My initial thoughts on the ap so far:
It is easy to use and easy to setup. Everything is user friendly
It is very lacking in breeds in "My flock". Most of mine are not listed.
I like that it asks for a hatch date, but wishes it displayed your chickens age once date is entered as opposed to just the hatch date.
Love the egg tracker! however, I do wish we could assign an egg to a specific chicken. For people with smaller flocks, it is really helpful to know who laid on what day.
I will come back in a week to add the rest of my review!

The above still stands. It is a bit buggy. randomly shutting down when it wants, etc. It has potential to be a great app once everything is worked out
I agree that an incubating calendar/reminder would be handy. Does not need to be fancy...just set dates, lockdown dates and hatch dates.....
