# My Invisalign vs 22 Hours

The clearest difference is rating: My Invisalign at 4.8 against 22 Hours's 3.7. My Invisalign also leads on ratings volume (64K vs 3) and chart position (#65 vs unranked). 22 Hours's advantage is monetization model (free vs free with in-app purchases). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

My Invisalign holds the better App Store score, 4.8 against 3.7. That said, the two scores are not equally well evidenced: My Invisalign has 64K ratings behind it against 3, so its average is the more settled of the two.

Both ship on a similar rhythm, roughly monthly. The most recent releases landed on October 21, 2026 and October 12, 2026 respectively.
