Amazing
Everyone sees these things on vine and it seems like it has all the modern stuff (like different number fonts for the time on your lock screen, a different slider, etc.) but never trust vine or instagram. All those advertisements are scams. If you want an honest advertisement, look at these reviews. This app is actually amazing. You can customize your lock screen with a background, a time/date background, and a slider background. They have a large selection of those 3 categories of backgrounds too. I dont mean to sound like a telemarketer or someone who advertises regularly, but if you have any questions, DM me on Instagram @sofia_loves_gotham
