Easy to dial a number, and then call using your iPhone. (You have to set up FaceTime on your Mac beforehand.)
Enter phone number manually via Mac keyboard or on-screen virtual keyboard. Hold 0 button to enter “+”.
Numpad recognizes country calling codes, and shows a country name on top. It even recognizes an identical dialing code for US/Canada, and Russia/Kazakhstan phone numbers.
On launch, the app will try to paste a phone number from the pasteboard. If there is not a phone number there, the app ignore it.
Numpad doesn’t collect any user data, address book contacts, or anything else. It even makes 0 network requests. Everything is offline.
