# StarTeller vs Orbiting Sky

The clearest difference is ads: StarTeller at none against Orbiting Sky's shown. StarTeller also leads on monetization model (free vs free with in-app purchases) and ratings volume (9 vs 1). Orbiting Sky's advantage is update cadence (every 5 days vs every 2 weeks). On price, rating, in-app purchases and device support there is nothing between them.

Both are free to download. StarTeller sells 1 one-off in-app purchase and Orbiting Sky sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for StarTeller against 5.0 for Orbiting Sky. That said, the two scores are not equally well evidenced: StarTeller has 9 ratings behind it against 1, so its average is the more settled of the two.

StarTeller ships an update every 2 weeks, Orbiting Sky every 5 days. The most recent releases landed on November 5, 2026 and October 31, 2026 respectively.
