Домофон is a free Android application developed by PIK-COMPANY, which allows you to open doors with your smartphone. With this app, you can receive a call from the doorphone on your phone and see who is visiting you. You can then easily open the door for them with just a few taps on your phone.

This app is an excellent solution for those who want to open the door in the hallway, on the floor, and fire exits. With Домофон, you no longer have to worry about missing visitors or having to rush to the front door. You can open the door from the comfort of your home or anywhere else, provided you have your smartphone with you.
