Dropzones are a location-based version of Apple’s “Downtime” feature. Want to use Dropzones at home? Simply choose a category of apps you want to limit (e.g. social media), then type in your home address. Now, whenever you’re at home, your phone will automatically limit access to your social media apps. Dropzones are also useful at school, work, or any other location where you want to auto-unplug. Animation below made using Principle.
2020 Update. Apple introduced a similar feature called Dropzones in their Shortcuts app.
