# Planetary Weather vs Encyclopedia

The clearest difference is update cadence: Encyclopedia at monthly against Planetary Weather's every 7 months. Planetary Weather's advantage is review sentiment (100% vs 83%) and rating (4.0 vs 3.8). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Planetary Weather sells 2 one-off in-app purchases and Encyclopedia sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Planetary Weather holds the better App Store score, 4.0 against 3.8. Both are backed by a comparable volume of ratings — 11 and 14 respectively. Written reviews point the same way: 100% of Planetary Weather's written reviews are positive against 83% of Encyclopedia's.
