Harmonizr is a vocal harmonizer offering a unique and fun user interface. Plug in a pair of headphones and sing a melody, tapping the correct key center buttons, and Harmonizr will follow, synthesizing up to three voices of automatic harmony in your own voice. Plug in a MIDI keyboard, or use the on-screen one, and you can sing harmony like Imogen Heap or Jacob Collier, matching every note you play. Harmonizr also can also be used as an Audio Unit (AUV3) extension within other apps, such as GarageBand, AUM, or Cubasis, and can be controlled by MIDI controller apps like SoundPrism.

Verdict
The clearest difference is price: Harmonizr at $4.99 against DM10's $17.99. DM10's advantage is rating (4.6 vs 4.2) and update cadence (every 4 weeks vs every 4 months). On review sentiment, ratings volume, ads and in-app purchases there is nothing between them.

DM10 costs $17.99 and Harmonizr $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.
DM10 holds the better App Store score, 4.6 against 4.2. Both are backed by a comparable volume of ratings — 54 and 27 respectively. Written reviews complicate that: 72% of DM10's written reviews are positive against 74% of Harmonizr's, so the app with the better star average is not the one people write more warmly about.
DM10 ships an update every 4 weeks, Harmonizr every 4 months. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
