Teia is an application that represents the solar system using 3D models. But, unlike the rest of the applications published in the stores, the objective of this application is to show the objects that this system is composed of by teaching perceptible and localizable curiosities on the surface of the planets. What are the rilles on the Moon? And the rupes on Mercury? Does Jupiter have a pearl necklace? Is really there a face on Mars? Why does Neptune have such an intense blue color? Learn every corner of the Solar System with this great collection of features spanning a total of over 40 pages, structured and developed by experts in the Planetary Astronomy field. The models represented have been designed taking care of the maximum possible realism, from the true color of the surface of Venus, to the structure of the ring systems. In this way, you have the feeling of visiting each planet only a few thousand kilometers away. The models represented are the following: * Mercury. * Venus. * Land. * Moon. * Mars. * Jupiter. * Saturn. * Uranus. * Neptune. Application developed by Himalaya Computing and Órbita Bianca.

Verdict
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.
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. 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.
