There was an iOS app I used like this that did a great job of scanning text books.
After I used it for about 6 months this exact thing happened. Started charging fees for many different things.
Exporting images as pdf had a charge, then scanning to make the text searchable had a fee.
I just exported as jpg and used imagic and ocrmypdf to take care of this.
Then I learned that iOS has a built in scanner in the files app, so I just switched to that one.
This is going to have a much bigger impact on the third would countries.
Most people here are not going to buy a new computer there are tons of people who buy second hand laptops that are old to be able to afford them.
Additionally people are not tech savvy and don’t understand the implication of this. When they see an ad that says to buy a new computer, they are going to dismiss it the same way they dismiss all the other ads online telling them to buy stuff.
