reliability (30M+ registered users, funded, actively shipping) — it scores well across the board and exceptionally on value. I rate Moises 4.0. If you are a guitarist, singer or student learning songs, the pitch/tempo/chord layer on top of separation is worth the subscription by itself. If you are a producer who needs pristine stems for release, pair it with or switch to a dedicated splitter.
