Not for me then I'm afraid
Aworka works on Apple.
It's cloud based with a monthly or yearly fee. I think it was developed with the guy who owns George so there are a lot of its features
I was with George for 6 years but went over to aworka so I could email customers invoices and run the round paperless from the iPhone or iPad.
Yes its a small yearly cost for very up to date user friendly, efficient software.
