Verdict

The call

ReceptionRating · Positive reviews · Number of ratings

global storms holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: global storms has 13K ratings behind it against 26, so its average is the more settled of the two. Written reviews complicate that: 42% of global storms's written reviews are positive against 68% of Cyclono's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

global storms ships an update every 3 weeks, Cyclono every 2 months. The most recent releases landed on October 16, 2026 and October 13, 2026 respectively.
