Across Google Play and the App Store, Google's Firebase Cloud Messaging SDK led all push messaging SDK installs in the month of May. The ability for brands to send timely and effective notices to their users' mobile devices is one of the most important factors in creating more engagement, retention and conversions.
OneSignal is the next most popular push messaging SDK to be installed by mobile apps seeing to communicate with their customers. Like Firebase, it's the second most popular for both the iOS App Store and the Google Play Store. After that, the SDKs diverge in their rankings on both stores but a lot of the top players for iOS are the top players for Google Play as well.
Many of the SDKs found on this list and in this category do more than push messaging. Apptopia's SDK Intelligence enables you to sort SDKs by several categories, including push messaging.
