1 word. useless. there is absolutely no use for this thing. 1st it said I CAN'T SHARE because a daily LIMIT is reached. even tho I DIDN'T even share any thing yet because I JUST DOWNLAODED IT. 2nd it's so bad if you are in a hurry the ads block it and the premium stuff.. overall useless I would not recommend. thank God I'm not in hurry Im downloading the orther one rn. It would have been good if the SHARING NOT LIMITED TO A FRICKING 5/DAY.

Really good app for file scanning and shareing ....really helpful saves time by auto crop ..just some ads are there but it's just normal in most of the free app and with good features it can be neglected...if you have to send files with many pages and you doesn't want to crop each and every really appreciated yo install
