# Interval Timer vs ExTimer

The clearest difference is update cadence: ExTimer at every 11 days against Interval Timer's every 2 months. ExTimer also leads on review sentiment (100% vs 84%). Interval Timer's advantage is ratings volume (246 vs 4) and iOS requirement (13.0 vs 15.2). On price, rating, ads and in-app purchases there is nothing between them.
