I have been a professional photographer for 20 years and have relied on Photoshop as my main editing tool. Often I find myself exporting phone pics back to the desktop to edit because I cant do what I want on the phone.
Handy has changed that for me. The retouching (healing) option is very good, and the smart crop works well. Being able to do selective area adjustment and having a smart selection tool like this app has make me go back to my desktop editing far less than before.
I do have two dislikes for the app though. One major and one minor.
My major complaint is that when trying to select a photo to work on the gallery view thumbnails are too small to see any detail at all, especially if you are like me and shoot multiple versions of each shot.
The minor complaint is the magnification window that pops up when using the selection brush comes up on the left side of my finger. I am left handed and my finger always ends up blocking my view (partially) of the magnification tool. Being able to have a preference menu to set for right or left side display would be very useful.
