Push Notifications by One Signal

Push Notifications Overview

One Signal is the world leader n 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 include an e-commerce app letting the end user know about a sale, or a game app letting the user know about a new level or feature.
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 Thunkers with PRO, Business or Enterprise accounts can download and publish apps with Push Notifications. See our pricing page for more details.
