Show HN: Callzo – I built this to call home when I land abroad (callzo.io)

Every time I land at an international airport, first thing I want to do is call home. Just to say I'm here, I'm safe.

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.
