Reliable App
I don't care for the most recent change to the forms that moved the text all the way to the left or right depending on the field. The text should be on either one side or the other, not alternating. In addition, it's difficult to edit text when it's all the way to the edge of the screen. My tablet has arrow keys which allow me to position my cursor, but a the keyboard on a phone only has a backspace key.
Other than that, FastField Forms is the most bullet proof app that I've used. Glitches are rare and power cycling my tablet usually fixes it. I've been using FastField since May 2018 and there is a learning curve but tech support was very helpful. Since getting it setup and live, I've only called tech support a couple of times and each time they addressed the problem in a very timely manner.
Once you know how it works, making changes is straight forward. I've made several changes and tweaks to the main form that I created and it is easy to do.
