Its great, I am pleased to have this application on my tablet and phone. Need to work out the kinks for the phone. Overall it will do the job! Very appreciative.

it does important essential legal functions in ways that work but are somewhat visually disorienting and that are provided through a user-insensitive, extortive pricing model.
The fact that PayPal has removed you from their approved subscription list may be entirely technical but it does not inspire confidence.
2016-06-19
Great program and a much better value than Adobe Acrobat! Pay for the features you need instead of hundreds of dollars for features you will never use.
2017-07-07
It was a little tough figuring it out at first, but it seems to be doing exactly what I want it to do. In the sending and returning process, I think it could be done with perhaps fewer steps
2018-09-26
Hard to get used to, and probably a lot of features we are not taking advantage of for lack of know-how, but very reliable and handy. We mostly use it to send for signature.

PDF filler that will empty your pockets.
The most accurate file editor. The most reliable document converter. The master of alterations.
I can email important documents immediately upon request. I can edit and sign government documents that are lifesaving for important life necessities. I.e. rental arrears. Rent ledgers. W2 forms, etc.
The darn subscription is too expensive just to use for once a month, or only when necessary. They should have like, one time prepaid options instead of monthly or yearly.
2022-06-22
Great service
Great service, and offered and processed a refund within minutes of me not needing my subscription anymore. Will definitely be coming back once I need their services again.
2020-12-15
Adapting from working home, I needed to make forms fillable to get signatures and this service was exactly what I needed!
Even after I forgot to cancel my subscription after the free trial, their customer support was auper responsive and able to refund the autopayment.
Thank you!
