Daysy not syncing with Daysyview

Given this is my first attempt at trying to sync my daysy to the downloadable app I don't have much to compare it to. Opening the app alone I've taken notice to how many times it closes out of itself. I'm seeing there was an update on 9/28/16 for minor bug repairs but it looks like there are still some issues that need to be resolved. I have tried several times today after familiarizing myself with the owners manual, video tutorials and FAQ to load my information on to the app from my daysy and there is no message notification that pops up as displayed in one of the daysy tutorials. My day reads "no data". I understand that daysyview is not needed to get a read for the day, I find it a bit unfortunate considering the cost of daysy and that I am unable view something as basic as my temperature since there is no LCD screen on the daysy machine itself, I would expect to refer to the app so I can read my information. As mentioned above, this is my first attempt, and I may be doing something incorrectly but this is my first experience that I would like to share.

A lot of app crashes

I haven't purchased Daysy yet because it has been on back order however, I downloaded the app to get accustomed to tracking. I have been using the app to manually enter my temperatures and menses. I have experienced a lot of app crashes which worries me for when I actually purchase Daysy. There is no screen on Daysy itself so it'd be frustrating having to depend on the app for tracking if it's constantly crashing. The app has a great design and is easy to read/use but what's the point of it constantly crashes! I think I might splurge and spend a little extra to get the LadyComp (which is also from Valley Electronics) because all the information is stored on the device itself.

Needs work!

Crashes on IOS 9. Otherwise, great concept.
