"Continued use of GPS running in the background can dramatically decrease battery life."
Every time an ambulance, fire engine or police car driving for an emergency and in order to provide help for people in need, they risk other's lives by potential accidents due to their speed. Most of these accidents happen when the cyclists, motorists, pedestrians, or joggers, are listening to loud music on their earphone/headphones at the time that the alarm vehicles are passing by.
Having BlueAlert app on your iPhone what makes you feel safe when you are on your bike, by mute the volume of the music and starting to warn you about possible dangerous situations, including Police cars, ambulances and firefighters behind your bike.
Remember, BlueAlert is intended to be used for Cyclists, when biking outdoors in the streets, in highways and public places, while using their earphones. In this case, the earphone's microphone is being used by BlueAlert sound detection technology to detect any possible alarms and other dangerous situations for them. BlueAlert is not intended for using indoors or inside the cars.
BlueAlert is using very low energy in your phone. In case you forgot to stop the app, it is not a big deal! However, using the app for about 1 to 2 hours a day does not use any battery in your phone!
BlueAlert is an offline app that does not use your Internet data. It only uses your Headphone or Earphone's microphone to detect the dangerous situations and Alarms in your area.
