Important note! You can still purchase separate licenses for OmniFocus for Mac and iOS — you don’t have to subscribe. Subscriptions are optional, and they’re not the best choice for everybody.
But, if you are considering a subscription, you should know that for $9.99/month, or $99.99/year, you can subscribe to OmniFocus Pro for Mac, OmniFocus Pro for iOS, and OmniFocus for the Web.
For more information about subscribing, read Subscribing to OmniFocus, which covers all the options.
If you have additional questions or need help, please contact support. Thanks!
