About this app

Battery Cycle Notes is a private offline journal for manually tracking rechargeable devices. Create device profiles, record charging percentages, start and end times, power source, and notes. The app calculates duration and percentage gain, shows per-device cycle counts and average charging time, offers searchable history with source filters, and exports device history as plain text through Android's share sheet. All information stays on the device. There is no account, server, cloud sync, advertising, analytics, tracking SDK, internet permission, or access to hidden system battery APIs. Light, dark, and system themes, optional sample data, individual record deletion, and full local-data deletion are included.
