PDFelement - Is it a scam app?

I have been looking into this app but something about it is rubbing me the wrong way. It feels very much like one of those apps that was purchased by a large company coughevernotecough just to lure people in to ridiculous subscriptions.

Does anyone have any experience using this app?

It’s a typical Chinese app. It’s not scam per se but don’t expect artisan indie app quality.
