Plan on the go who to meet and when. It has never been easier or faster to invite friends, colleagues or family. treffn helps thousands of people everyday to meet face to face! It's not another social network but works with absolutely all of your contacts!

treffn uses the Smart in your Phone to make your life easier. It's designed by an award-winning UX designer so it makes life easy for your eyes as well!

treffn makes meeting up really easy, fast and convenient. It is the ultimate smartphone tool to set up those all-important face-to-face meetings. With only three clicks, treffn sets up a meeting for you and sends our really helpful invitations to your guests: All participants will see the meeting’s location, a detailed route, and individual arrival times.

treffn allows for easy communication. It's usable while on the road or in a hurry getting ready. treffn takes care of communicating last minute changes to the location, of unforeseen delays, or adding additional guests, in one easy to use app.

Best of all, our app works with all your contacts, not just other treffn users. All you need to know is your contact’s mobile phone number.
