Build your own mobile app for Microsoft Dynamics CRM on Android, iOS and/or Windows.
Start with the Mobile Focused area of the Microsoft Dynamics CRM Developer Center.
One of the big areas of development for the Microsoft Dynamics CRM 2016 release has been mobile! Consider multiple operating systems (Android, iOS Apple, Windows), distributed processing (The Power of Azure and the Cloud) and a giant world of choices (One person with an Apple phone, another with a Windows Tablet). Microsoft has always been good at offering a ton of choices.
So you can use all of the choices offered by Microsoft OR you can dive into creating your own. If you align with the team, you leverage the SDK and you write awesome code, the world is yours for the crafting!
