Horizon Calculator

Horizon Calculator calculates the height to the horizon from a certain height, and vice versa.

The app supports both metric and imperial units.

* Caller ID

Horizon Calculator has free caller ID. It identifies callers for you - even the ones not in your contact list. Caller ID results are shown after calls and also allow you to save the contact details directly to your address-book. You can always go to Horizon Calculator with one click from the Caller ID screen.

You can disable or adjust caller ID to your preferences in the app menu settings or after-call screen settings at any time.
