ORememberMe is a lightweight open source portable task and event reminder created by opessoa. Designed to run without installation, this simple reminder utility is ideal for scheduling one time events or daily recurring tasks directly from a USB flash drive or removable storage device.
When a scheduled date and time arrives, it displays a clear on screen popup notification to alert the user of the upcoming task or event. It can be used for tracking birthdays, meetings, appointments, daily reminders, and important deadlines without relying on cloud services or online accounts.
