why in the hell do I run into 3 different ad spaces just trying to load one book? Am ad when I start the app. an ad when I click on the book. then, when that doesn't load the pdf, ANOTHER ad to make it work? you're app does little, but you're trying to charge ppl like it's an interactive game. Have begin searching for an alternative, and I think I've found one. to anyone else using this app, once it fricking loads it's fine. But it forces you to work to get there. In my opinion, for a simple PDF

Hi dear user, sorry for the inconvenience. Ads help keep the app free and support our team, but we’re working to make them less disruptive.✨ You can also try the paid option to remove ads if you like. Thanks so much for your understanding and support!

Click-Bait. Says the app is #3 in the top free. False. Once you open the app, it wants your payment info to pay for a subscription service. You get a trial period only after you input your payment info. After that, you're getting billed with the subscription unless you go through the complicated process of canceling the reoccurring payments. That's pretty shady. I downloaded it and instantly deleted it. So, this just wasted my time. All because I wanted to view 1 image and not get suckered.

Hi dear user, we're sorry for the confusion. You can close the pop-up by clicking the 'x' after a few seconds. We understand your concern. Maintaining the app requires funds, but the paid version is completely optional, and you can still use all the basic features for free. Thanks for your support!😊

Excellent implementation of a PDF reader. I don't really mind the pop up ads. I understand the necessity. But an ad for a 30 day workout keeps popping up, and even if I follow the ad to the web page it opens, when I try to get back to the app, the ad pop up will not go away. So I literally have to kill the app and restart it to get back to my files. I had high hopes ... Alas I guess it's not meant to be.
