Verdict
The clearest difference is rating: Kactoily at 2.5 against Mobius's 2.0. Kactoily also leads on update cadence (every 2 weeks vs every 2 months) and iOS requirement (13 vs 15.6). Mobius's advantage is ratings volume (332 vs 11). On price, review sentiment, 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.
Kactoily holds the better App Store score, 2.5 against 2.0. That said, the two scores are not equally well evidenced: Mobius has 332 ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 26% of Mobius's written reviews are positive against 25% of Kactoily's, so the app with the better star average is not the one people write more warmly about.
Mobius ships an update every 2 months, Kactoily every 2 weeks. The most recent releases landed on November 11, 2026 and November 5, 2026 respectively.
