How long has your electric shaver actually been sitting on empty? When did you last charge your earbuds? For devices without their own battery indicator, it's genuinely hard to know. C% - Charging Tracker keeps tabs on all of them. Tap once to log a charge, and the app estimates how much battery life is left based on your real habits, not just spec-sheet numbers. • Smart and personalised After a few charges, C% learns your actual usage pattern for each device. Your laptop that never makes it the full 20 hours? Your earbuds you charge twice a day? The estimates adjust to match. The more you use it, the more accurate it gets. • Everything at a glance The main screen shows all your devices sorted by urgency, so the ones that need attention rise to the top. A summary bar at the top tells you how many are fine, and how many need charging right now. Tap any device to see its full charge history, weekly usage chart, and how your habits compare to expected battery life. • Widgets that actually do something Add the home screen widget to see battery status for your most important devices without opening the app. Tap the bolt button right from the widget to log a charge instantly. • Notifications that know when to stop C% sends a heads-up before each device's battery is predicted to run out, and a nudge if you've gone unusually long without charging. No constant buzzing, just timely reminders when they matter. • Built for real life Supports smartphones, tablets, smartwatches, wireless earbuds, laptops, game controllers, e-readers, electric shavers, smart toothbrushes, drawing tablets, portable speakers, and more.
