QuickReminder is a lightweight reminder application designed specifically for HarmonyOS-based wearable devices. The app allows users to create short-term reminders (in seconds) and receive a notification when the time expires.
This app was built to serve simple, fast scenarios such as reminding users of tasks while their hands are busy (e.g., while eating, cooking, or working). With just a few taps, users can set a quick alert directly from their wrist.
