Smartphones aren’t an accessory for real estate agents; they’ve become a necessity. However, having the device is only half the battle. To make the most of your phone, you need the apps that turn it into a real business tool.

Check out this list of must-have Android apps for impressing your clients and taking the paper out of a few important processes:

1. Share room layouts and measurements with D-measures

2. E-mail and text hands-free with Dragon Dictation

Newer Androids are starting to come with voice dictation, but those who have an older device can easily add the feature with an app called Dragon Dictation. Dragon Dictation transcribes anything you can speak and allows you to easily send it as a text message or e-mail without touching your device.

3. Track and report vehicle use with TripLog

TripLog helps agents by automatically tracking an agent’s mileage while he or she is driving. In addition, the app also tracks fuel ups and other expenses to give you an idea of how much moving around town is really costing you.

5. Track and display your time with the Harvest Mobile App 

Last but not least, here’s a great app for showing clients you’re worth your commission (and likely more). Harvest mobile app helps you clock your time working on a task or project with just a few clicks.
