2★I'm really mixed in my opinion of the company rather than the app itself. The app worked well for the one instance I used it for however it was certainly not worth 27.99/year. For someone like me, who works 60-70 weeks and can barely keep my calendar of appointments straight, I had a feeling I was forgetting something. I guess I'm just really disappointed in how much money you charge for something so simple. You should just give people the option to hit a button to cancel a trial, not email you.

1★This app was very frustrating to use. I got it exclusively because I was short on time to sign a document on my phone. It took a bit to get the hang of how to edit and undo something. But the most infuriating was when I spent over an hour writing in the details of my form only for it to not show up on the form I emailed to myself. I just wasted all of my time... I will not be using this app again.

3★Positives: Ads are minimal. I can turn an image to PDF in a minute. No watermark on the final output. Simple interface. Negative: I'm not sure when this started, but now Image to PDF is always trying to crop my image when it doesn't need it. Now I have to go through this extra step to un-crop it. Either auto-crop correctly or don't automatically apply it to my image please.
Nicola Bahr
1★An excellent app is now trash! I've had the FULL, PAID version of this app for YEARS and found it invaluable. It scanned multiple page documents and was ad-free. No more! Now, the PAID app only takes single page scans and is full of ads that make using the app slow and annoying. Stay away! Even if you paid for the full app before, they now demand you pay again with an ONGOING subscription. I ALREADY PAID for the multiple page scanning feature. I refuse to pay again. Somebody got greedy.

1★Downloaded this app with a 7 day free trial. On the 7th day when it was still supposed to be free it charged my card for a year. Ive sent emails with no response for refund. On top of i dont even know how to use this app. I needed to fill out paper work and email back. It took me forever to fill it out due to how its set up. Fo not download this app!!!!!
