Beecon is a home automation app for your iPhone.
As an interface to things, Beecon allows you to create regions using iBeacons or GPS and define actions that are called when you enter or leave them. You can also use shortcuts in your Today View and in the app itself to manually control HomeKit accessories, LIFX, Philips Hue and Lux lights, IFTTT recipes, web services or common infrared appliances, including conventional air conditioners or vacuum robots (requires iTach infrared module).
Beecon also offers audible feedback for the visually impaired and spoken reminders that allow you to listen to your calendar events or simple notes when you enter or leave your regions.

Important: Continued use of GPS running in the background can dramatically decrease battery life.
