Have you ever wondered how long your battery will really last? PowerGlass turns your battery percentage into a live time-remaining prediction, based on how you actually use your devices. By learning your real-world usage patterns — on Apple Watch, iPhone and iPad — 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. On your Apple Watch • A live countdown in hours, learned from your own usage • An energy bar showing the hours left against what a full charge is worth • The day and time you'll need to charge, and your average drain • Your day hour by hour, so you can see which hours cost you the most • Battery history, and a forecast of where it's heading • A five-week trend of your daily average • See exactly how it learned: the calculation behind every learning event • Keeps learning while you're not looking — you don't need to open it • Complications for any face: gauge, simple gauge, corner, inline, and two rectangular styles • Customisable data fields for the rectangular complications • Build your own main page — pick the layout, then choose the metric in every slot • Five colour palettes for the graphs • Low Power Mode is learned separately, so the estimate stays right when you switch • 23 awards for steady habits and learning milestones • Choose how fast it adapts to changes in your routine On your iPhone and iPad • A live countdown in hours, learned from your own usage • An energy bar showing the hours left against what a full charge is worth • The day and time you'll need to charge, and your average drain • Your day hour by hour, so you can see which hours cost you the most • Battery history, and a forecast of where it's heading • A record of every charge and how much it added • See exactly how it learned: the calculation behind every learning event • Keeps learning while you're not looking — you don't need to open it • Widgets for the Home Screen and the Lock Screen • Built for the iPad's screen, in any orientation • Choose how fast it adapts to changes in your routine The more you use it, the sharper it gets.

Verdict

The call

The clearest difference is rating: PowerGlass at 5.0 against TimeGlance's 3.7. TimeGlance's advantage is update cadence (every 4 days vs every 3 weeks) and ratings volume (106 vs 5). On ads, in-app purchases, monetization model and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

PowerGlass holds the better App Store score, 5.0 against 3.7. That said, the two scores are not equally well evidenced: TimeGlance has 106 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 63% of TimeGlance's written reviews are positive against 50% of PowerGlass's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

TimeGlance ships an update every 4 days, PowerGlass every 3 weeks. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
