# MultiTone Generator vs Hemi

MultiTone Generator and Hemi both sit at 4.6 stars, but that hides the real split: 80% of MultiTone Generator's written reviews are positive against 32% of Hemi's. MultiTone Generator also leads on monetization model (free with in-app purchases vs subscription). Hemi's advantage is update cadence (every 2 weeks vs monthly) and ratings volume (2.5K vs 355). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. MultiTone Generator sells 7 in-app purchases, starting at $1.49 per month and Hemi sells 2 in-app purchases, starting at $14.99 per month. Whichever you choose, the download price is not the number that matters.

MultiTone Generator holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Hemi has 2.5K ratings behind it against 355, so its average is the more settled of the two. Written reviews point the same way: 80% of MultiTone Generator's written reviews are positive against 32% of Hemi's.

MultiTone Generator ships an update monthly, Hemi every 2 weeks. The most recent releases landed on October 7, 2026 and October 9, 2026 respectively.
