What the mobile app is for
A field rep does not have a desk. Their working surface is a phone held in one hand while standing in a shop, a plot, a factory corridor or a hospital corridor. A CRM that assumes a keyboard and a quiet half hour will be updated from memory at ten at night, and everything downstream of that data will be slightly wrong.
The mobile app exists to move data capture to the moment it is accurate. It shows the rep what their day contains, opens the customer with the history that makes the conversation better, lets them call or message from the record, and takes the outcome in a few taps before they walk to the next appointment. That is the whole design brief, and features that get in the way of it are a liability rather than an addition.
