I have only used this once so far but it was very good quality. I hope to be able to utilize this program often. I just wish it could be put on my desktop.

Easy to use. Haven't found a form it couldn't handle. I had an issue recently where it would not allow me to save a copy of the completed form as a PDF on my computer. Weird. Otherwise 5 stars

I'm learning it slowly. You cannot merge files in the app on ios. I need that. There are also a few hic-ups. Sometimes after a signature the screen gets disoriented and you have to go back to documents list and reopen. Sometimes after reopening some of the modifications are gone and you must re-enter. Some of these issues may be due to not being connected to internet. Overall it has helped me go paperless and I'm getting faster at filling out my documents using it. A few tweeks and it will be awesome.

I am happy I have found your company. I appreciate your east steps to follow. I don't know if I am not understanding how to save each 1500 I complete as I need them to enter new dates as each week comes to bill.

No way to easily add additional pages in a template I used. Had to keep erasing everything to start new page. “Next” button skips all over the page, so this isn’t tablet-friendly. Waste of my annual subscription fee.

Great software. Only thing is that i wish the email could be modified to where i can get paperwork sent directly to it. The automated one we're given is way to complicated to remember so copy and paste it is. Other than that this is amazing software.

My name is Jonathan from Africa My name is Jonathan from Africa, I needed a form via PDFfiller but was unable to use the service and was billed while on 30 days trial. That got me upset but after contacting Shennon online support, I was assisted, and in less than 10 minutes, it was resolved. Shennon exceeded my expectation. Satisfied. Therefore I commend Shennon for a great and wow customer service. Because of this singular act, I will recommend your company to friends.Thank you

I've been very happy with this product! I've been very happy with this product! It has helped me tremendously file insurance claims and do work since my husband has been in the hospital since 5/30/20. I did the free trial but will be purchasing it for the year.

To track period dates, instruct your daughter to put an “X” or another mark on the first date of her cycle. Mark every additional day she experiences menstrual bleeding. Repeat the process the following month. Then count the number of days between each month's first day of flow.
Starting on the first day of your last period, just count out the average number of days between your periods (aka your average cycle length that you calculated) and that gives you the projected start date of your next period.
