# Kilo vs FastTime

The clearest difference is ads: Kilo at none against FastTime's shown. Kilo also leads on update cadence (fortnightly vs monthly). FastTime's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 26.1). On price 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.

Kilo ships an update fortnightly, FastTime monthly. Both last shipped on October 31, 2026.
