chdv - The battery app

chdv makes it easy to keep track of devices while they charge and estimate when they can be unplugged again. The app is easy to use and requires no knowledge of batteries or chargers.

Getting started is easy: Add a "Setup" for a new device and check its battery level once while it is charging. chdv uses this data to predict future charging times. Experienced users can also enter the battery capacity and charger power to avoid interruptions and follow-up questions.

chdv creates reminders for charging sessions and, if you like, even HomeKit automations that switch your smart plugs on and off automatically. This lets you use cheaper off-peak electricity overnight or power from your solar panels during the day.

Whatever you want to charge—a phone, power bank, tools, bike computer, toothbrush, or another device—chdv reminds you reliably and can automate your smart plugs too.
