ReceptionRating · Positive reviews · Number of ratings

Carte Vitale holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: Carte Vitale has 122 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 48% of OdySight's written reviews are positive against 41% of Carte Vitale's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

OdySight ships an update every 3 months, Carte Vitale every 2 months. The most recent releases landed on August 21, 2026 and September 21, 2026 respectively.
