Danger!!! Dont actually use this!!! Bad for your phone!

This app is neat as a novelty but actually using it will cause about the highest battery drain of any app possible.
The funny thing is who this is targeted at are the same people who are going to want to do everything possible to make sure their devices dont run out of battery. A cellphone when out hiking could save your life... that is unless you used this app for the short period it can run.

Also people need to be aware that using an app like this often will greatly decrease the overall life expectancy of their iPhone. Just using the battery quickly so that you must recharge is bad enough and takes from the batter life.

BUT running the battery at high temperature (that this app does cause) will cause quick and irreparable damage to your phones battery. Read about how these batteries work and you will see that using the battery quickly causes excess heat and hot batteries dont last as long as cool batteries so its a double fold assault on your battery.
