VatAlert is an app that lets you receive instant notification of your position as soon as you enter a controlled area, or as soon as you approach one. You can also receive notification of your position when you have completed your flight.

If you have flown before, you know how frustrating it can be to wait for an ATC to open and to receive a notification that you are approaching or leaving a controlled area. With VatAlert, you can enter the ATC you want to be notified about and receive instant notification when the ATC becomes available.

VatAlert works with VATSIM data servers, which means that it will only notify you of the ATCs that are currently available.
