Not for free to send it and save to computer. Almost $7 for a year isn't bad though! But I'm not sure if i'll be using this all the time though throughout the year.

I love this app
I love this app, it makes sure to compensate for all the things which you would need to do for schoolwork. Personally though, I think it would make more sense to market it with ads rather than subscription. This is really useful for students who are homeschooled or aren't able to go to school and students usually don't have much in their pockets to pay for these kinds of things.

Gets the job done!
Amazing, all sorts of adjustments can be made (Text, highlight, signature, templates etc). User friendly and a simple enough design. Cheaper too! My only issue is internet connection, perhaps if it was available offline (I'm not sure if that's a feature or not), it would honestly replace Adobe Acrobat all together.

customer support
I had cancelled my subscription but it had not gone through and was charged. I explained this to the customer support team and they helped me very nicely and gave me a refund. It was efficient and very understanding!

A great online software, easily linkable with Google Drive. You can modify as far as you want your documents, make signature and so much modifications.
