Name: Runtime - Battery Forecast & Alerts
Author: VegetablesInc

Runtime turns raw battery-percentage readings into a straight answer: how many hours or days of use are left, and when you'll need to charge next.

FORECAST YOU CAN TRUST
Runtime watches your battery drain in the background and builds a rolling estimate of remaining runtime. Forecasts are graded by confidence: right after a fresh install (or a reset), it tells you it's still collecting data instead of guessing; once it has enough history, it shows hours or days remaining and the approximate time you'll hit empty.

12-HOUR DETAIL VIEW
A swipeable chart shows the last 12 hours of battery level, color-coded by what you were doing at the time - idle, sleep, a workout, or on the charger - so a sudden drop is easy to explain. Pan back up to ten days to review earlier windows.

7-DAY TREND
A second view rolls the same data up into a week-at-a-glance trend, with your average daily drain.

CHARGE CYCLE LOG
A simple history of your recent charge cycles.

GLANCE WIDGET
Check your forecast without opening the app, right from the watch's glance view.

ALERTS THAT RESPECT YOUR TIME
Two configurable low-battery thresholds, a runtime-remaining warning (under 24h / 48h), a nudge if you left the watch on the charger at 100%, and a note when it reaches your charge target - plus quiet hours and a snooze option, so you're not pestered overnight or mid-meeting.

PRIVATE BY DESIGN
Runtime has no network permission and never sends data anywhere. Everything it tracks stays on your watch.

Available in English, Russian, Czech, German, French, Italian, Polish, and Spanish.

Supports a wide range of Garmin watches, including the fenix 7 series, epix 2 series, Forerunner 255/265/955/965, Venu 2 series, Venu 4, and vivoactive 5.
