Yolla is a popular pay-as-you-go calling app that connects to real phone numbers worldwide. It works well, but it is built around a mobile app and its own account, which means installing software and going through onboarding before you can dial. If you would rather not add another app — or you want to call from a laptop — Hyallo runs entirely in the browser and starts you with a free first call.

Yolla is an international calling app for iOS and Android that lets you call any landline or mobile number worldwide using prepaid credit, with no SIM card or contract. It is widely used by people who regularly call family and friends abroad and want lower rates than their mobile carrier.
The usual reasons: not wanting to install yet another app, preferring to call from a computer, or wanting a clearly free first call to test quality before paying. Hyallo is browser-based and gives you that free first call, while still reaching the same real phone numbers in 200+ countries.
Both are pay-as-you-go services that call real phones worldwide at low rates. Choose Yolla if you want a polished mobile app on your phone; choose Hyallo if you would rather not install anything, want to call from any browser, and like that the first call is free.
