CallingPost doesn't have a native mobile app in the traditional app store sense. However, you can easily create a shortcut on your home screen for quick access, making it feel like an app. Here's how:
Android:
Open Google Chrome.
Go to apps.callingpost.com.
Log in with your User ID and PIN/Password.
Tap the three dots (menu) in the top right corner of Chrome.
Select Add to Home Screen.
(The option might also appear at the bottom of the screen).
Tap Add on the confirmation pop-up.
The CallingPost icon will now be on your home screen for easy access.
iOS (iPhone & iPad):
Open Safari.
Go to apps.callingpost.com.
Log in with your User ID and PIN/Password.
Tap the Share icon (square with an upward arrow) at the bottom of the Safari window.
Select Add to Home Screen.
Tap Add on the confirmation page.
The CallingPost icon will now be on your home screen.
