I have been using the app for awhile now with no issue. My last 2 outtings I have had the app lock up while trying to log a contact and all I could do is restart my iPad to get it to function again. I didnt loose any data. I did take a pic of the last qso that would not save so when I restarted the app I could log the contact. I am using an iPad air with os 15.7 running.
