FOUR COUNTRIES · SEVEN DAYS
Four strangers, four countries.
One 10-second video a day, for a week.
Carism matches you with three strangers from three other countries around a topic you both live every day. Each of you posts one 10-second clip a day. Seven days later, you've seen the world.
Launching soon on iOS and Android.
HOW IT WORKS
Seven days, three steps to start.
STEP 1 OF 3
Pick a topic
Choose a slice of your everyday — morning routine, home cooking, a daily walk. In a hurry? Hit Fast Random ⚡ and match with anyone.
STEP 2 OF 3
Meet your group
Carism forms a private group of four — you and three strangers, each from a different country. No followers, no feed, just four people.
STEP 3 OF 3
Share 10 seconds a day
For seven days, everyone posts one 10-second video of the same everyday moment. Watch the group's room fill up, day by day.
THE ROOM
One room, four countries.
Your group lives in a 2×2 split screen — one quadrant per country, playing everyone's clip for the day. Tap any quadrant to go fullscreen with sound, and swipe through the day's videos.
WHAT YOU GET
Small by design.
Truly global matching
Every group is four people from four different countries — guaranteed. Your daily walk meets someone else's, half a world away.
Topic groups
Reading, workouts, journaling, home cooking — groups form around an everyday activity, so there's always something to film.
Fast Random ⚡
Skip the topic and match instantly with three strangers. One tap, one new group.
A 10-second camera
The in-app camera records up to 10 seconds in 1080p, with pause and resume. The limit is the point — no editing, no pressure.
One clip, many rooms
Record once and share the same clip to several of your groups at the same time.
Simple sign-in, free to start
Sign in with Google or Apple. The free plan includes two ongoing groups at a time.
TOPICS
Everyday things, everywhere.
Groups start from the ordinary — that's what makes them worth watching in four countries at once.

FAQ
Questions, answered.
What is Carism?
Carism is a mobile app that matches four strangers from four different countries into a private group. For seven days, each member shares one 10-second video a day around a shared everyday topic, and everyone watches the group's clips side by side in a 2×2 room.
Is Carism free?
Yes. The free plan lets you be in two ongoing groups at a time. A membership with more room for groups is coming later.
How does matching work?
You pick a topic (or choose Fast Random for an instant match) and Carism forms a group of four people, each from a different country. Groups are private — only the four members can see the videos.
What if I miss a day?
Nothing breaks. The group's seven-day cycle keeps moving, and you can jump back in the next day. The rhythm matters more than a perfect streak.
When does Carism launch?
Carism is launching soon on the App Store and Google Play. Check back here for download links.
