# ROCKET vs How do Things Fly?

The clearest difference is rating: How do Things Fly? at 5.0 against ROCKET's 3.7. ROCKET's advantage is review sentiment (100% vs 80%) and ratings volume (3 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. ROCKET sells 1 one-off in-app purchase and How do Things Fly? sells 4 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.

How do Things Fly? holds the better App Store score, 5.0 against 3.7. Both are backed by a comparable volume of ratings — 3 and 1 respectively. Written reviews complicate that: 100% of ROCKET's written reviews are positive against 80% of How do Things Fly?'s, so the app with the better star average is not the one people write more warmly about.

ROCKET ships an update every 5 months, How do Things Fly? every 4 months. Both last shipped on October 6, 2026.
