About
Zamm is the one app for every event with friends, family or acquaintances: a trip, an outing, a bachelor or bachelorette party, a ski holiday, a hiking week, a wedding weekend, a club outing, or a course like a yoga class. Participants are invited by link or QR code and can then talk about every part of the event in Zamm.
CHAT
In a built-in chat, messages about the event can be exchanged. With replies and reactions.
PHOTOS AND VIDEOS
In a shared album, photos and videos can be shared in full quality. In the evening, Zamm reminds you of the day's photos if you like.
COSTS
Shared costs can be recorded in shares, in different currencies. At the end it shows who owes whom how much. Receipts can be photographed, and the amount is read from them.
PLACES AND LOCATION
On a shared map, the accommodation and meeting points are marked. Whoever wants to shares their location, from two hours before the start until the event ends.
TASKS
In one or more shared task lists, everybody sees who brings what, what is booked and what is still missing.
CALENDAR
The shared calendar holds every appointment of the event. Appointments can repeat every week or every two weeks. Participants say whether they are coming, and Zamm reminds them in time.
COURSES
Courses have a place in Zamm too: for up to a year, with recurring sessions in the calendar. Location and photo suggestions are only on during the sessions.
POLLS
With polls the group decides together, for example on a restaurant or a date.
INFORMATION
The address, the Wi-Fi, the door code and everything else everybody needs to know is in one place.
INVITING
Participants are invited by message, link, QR code or right in Zamm. Even people without Zamm count in the costs, tasks and appointments.
PRIVATE
No account, no email, no phone number. The Zamm backend receives all content encrypted, only participants can access it. No ads, no tracking.
WITH AN END DATE
An event in Zamm ends automatically. Once the event is over, the chat is closed and the data is deleted from the cloud.
