Giving away my app to friends

I wanted to give my little app to some friends by Google play.
But as I realized that there is to pay 25$ for registration.
So I sent them the apk-file. But as they are not familiar with the Smartphone they could not install it. Is there an easy solution free of charge to distribute an app.
As I don't want earn money with an app, I either don't want to pay for giving it away.

Personally, I built a webpage at and posted the APK object in a .ZIP folder. If you want, you can see it at:

Install instructions are at the bottom of the page.

Je ne comprends rien du tout!

What happened when they tried to install it? You can send them the apk via whatsapp or telegram. That works.
