Go beyond simple text messaging. Show the world how to add innovative messaging capabilities to deliver a more interactive and engaging mobile experience. We want to challenge developers to dream up and power new, mobile first apps with our recently launched Magnet Message framework. We are prepared to reward you with cool cash prizes!

What is Magnet Message?

Magnet Message is a powerful, open source mobile communication framework enabling real-time user engagement for your iOS and Android mobile apps. Magnet Message has the features you need to add better, more personalized interactions to your app. The code is free to download and Apache open source. It includes a ready-to-run server and native mobile SDKs for iOS and Android.

For this challenge, you will be able to leverage our new cloud-hosted Sandbox supporting the following features:

  • In-App Messaging (includes 1-to-1 and 1-to-many)
  • APNS & GCM Push message integration with wake-up
  • Publish/Subscribe
  • User or app directed messages and events
  • Rich message payloads (text, image, HTML, JSON, etc.)
  • Confirmed message delivery status
  • And so much more!

What can I build with Magnet Message?

In this challenge, we want you to showcase what is possible with Magnet Message. Think outside the box. Go beyond simple text messaging. Think about how mobile apps can truly benefit from more personal, interactive and intelligent communications – both one way and two way. Get those creative juices flowing! Amaze us with your submissions!

For the challenge, we need you to explore at least one of these interactive scenarios for your hack:

User-to-User and/or User-to-Multiuser Messages - leverage embedded chat within the app, so that users can interact via reliable two way messaging in real time.

Ad hoc Discussion Group – enable ad hoc discussion group capabilities within the app, so that users can create a private thread or category and share updates with a limited group of invited users.

Public Forum – create a public forum or feed with publish/subscribe, so that users can openly interact with one another around a given topic.

How do I start?

To get started, check out the Resources page for links to useful information including an overview of Magnet Message, links to the Sandbox, Getting Started guides for both Android and iOS, API documenation and access to sample code and apps.

If you have questions or need assistance, please use the Discussions page for this challenge or our Forums. You can also Contact Us on Magnet.com

Good luck to all the participants!
