Glad I am not the only one.
I found this software through a review.
I am so happy that it supports auto routing for both windows and IOS.
And its free for 10 PCs.
The desktop app is excellent, i love the layout.
I was eager to test the IOS app but it crashes as the OP mentions.
I know its part of the dev process. I already rated you 5 stars on the Appstore - and i didnt even try it.
So hope it gets rectified soon!
