Moises: The Musician's App

What it does

Moises is an AI-powered application designed for musicians. Its primary function is to take any song and separate it into individual instrument and vocal tracks. This allows users to create backing tracks for practice, isolate specific parts to learn, change a song's key and tempo, and view automatically generated chords. It serves as a comprehensive toolkit for practice, learning, and remixing.

Where it shines

The app's core strength is its interactive AI mixer. After uploading a song, the user is presented with a clean interface showing individual tracks for vocals, drums, bass, and more (01:10). The ability to instantly mute a vocal track to create a karaoke version or solo a bassline to study it is powerful yet simple. Another standout is the integrated chord and lyrics view (03:22), which highlights chords in real-time as the song plays, transforming the app into a powerful learning tool.

UX highlights

Direct Manipulation: The track mixer (01:18) allows for intuitive control. Users can directly tap icons to mute/solo or use sliders for volume, providing immediate audio feedback.
Contextual Tooltips: The app uses subtle tooltips to guide new users, like the 'Tap & hold to solo' message (01:11), without being intrusive.
Clear Premium Feature Gating: Premium features are clearly marked with a lock icon. Tapping one, like 'Bass' separation at 02:01, triggers a relevant upgrade prompt, explaining the value at the point of need.
Beta Feature Labeling: The 'Chord Grid with Lyrics' feature is marked with a 'BETA' tag (03:23), managing user expectations about its performance and encouraging feedback.
Smart Metronome: The app can intelligently add a click track to any song, and the settings for it are comprehensive, including volume, subdivision, and tempo control (02:43).
Organized Settings: Song-specific settings are neatly organized in a bottom sheet (03:32), keeping the main player interface clean and focused on playback and mixing.

Monetization & growth

Moises employs a freemium model with contextual paywalls. Instead of a single, mandatory paywall, the app places upgrade prompts on advanced features. For example, trying to separate more than the basic tracks (01:57) or enabling HI-FI audio quality (02:20) presents a paywall. This approach allows users to experience the core value for free while encouraging conversion for deeper functionality. The app offers both yearly and monthly plans, with the yearly option heavily discounted to incentivize a longer commitment (02:04).

Who it’s for

The app is clearly built for a wide range of musicians. Students can use it to isolate and learn difficult parts of a song. Vocalists and instrumentalists can create custom backing tracks for practice or performance. Music teachers could use it as a teaching aid, and even producers might use it for quick sampling or remix ideas. Its utility spans from beginners learning their first chords to professionals needing a flexible practice tool.

Notes & opportunities

The initial onboarding requires a sign-up before the user can interact with any song, which adds friction (00:35). Allowing users to play with a demo song first could demonstrate the app's 'magic' more effectively and potentially increase sign-up conversion. The file upload process also has several steps (01:45-01:57), which could possibly be streamlined. Finally, while the contextual paywalls are smart, a central screen comparing all Free, Premium, and Pro features could clarify the full value of upgrading.
