Blitara Burst Timer overview

Blitara Burst Timer is a straightforward HIIT interval timer built for people who want to focus on training, not configuration. Set your number of rounds, choose work duration and rest duration, and start. The app handles the countdown and alerts you with vibration between phases so you never lose track of where you are in your session. The timer screen shows a large visual countdown along with the current phase — work or rest — and which round you are on. Themes let you switch between light and dark appearances depending on your environment or preference. Four named themes are available, two light and two dark, each selectable from a color dot picker in settings. All workout configurations are stored locally on your device. No account, no sync, no internet required. The app runs entirely offline and always will. A short two-screen onboarding walks new users through the core concepts on first launch. After that, the timer is front and center. If you want to review the introduction later, a settings option resets the onboarding flag so it plays again on next launch. Settings also include date format selection and a default start tab option so the app opens exactly where you want it each time.
