Description

Intermittent Fasting Timer keeps your fasting and eating windows on your wrist, driven by your own weekly schedule. No starting or stopping a timer by hand. HOW IT WORKS Set your eating window by clock time for each day of the week, Sunday through Saturday. From then on the watch reads the time of day against today's window and always shows where you are, fasting or eating, with a live countdown to the next change. • Fasting view: a progress ring fills toward your eating window, with elapsed fasting time, percent complete, and time left until you eat. • Eating view: a clear countdown to your window's close. • Glance: check your status from the glance carousel without opening the app. STAY ON TRACK Optional notifications (on supported watches) tell you when a window opens or closes, plus a two-hour heads-up before each. A nudge to keep fasting, or a reminder that your eating window is almost over. Turn them on or off any time. FLEXIBLE • Edit any day's window in seconds with the built-in time picker. • End the current cycle early, or stop for the day and resume automatically tomorrow. • Works across compatible Garmin watches. Touch & button, round & rectangular, color & high-contrast. BUILT RESPONSIBLY No streaks, no "longest fast" records, no pressure to push longer. A calm, honest timer for your routine. UNLOCKING Unlock the full app once with a code from aeviriumstudios.com — yours to keep, no subscription. Please consult a clinician before fasting if you are pregnant, diabetic, take medication, or have a history of disordered eating. This app is a timer, not medical advice.

What is new

Fixed Notifications now show their full message — alerts were firing with blank text on some watches. Smoother schedule scrolling on touch watches: swipe through your days one at a time, no dead swipes, no jumping back to the top. Improved End Cycle keeps your schedule — break a fast early and your eating window still closes at its scheduled end time. Cleaner menu: single-line options with text that fits every screen, and a redundant header removed.
