Easy to use, Syncs well between iMac and iPad/iPhone

I really like this app. Not too complex. Nice to use for mobile and portbale work with iPad and then sync back up to Mac desktop. However I have had the persistent problem of the “time” in the log page be UTC but displayed as local time. So at 5:00PM Mountain time (00:00 UTC) the time in the log page for a new contact is 12:00AM. So the time for the contact is wrong as it is not shown as UTC or, the proper local time. I have tried to find settings for OFFSET FROM UTC but, can’t find one. So, I’m forced to correct and manually enter the time for every new contact. Am I the only one?

callsign lookup needs bug fix

when I am creating a new contact the callsign lookup feature within the new contact window sometimes retrieves the wrong name, QTH, & State when I click the "Look up" button. Please fix ASAP. Thanks & 73!

Nice application but RAM hog

This is a nice application with a lot of helpful utilities especially for a new radio operator like I am. For the price I think it is a great value. One warning though. This application has been troublesome on my 2013 iMac in terms of RAM usage. My new computer slowed down to snail speed after I installed the program but I didn't make the link at first. I finally got on the OS Activity monitor and noted that the application was using 3.24 GB of RAM! Maybe this problem is unique to my installation but if you install this application and then notice your computer has slowed down, This app could be the culprit. But for that I would give this App a 5 star rating for the price.
