Thanks to Tim's promo code generosity (Thanks Tim) I have the iPhone version of this app.
I really like this app. The interface is well designed, clean & easy to navigate. Among it's
many features are a calibration tool, snapshot capability with notes (great for scouting), and
the ability to select multiple lenses for comparison.
I tested the app against a camera & lens & it was accurate.
Two things I noticed about the app that could be improved are...
1. Would like to see a shortcut for lens selection on the viewfinder screen, like there is for camera
2. In the lens selection screen--you change lenses by selecting or deselecting the saved lens choices.
If you deselect a lens, leaving no lens selected, before you select another, the app defaults to the
first lens on the list (a 6mm in this case). So when you choose another lens & return to the
viewfinder screen, you have two lenses selected-the one you chose & the 6mm lens.
These are very minor issues. I have conveyed these issues to the creators & they are going
to look into them. I was impressed by their response time to my communication!
Again, I really like this app, and will use it often!
