Yep, PhoneGuard will become the new default for this type of app. They are first to market, and with Bieber and all the people downloading it, good luck to anyone else trying to enter the market after. First to market wins usually, and it will be tough for any competitor to gain any significant market share now. PhoneGuard is now known as THE anti-texting + driving app. By offering the meaty portion for free, there is no competition price-wise anymore.
It will become another brand name that is used by default.
"Hand me a Kleenex"
"Can you Krazy Glue it?"
"I need a Band-Aid"
"Just use some Windex to clean it"
"Just buy her a PhoneGuard if you're worried"
