# Flex Mobile App vs Invisalign Practice App

The clearest difference is rating: Invisalign Practice App at 4.9 against Flex Mobile App's 4.0. Invisalign Practice App also leads on ratings volume (4.7K vs 13). Flex Mobile App's advantage is review sentiment (75% vs 45%) and monetization model (free vs ad-supported). 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.

Invisalign Practice App holds the better App Store score, 4.9 against 4.0. That said, the two scores are not equally well evidenced: Invisalign Practice App has 4.7K ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 75% of Flex Mobile App's written reviews are positive against 45% of Invisalign Practice App's, so the app with the better star average is not the one people write more warmly about.

Flex Mobile App ships an update monthly, Invisalign Practice App every 3 weeks. The most recent releases landed on September 6, 2026 and September 26, 2026 respectively.
