One of the worst things an application can do is to destroy or corrupt your data without a soft reconstruct/edit capability.
We all know that this product s a great idea, and we all know that defects are sometimes difficult to quickly replace.
But TIME marches on and there gets to a point where the Developer needs to recognize that it's time to spend the bucks and make the repairs.
Now I don't know what relationship these app developers have with Apple, but let me say here that this App is not responsive (i.e. issuing updates) as it is expected in order to maintain a level of minimum quality, and if they cannot, Apple should read them the RIOT ACT. This is not tolerable.
At this point my recommendation to all of your who are considering this product to not spend the bucks until this is truly more reliable. As it was, as currently delivered, this is half of a product. It cannot be relied on. My suggestion is to spend no more effort than you think your $100 commitment has been until AUTHinq comes across with a decent functional and reliable upgrade. Believe me, I have spent months with it and it was nice and convenient (not irrreplaceable however). But when your assignments and correspondences of room and devices get corrupted and there's no other way but starting over, one begins to wonder why you ever started up with these guys.
I'm talking to all you potential users and to AUTHINQ. AND APPLE. FIX IT or DUMP IT.
