It is somewhat confusing at first, but after learning the program it is very helpful and convenient to use! I enjoy all of the different options regarding the tools to fill out a PDF, for me it was a rental application for an apartment that i needed to fill out. The one thing I did not like is that after i had filled out my entire application via the pdffiller app, i could not e-mail the pdf until i paid for a plan. Somewhat disappointing, but regarding the program it is a good one.

SIMPLE AND EASY TO UNDERSTAND FOR PEOPLE WHO ARE NOT TECH SAVY
ITS GOOD BUT PRICE SHOULD BE MADE RESONABLE SO THAT MORE PEOPLE CAN AFFORD AND USE YOUR TOOLS. FOR PEOPLE IN INDIA IT IS STILL EXPENSIVE. IF YOU REDUCE YOUR PRICE, IT WILL BE AFFORDABLE TO MANY AND YOU WILL HAVE MORE CUSTOMER VOLUME IN INDIA THAN ANY OTHER COUNTRY. THIS WILL HELP YOU GENERATE MORE REVENUE.
