GPSNotifier 1.0 for iPhone 4 – Receive Location-Based Alarms/Messages

jeTap, Inc., today is pleased to introduce GPSNotifier 1.0 for iPhone 4, their app that sounds an alarm and displays a text message when the user arrives at a chosen location. Relying on Apple’s new Region Monitoring, an always-on cell tower positioning system, the app and alarm are automatically activated when the device enters any specified alarm zone. Its features include: 64 user-definable alarm locations; proximity sensitivity control; and location entry using the address book, map, or current location. Because it does not make use of standard, satellite-based GPS data, the app does not make any additional power demands on the battery.
GPSNotifier 1.0 is an alarm based not on time, but place. Now, a user can take a to-do like “Call Bob the next time I’m in Tucson,” or “Check on lease terms the next time I take the car into the dealer for service,” and set an alarm and message on their iPhone 4 that will patiently wait, without running an app or consuming any power, until the user reaches the alarm location. This type of location-based notification has been impractical until recently, because, as Apple advises, “Continued use of GPS running in the background can dramatically decrease battery life.”
With iPhone 4 Apple introduced a new, supplementary positioning system based on a complex algorithm performing continuous positional triangulations between cell phone towers. In metropolitan areas with many such towers, measurements can be highly accurate. And because the iPhone is constantly in “Receive” mode, searching for cell towers, these location coordinates are purchased with practically no cost to the battery. This continuous, background, global positioning system is called Region Monitoring by Apple, and it is the technology that makes GPSNotifer possible.
