kommtihr

In progress

A shared calendar for families who know each other: see who else is going. Waiting list open, the app is in progress.

The kommtihr landing page on a coral-red background: “Kommt ihr auch” (“Are you coming too”) in large type with the line “Endlich eine Antwort.” (“At last, an answer.”), next to a card showing the autumn fair in the park, four families coming and a “Wir sind dabei” (“We’re in”) button. The interface is in German.

Anyone planning a weekend with children first looks for events, copies dates by hand and then asks around who is coming. In the end it is often still unclear whether familiar families will be there. kommtihr answers that one question: which of my people are going too?

The groups are small and closed: a nursery, a circle of friends, a club. kommtihr is not out to replace WhatsApp. Everyone is there anyway, but dates get buried in the chat. kommtihr wants to be the place you link to from there, with a preview such as “4 families are going”.

So far the planning, the look and the landing page with its waiting list are done. The page is built for the phone first, with a light and a dark theme, and counts nothing. The app will come as an installable web app; until then you can sign up. I made the sample flyer on the landing page with my own image generator.

Decisions

Every group on its own

An event belongs to exactly one group, such as the nursery or a circle of friends, and only its members see who is coming. Anyone who wants it in a second group copies it across, and the copy knows where it came from. That way nobody has to worry that the nursery can see when they are out with friends.

Children by age group only

A child has an age group and, if you like, a first name or nickname, nothing more: no date of birth, no photos. That is enough to answer who is coming, and the data that needs the most care stays small.

Signing in without a password

Anyone who is invited opens the link, sees the event without an account and says yes with a tap. After that a first name and an email address are enough, and a link by email confirms the answer. There is no password, so there is none to forget.

This site in a different design

Same content, different look. You start on its home page, and every link stays in the chosen design.
