Crashes

I have tried several times exporting the data to my email or through fav and the app crashes. When clicking on app support, I am sent to a page that says error

Thanks for your update!

Excellent tools!But when I use it in my clinical works, I always face the problems of merge and synchronization that I must use android device. We hope updates in android!

Experiencing crashing

As of November 21, 2019

The app is crashing on me consistently

What I’m doing is:
1) go to statcalc
2) select 2x2xn
3) if you try to select column 2,3,4,5, or summary
The app will crash

Running on:
iPhone 11 Pro Max
IOS 13.3

Better than before but still needs work

First off, I love that someone/several someone's are working on this!

Still the iApp needs to be able to:
(1) upload forms using a weblink or the ability to design forms within the app - can someone add
And
(2) a function to share the data collected with other devices without overwriting other existing datasets
