Push Notifications by One Signal

Push Notifications cannot be tested with the Thunkable Live app on iOS You can test Push Notifications on iOS by publishing your app to TestFlight and downloading it from there.
One Signal is the world leader in push notifications and they offer their service for free.
Push notifications are one of the biggest advantages that mobile apps have over mobile websites, since they can send messages to users without the app being open.
However, annoying notifications---those that are irrelevant and too frequent---can be dismissed or blocked easily. We highly recommend sending notifications only when the content is relevant to the user. Examples of this include an e-commerce app notifying users of a sale, or a game notifying users of new levels and features.
Push Notifications are a
component. While all Thunkers can add Push Notifications to their app projects and live test them in their apps (Android only), only PRO Thunkers can download and publish apps with Push Notifications.
