CallSky is an iOS app that lets you make international calls to regular phone numbers in over 180 countries. You buy credits through the app ($4, $8, or $16 packages) and use them to call landlines and cell phones at rates starting from just $0.01 per minute. The person you're calling doesn't need the app or internet - it rings on their regular phone like any normal call.

With Skype shutting down in May 2025, CallSky fills the gap for affordable international calling. There are no subscriptions or monthly fees - you only pay for the credits you use, and they never expire. The app shows you the exact rate before you dial, and calls use premium carrier networks for crystal-clear quality.
