# Star Chart AR vs Teia

The clearest difference is update cadence: Star Chart AR at every 5 weeks against Teia's every 10 months. Star Chart AR also leads on review sentiment (25% vs 0%) and iOS requirement (11.0 vs 13.0). Teia's advantage is rating (3.7 vs 3.3). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Star Chart AR sells 2 one-off in-app purchases and Teia sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Teia holds the better App Store score, 3.7 against 3.3. Both are backed by a comparable volume of ratings — 15 and 7 respectively. Written reviews complicate that: 25% of Star Chart AR's written reviews are positive against 0% of Teia's, so the app with the better star average is not the one people write more warmly about.

Star Chart AR ships an update every 5 weeks, Teia every 10 months. The most recent releases landed on October 24, 2026 and October 27, 2026 respectively.
