But my family isn't always online on WhatsApp. And calling normally from a foreign SIM costs a lot for an international number.
I built Callzo for that. Nothing like rocket science or latest AI buzz. Open a browser, call any number, done.
Tried it on my Japan trip. Called home when I landed. On the way back, a friend wanted me to check iPhone prices at the airport — called him through Callzo while I had Japan's internet running. Whole trip, I didn't even use 10 minutes.
That's what it is. Not an app you open daily. Just something quietly sitting there for the moments that matter — when you need a normal call to go through and your usual options don't cut it.
