App is very limited to what you can do, log entries double up all the time, editing log entries are impossible, if you miss a jump and enter it after other jump they are left out of order, support is a joke. I've contacted them many a time only to receive empty promises. DON'T WASTE YOUR TIME!
Don't bother App is restrictive on what information can be entered. Log book entries doubled up. I have contacted support but have not heard back. Waste of money when free app, Skydiving Logbook is better.
