I spent over an hour on filing. The app took the photo of my W2, and got most info correct, but some it wouldnt detect. Using an iPhone 6+, Id think either my W2 copy was a bit off, or their recognition tech needs a bit of refinement. I ended up inputting my info manually, but not a major problem.
Some fields were glitchy when entering information. Sometimes it wouldnt allow input, but Id click on done, and go back a page, and go forward and then click on field, and voila! It would work. All in all, very good and solid app/service!! Id definitely recommend it, AND being free makes it better.
This was my first time using this app. Last year I used a major competitors app (just use your INTUITion on who it might be), and honestly, it worked great, but cost me almost $30, and I could live with it. But they changed their app, and its much more expensive now, and people are saying much more difficult to use.
