We’re introducing optional subscriptions for OmniFocus.
You don’t have to subscribe, but if you do decide it’s the right way to go for you, then you’ll have a choice:
$9.99/month for OmniFocus for the Web and the pro editions of OmniFocus for iOS and Mac. (All three apps!)
$4.99/month for OmniFocus for the Web. (Best for people who’ve already bought one or more editions of OmniFocus.)
