What do you like best?
This app has been immensely useful. There have been times when I am not at my desk and needed to fill out some forms and this app allowed to me to do so right on my phone. This is life saving productivity.
What do you dislike?
The only thing I disliked was the many screen you need to go through to finally start using it. Other than that, the app is great.

The business problems this app solves is the ability to conduct business anywhere. You are no longer constraint to your desk or an office. This allows for travel and connectivity almost anywhere.

What do you like best?
I like PDFFIller because it always works, unlike some other PDF tools I've purchased in the past. PDFFiller is my goto tool and will become my exclusive tool once my other package expires.
What do you dislike?
There's a little confusion when saving to my Google Drive. Now and then, the file can't be found there when on my phone.
Recommendations to others considering the product:
I've also used Ecopy for several years and just find PDFfiller to be more user friendly and stable. As I said, it's my goto PDF tool.
What problems are you solving with the product? What benefits have you realized?
I fill in forms, I create forms listing medical issues/histories, electronic signatures are always handy. I also convert to Office Documents if needed.
