Just as with the timer function on the actually web app for invoices, you can’t enter notes while the timer is running. This is frustrating if you want to keep adding notes as you work. HOWEVER, with this app, you can’t edit a time entry after you hit “Stop.” Very bad! * Can’t delete an entry. * Can’t add notes after stopping. * Can’t manually adjust the time on a time entry. I was really hoping to get a small app to use when doing work so I didn’t have to log into the website all the time. Unfortunately, this was not it.
