# CuriosityStream vs Space Channel

The clearest difference is monetization model: Space Channel at free against CuriosityStream's subscription. Space Channel also leads on review sentiment (57% vs 31%) and iOS requirement (10.2 vs 15.1). CuriosityStream's advantage is update cadence (monthly vs every 22 months) and ratings volume (6.3K vs 579). On price, rating, in-app purchases and device support there is nothing between them.

Both are free to download. CuriosityStream sells 6 in-app purchases, starting at $5.99 per month and Space Channel sells 6 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.6 for CuriosityStream against 4.7 for Space Channel. That said, the two scores are not equally well evidenced: CuriosityStream has 6.3K ratings behind it against 579, so its average is the more settled of the two. Written reviews are what separate them: 31% of CuriosityStream's written reviews are positive against 57% of Space Channel's.

CuriosityStream ships an update monthly, Space Channel every 22 months. The most recent releases landed on October 14, 2026 and October 13, 2026 respectively.
