The Salesforce mobile apps help your users stay productive on the go.
We added Chatter enhancements, email notifications for cases, and subjects for tasks and events,
just to name a few.
Salesforce App: Predefined Subjects and Chatter Updates
Your users can now create and use predefined subjects for tasks and events that they create on the go. We added more capabilities to Chatter, including polls, questions, and rich text. We've also got improved push notifications coming with the 16.0 app release later this summer.
