# Sun n Moon vs PocketGrib

Sun n Moon and PocketGrib both sit at 5.0 stars, but that hides the real split: 93% of PocketGrib's written reviews are positive against 59% of Sun n Moon's. PocketGrib also leads on ratings volume (577 vs 8). Sun n Moon's advantage is price ($0.99 vs $5.99) and iOS requirement (8.2 vs 15.0). On rating, update cadence, ads and in-app purchases there is nothing between them.

Sun n Moon costs $0.99 and PocketGrib $5.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Sun n Moon holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: PocketGrib has 577 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 59% of Sun n Moon's written reviews are positive against 93% of PocketGrib's, so the app with the better star average is not the one people write more warmly about.

Sun n Moon ships an update every 5 weeks, PocketGrib every 2 months. Both last shipped on November 6, 2026.
