The az list app displays hundred contacts per page without scroll down on the screen of your device.

The app only retrieves name, phone number and profile photo’s URI from your contacts list and doesn't permanently save them in any storage. When you exit from the app the information will be removed from the app.

Users can make phone calls from the app activity through a dialer pad of the Phone app’s.

How can I make a phone call/text message from the app?
- Tap a contact's image view and it prompts activity names the user can do
- Tap ‘1. make phone call’ it brings the dialer pad of the Phone app
- Tap the ‘2. Call’ button for starting the activity

If you tap on ‘send message’ activity, it starts the activity through the Messages app. If you have not installed the Messages yet, you can get it from the Google play store.
If you tap on ‘3. dialer pad’ activity, the dialer pad pops-up with suggested contacts to call based on your call history.
