Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
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.
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.
