Just stepped into the smartphone world. Actually we (me and hubby) kind of tip toed in. We've been using the old flip phones for the past ten years or so. Finally found a plan that won't eat every nickel and dime we have so decided to take the plunge. Its been a time consuming few days attempting to learn all the new features on the phones. The one thing we miss is not having a missed call or message alert that is continuous until turned off. Any suggested apps? Ones that are free but secure for the most part is what I'm looking for. Any help is appreciated.
