Wakerupper is an experimental web service that allows users to receive scheduled voice reminders and alerts on their landline telephone or mobile phone, for free. Subscribers no longer need to pay exorbitant call charges to their telephone company for recurring wakeup calls.

To use this service, visit wakerupper.com. Then enter the phone number you would like to be called on, your timezone, the time you want to receive the call, your email address, and an optional 140-character reminder message. You will receive a phone call from Wakerupper at the time you have specified, free of charge. You can also choose to schedule a voice reminder or message for someone else by entering their phone number.

If you apply for their private beta, you will get addition features such as:

+ Voice reminders new
+ Snooze
+ Recurring calls new
+ Unlimited reminders

The website can be accessed from any mobile phone browser to schedule wakeup calls while on the move. Wakerupper is compatible with any phone in United States or Canada.
