The clearest difference is price: Teia at Free against Exoplanets's $1.99. Teia also leads on rating (3.7 vs 2.0) and iOS requirement (13.0 vs 17.6). Exoplanets's advantage is in-app purchases (none vs 1) and review sentiment (17% vs 0%). On ratings volume, update cadence, ads and device support there is nothing between them.

Teia is free to download; Exoplanets costs $1.99 up front. Teia sells 1 one-off in-app purchase. Exoplanets asks for nothing beyond the download.

Teia holds the better App Store score, 3.7 against 2.0. Both are backed by a comparable volume of ratings — 13 and 7 respectively. Written reviews complicate that: 17% of Exoplanets'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.
