# Pocket vs Knowledge Observatory

Pocket and Knowledge Observatory both sit at 4.9 stars, but that hides the real split: 100% of Knowledge Observatory's written reviews are positive against 67% of Pocket's. Knowledge Observatory also leads on device support (3 vs 1) and iOS requirement (15.0 vs 17.0). Pocket's advantage is ratings volume (7.4K vs 1) and chart position (#25 vs unranked). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Pocket sells 17 in-app purchases, starting at $19.99 per month and Knowledge Observatory sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for Pocket against 5.0 for Knowledge Observatory. That said, the two scores are not equally well evidenced: Pocket has 7.4K ratings behind it against 1, so its average is the more settled of the two. Written reviews are what separate them: 67% of Pocket's written reviews are positive against 100% of Knowledge Observatory's.

Both ship on a similar rhythm, roughly every 4 days. The most recent releases landed on November 3, 2026 and October 29, 2026 respectively.
