the app is good but it might be not working sometimes – Sticker Maker Stickers Creator Review

For those who downloaded the app and are having the issue that an ad pops up, you close it and then screen goes completely blank, try quitting the app and turning off the Wi-Fi, then start it again, it should work, anyway sometimes when Wi-Fi is on it could happen again and over and over again just because of the ad bug, needs some kind of update.
