Limitations on the Watch
You need to use a Mac or iPhone for some things
While Fantastical’s Apple Watch app lets you do a lot from your wrist, there are a few things you will need an iOS device or Mac to do. For example, Fantastical uses task and event lists synced from your devices to your Watch. You will need to create these lists either in the Fantastical app on your Mac or iOS device, or sync them from Apple’s Reminders app. Fantastical works really well on the Apple Watch, and it gets an extra boost if you have put in the work on the iOS or Mac version beforehand. Do that and you will have a great productivity set-up.
