Overall, it was good. Saying it is free is misleading. I understand marketing, but I spent A TON of time filing out a document only to find out the only way I could retrieve it was to pay for a subscription which I would then have cancel to make it "free". The other issue was that when the document was converted it shuffled page 2 with page 3 and the only way I could correct it was to upgrade the subscription. I would not spend the additional money when I print it and scan it back in the correct order. Again I'm sure it was an additional money making opportunity for you, but not worth the cost for me.

So far it has worked for what I need. I wish there was a better price for non profit corporations. AZ Exotic Bird Rescue, Inc. is a 501c3 charity but I had to buy myself because of the cost.

You need t tell people that if they enter numbers with commas, the IRS filing process does not work. After lots of time and trial/error, I stumbled across that as the cause of my problems.

Seems ideal for filling Apps. Better than Acrobat Pro. While I have only played in the app for about 15 minutes, I very much like the tools provided for completing forms. In fact, they are superior (for the purpose of form completion) to those available in Adobe Acrobat Professional. They are far more intuitive. Once I get more time in, I will likely increase my rating to five stars.

Life made easy If you fill a lot of forms, it is worth it. Otherwise you might not want to pay for the subscription for just one form. It makes editing and filling out forms so quick. The tools are great and the UI is easy to use and clean to look at. Once you fill the form, you have to pay or else you cannot save or print. This is not made clear from the start.

Best Friendly user software It was great, very useful when it came to modify and add wordings to documents or even signatures. I like the availability to modify and edit your documents, it's very easy to use and it has so many features to get your documents corrected, sent, faxed, emailed and more. I didn't like when adding texts to your documents, sometimes it will freeze and close the program. Then again it was the free trial.
