Lembra is a native, fully offline app to manage cards for recurring alerts and reminders: car and motorbike paperwork, home tasks, pet vaccinations, kids' appointments, documents, licenses and more. Features: * Cards with title, category, start date, optional time and location, repeat interval, number of repetitions and how many days in advance to warn you. * A local notification is fired automatically the chosen number of days before EACH occurrence, not only the last one. * Editable and deletable cards; alerts are cancelled and rescheduled on change. * Categories with filtering: Car, Motorbike, Home, Pets, Kids, Documents, Licenses and Misc. * Light/dark/system theme and configurable primary and accent colors. * Alarms survive a device reboot. * Optionally dump every occurrence as events into your device calendar. No account, no backend and no internet access: everything is stored locally with Room.
