Can't scan unless I pay + unlimited ads with every touch on the screen. Before, I didn't mind the unlimited annoying ads because I could remove scanning water mark. However, after sometime, they will not let you export the scanned documents unless you pay!! what is the point of all the annoying ads then???

Hi Mohammad, I apologize for the ads. We will optimize the app and reduce ads in the future. This app is completely free, so we need ads to earn revenue and provide you with better products. Thank you very much for your understanding!🌹

I installed the app then I didn't notice theres a subscription first just to use the trial. Then I have uninstall directly the app since I don't know how use it properly. Then after few days I got a notification from my gcash that my balance was deducted because of the subscription when at the first place I didn't get to enjoy the service of the app. Then I keep on sendingrequest refund email for a few days on their support email and I've got NO response. So I decided to make a review here.

I find this scanner very easy to use. The feature of batch scanning is so good that it allows you to scan any number of pages without the interruption of advertisements. The smart eraser helps to remove any unwanted comments on the text. However, there are ads that badge in once you finish an action and before you begin another. Generally, it's a good app.
