The HAZ Umbrella app communicates with your umbrella when it is within range; when it is out of range, your phone will remind you where it was last connected.
It also conveniently notifies you of the latest weather information if you forget or are too busy to check the weather forecast before you go out, reminding you to carry the HAZ Umbrella whenever needed. Youll never get caught by an afternoon shower, or exposed to high UV rays.
Note:
"Continued use of GPS running in the background can dramatically decrease battery life."
