Description

Have you ever wondered how long your Apple Watch battery will last?

PowerGlass turns your battery percentage into a live time-remaining prediction, based on how you actually use your watch. By learning your real-world usage patterns, it shows you exactly how many hours you have left.

Your battery drain isn't constant, and neither is your lifestyle. PowerGlass continuously adapts as your habits change, keeping its predictions accurate as your routine evolves.

Key Features

Personalised time-remaining predictions driven by your hourly usage patterns

Dual-mode learning with separate models for Standard and Low Power Mode

Multiple complications: circular gauge, rectangular with usage graph, corner, inline and compact

Depletion time estimate - see the day and time you'll need to charge

Achievements that reward consistent usage and learning milestones

Customisable rectangular complication - choose which metrics to display

24-hour usage graph showing your drain pattern across the day

Power-user tools: inspect data, track learning progress, and adjust learning speed

The more you use it, the smarter it gets - giving you confidence in every charge.

Note: In Low Power Mode, Apple Watch restricts background app refresh. To maintain learning accuracy, open the app periodically while in this mode.
