Forzify

Forzify is a no-frills interval timer built specifically for HIIT training. Whether you are doing Tabata, circuit rounds, or a custom interval protocol, the app gives you precise control over every phase of your session. Set the number of rounds, the duration of each work phase, and how long your rest periods last. Vibration alerts signal transitions between phases so you stay focused on the workout instead of watching the screen. Everything runs locally on your device. No account, no sync, no subscriptions. Your saved timers and session preferences live entirely on-device and are available instantly when you open the app. The interface adapts to how you like to browse your saved configurations. Choose between compact rows, cards, or a grid layout, set your preferred sort order, and pick which tab opens by default when you launch the app. A persistent bottom tab bar keeps every section within one tap. Forzify is straightforward by design. Open it, pick a timer, press start.
