Concenturio is an easy to use reminder tool that can remind you of tasks, appointments, birthdays or other upcoming events. You can configure simple, one-time reminders or set up recurring events that remind you every day (or only on specific days of the week) or on a weekly, monthly or yearly basis. Once a task is due, the program can bring up a pop-up window and/or sound an alarm. You can choose from the buil-in alarm sounds or use your own MP3 file.
