# My Invisalign vs Smile Express

The clearest difference is chart position: My Invisalign at #69 against Smile Express's unranked. Smile Express's advantage is update cadence (fortnightly vs monthly). On price, ads, in-app purchases and device support 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 ships an update monthly, Smile Express fortnightly. The most recent releases landed on October 29, 2026 and October 25, 2026 respectively.
