# CHRONGRAPH vs Swarm II

The clearest difference is rating: Swarm II at 4.7 against CHRONGRAPH's 2.3. Swarm II also leads on ratings volume (15K vs 3). CHRONGRAPH's advantage is review sentiment (50% vs 41%) and iOS requirement (8.0 vs 15.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Swarm II holds the better App Store score, 4.7 against 2.3. That said, the two scores are not equally well evidenced: Swarm II has 15K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 50% of CHRONGRAPH's written reviews are positive against 41% of Swarm II's, so the app with the better star average is not the one people write more warmly about.

CHRONGRAPH ships an update every 2 months, Swarm II every 6 weeks. The most recent releases landed on October 24, 2026 and October 28, 2026 respectively.
