An easy-to-use timer app that eliminates the hassle of starting a timer to the absolute minimum. 【Key Features】 One-Tap Start: Just press once and the countdown for the time on the preset button starts immediately! Buttons can be freely deleted or their times edited, and the size can be adjusted to your liking with a slider. Auto Start: Turn this ON, and the countdown with your "previously set time" will start the moment you open the app next time! The ultimate hassle-free feature! Swipe & Numpad Input: For times not available on the buttons, simply tap the time display to enter them directly. Choose your preferred method: swipe or numpad! Furthermore, the entered time is automatically added as a "Recently set time" one-tap button, saving you the trouble of repeatedly entering your frequently used times! Alarm Feature: The zero-count notification visually alerts you by turning the screen red. A reliable design that automatically switches between sound and vibration depending on your device's silent mode settings.

The clearest difference is update cadence: 1 at every 2 weeks against HIIT Timer's every 5 weeks. 1 also leads on iOS requirement (17.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.
