Ok, but one minor thing

Every time I close this app, it logs me out and makes me have to sign back in to my account. This is very annoying but other then that it is an amazing app.

Perfect app for monitoring your nests!

Works great at monitoring your nests, and it is so much easier to monitor your nests in the app than on the web!
