I like that my information is saved and I do not have to keep writing over my applications. I can get it quickly when I see a job I want to apply for.

Very useful. Some issues with mobile devices filling out fillable forms and not all the data showing up on the completed form. Loading times could be a little faster. Also, I shouldn't have to give the app approval to access my email each time I upload a new file from my gmail account. Once should be enough, and the connection should be remembered, but it's not.

Fantastic customer service For some reason I needed this and only once. I got the free trial and then forgot all about it until $115.00 was collected from my account, shock horror. All I can say is you have fantastic customer service, I explained my situation and a refund was issued that same day. Both friendly and speedy. Ace by name and by character, much appreciated. 1 star deducted as I would have liked a reminder email when the free trial was coming to an end.

Easy but not so afdordable Not too bad Storage size of pictures. I can use over 50 pictures in the same document and the file will still be very small. This is important in my dirls Constant updates slows down my production and take most of my time
