Felt like I got ripped off..
First of all, you have to choose your photo type: either US, UK, Canada, etc. Unfortunately, the finish product always indicates the photo is for a US passport. You also need to make sure there is a lot of space around your photo since if you zoom in on a photo, the app will crop the photo to something less than 2" x 2". Once your photo is shown, there is an initial "stickiness" to the feel of the app. It doesnt seem you can move the photo unless you resize it first by pinching. Overall, I feel it is not worth the trouble to download. There are other apps and I regret downloading this app.
