Sync iMac to iPhone
I have your your professional version on my iMac under your extended 30-day free trial. I also have the standard version on my phone.
I intend to continue with your program, I love it.
How do I sync the two and upgrade the iPhone version so that they match? And is there a separate charge for each version/
The Premium status is based on your account information. So if your iMac desktop app is Premium, so should your iPhone version. Please try logging out and back in again on each, and it should sync just fine.
Just head to http://www.todoist.com and in the top right corner, click on the gear icon, and then Todoist Premium. From there you can upgrade :)
