## PowerGlass 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
• Learning speed presets - choose Steady, Balanced or Responsive to control how quickly new days are averaged in
• 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
• Fully customisable layouts - full-screen editors let you choose exactly which metrics appear on each page and in the rectangular complication
• 24-hour usage graph showing your drain pattern across the day
• Average battery life at 100% - see what a full charge is really worth on your watch
• Achievements that reward consistent usage and learning milestones
• Power-user tools: inspect data and track learning progress and coverage

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.

## PowerGlass Reviews in United States

### ***** "Very useful"
More informational than the standard battery indicator on the Apple Watch. It has a nice complication that offers more information when opened.
