# CuriosityStream vs StreamTwin

The clearest difference is review sentiment: StreamTwin at 100% against CuriosityStream's 31%. StreamTwin also leads on monetization model (freemium vs subscription) and update cadence (every 4 days vs monthly). CuriosityStream's advantage is ratings volume (6.3K vs 1) and device support (4 vs 1). On price, ads, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. CuriosityStream sells 6 in-app purchases, starting at $5.99 per month and StreamTwin sells 2 in-app purchases, starting at $14.99 per month. Whichever you choose, the download price is not the number that matters.

StreamTwin holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: CuriosityStream has 6.3K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 31% of CuriosityStream's written reviews are positive against 100% of StreamTwin's.

CuriosityStream ships an update monthly, StreamTwin every 4 days. The most recent releases landed on October 20, 2026 and October 8, 2026 respectively.
