# On a Phone or Tablet

## Overview

The mobile app (Crisisworks Mobile) works with modern Apple iOS and Android devices, both phone and tablet, for use in the field.

It features a mobile-first design which means that it works as well with small screens as large screens. It also means that you don't need to use the mobile app to access the majority of the system functionality, however it is highly recommended to use the app if you can as it features native to the device.

Such features include:

* Familiar functionality to the web version designed for access from smaller screens
* Simple interface for easy use in the field, particularly for inspections
* Easy touch and multi-touch controls
* Use of the device's camera and gallery to capture video
* Access to the device's location for real-time tracking and routes
* Watermarking photos for evidence with date and location. To enable photo watermarks, your system must be configured for this a per register basis. [Contact the Service Desk](https://docs.cw.crisisworks.com/security-and-support/maintenance-and-support/accessing-support) to enable this feature.
* [Offline](https://docs.cw.crisisworks.com/concepts-and-fundamentals/mobile-app/working-offline) functionality, including downloading asset database, forcing offline mode and saving items for offline use. Offline functionality greatly assists inspections in areas with poor or no mobile data coverage.

No special positions are required for the mobile app, however custom functionality is based on the modules and registers enabled for your organisation. Your organisation may also have a tailored version of the app supporting functions such as Mobile Device Management (MDM) and Single Sign On (SSO) - check with your System Administrator.

For power use, such as coordination and administration it is recommended to use the web interface.

{% hint style="info" %}
It is recommended that mobile users, particularly those that require System Administration access, are familiar with both the web app and mobile app as they share similar features and terminology. The mobile app lacks access to some key areas such as System Administration, filtering and querying that can be useful to administrators, coordinators and power users.
