That's the time Apple uses for their iPhone promotions. Once you find out about it, you'll start seeing it a lot. Might as well get rewarded for it.

Verdict

The call

The clearest difference is review sentiment: Nine41 at 100% against CuriosityStream's 31%. Nine41 also leads on monetization model (free with in-app purchases vs subscription) and rating (5.0 vs 4.6). CuriosityStream's advantage is ratings volume (6.3K vs 3) and device support (4 vs 2). On price, ads and in-app purchases there is nothing between them.

Nine41 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 3, 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 Nine41's.
