# 7 Planets vs 321!

The clearest difference is update cadence: 321! at every 2 weeks against 7 Planets's every 4 months. 321! also leads on review sentiment (66% vs 39%) and iOS requirement (9.0 vs 15.0). 7 Planets's advantage is monetization model (free vs free with in-app purchases) and rating (4.5 vs 4.2). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. 7 Planets sells 2 in-app purchases, starting at $1.99 per month and 321! sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

7 Planets holds the better App Store score, 4.5 against 4.2. Both are backed by a comparable volume of ratings — 80 and 32 respectively. Written reviews complicate that: 39% of 7 Planets's written reviews are positive against 66% of 321!'s, so the app with the better star average is not the one people write more warmly about.

7 Planets ships an update every 4 months, 321! every 2 weeks. The most recent releases landed on October 21, 2026 and October 20, 2026 respectively.
