Great app for quick reminders. Small in size, no syncing with anything - works only in local mode. Number of clicks required to schedule a reminder is minimal (3 at its best!). Very customizable - features many settings (for such a simplistic app) to tune it to your needs for maximum efficiency. NB! The alarm/postpone spinners are not designed for manual input so I suggest to refrain from inputting the values manually.
