What is JA! Reisen?
JA! Reisen is a group-trip planner for travelling with friends, family or a club. Plan the itinerary together, see everyone’s live position on a map while you drive or ride, and split shared expenses without spreadsheets or awkward IOU math. Everything you share — the plan, your live location and the expenses — is end-to-end encrypted on your device, so the backend can never read it.
It’s free, ad-free, and built for the road: invite people with a link, hand a checkpoint to your navigation app, and settle up when the trip is over.
See the convoy
Live positions on a map with order, gaps and pace — so nobody gets left behind on the road.
Split & settle
Multi-currency expenses, fair splits and minimal-transfer settle-up, with CZ/SK QR payments built in.
Invite by link
One link brings someone in. The decryption key rides the link fragment — the server never sees it.
Encrypted end to end
Itinerary, expenses and live location are encrypted on your device against a per-trip key.
Free & ad-free
The whole app is free — no ads, no paywalls, no selling your data. Just an optional tip if it saved your trip.
Private by design
Most apps ask you to trust their servers with your movements and your money. JA! Reisen is built so you don't have to — the backend is zero-knowledge and can't read your trips even if it wanted to.
