Mindoo Cairn puts pins, photos, sketches and areas on one shared map for your whole team. Every device keeps its own copy, works offline and merges its changes as soon as it meets the others again.
From relief teams in remote crisis areas …
Field teams keep mapping without mobile coverage. When two devices meet, they exchange what they know, directly and without a server.
… to the oak in front of the town hall.
Zoom in from the planet to the street: every tree, hydrant and playground can carry its own record, inspections and photos.
One map. Every detail. Always in sync.
A workbook is a layer on the map with its own purpose, its own colour and its own readers. Pick a kind when you create it, and Cairn brings the forms, lists and reports that job needs.
Map trees and whole stands after the FLL guideline. Trees are coloured by inspection status, the list filters what is due, overdue or never inspected, and measures go through a four-eyes approval. Inspection records and lists come out as PDF.
In crisis areas around the world, relief teams record what they see with tactical symbols, status, counts and triage categories. Peer-to-peer sync keeps everyone in step when there is no server and no mobile network — devices merge their changes the moment they meet.
Set up an inspection workbook for playground equipment after EN 1176-7, fire hydrants, nest boxes or any other asset on the map. Checklists, intervals and measures make sure nothing is forgotten, and QR labels mark every object on site.
Meeting points, stands, first aid, routes and closed streets: sketch the plan together, add a legend and print it as a poster. Every helper has the same picture on their phone on the day.
Plan stations with riddles, location codes and mini games, test them and publish the hunt encrypted. Players only unlock the next clue at the right place — and a comic intro, a ranking and a finale with fanfare make it an adventure.
Circle the damaged section, sketch the escape route, measure the distance to the next hydrant. Whatever you mark lands in the workbook as its own object, so several people can draw at the same time without getting in each other's way.
MindooDB stores every change append-only — nothing is overwritten. So Cairn can show a workbook as it was on any earlier date and put it next to today: side by side, or with a slider you drag across the map.

Every device holds the full, encrypted workbook. You work at full speed offline, and changes merge without conflicts once devices are back in touch.
Download map areas ahead of time, or use the offline planet map. Map material and workbooks stay usable in the cellar, in the forest and in the disaster zone.
When there is no server within reach, devices sync directly with each other and carry updates from team to team.
Each pin, stroke and measurement is its own document, so parallel work merges as new objects instead of fighting over one drawing.
Everything is encrypted on the device before it is stored or sent. Even the operator of the sync server only ever sees ciphertext.
Everyone who holds the workbook's key can read it — ideal for a team, a department or an event crew.
Only the people you name can decrypt the workbook. Perfect for sensitive situation maps or private property.

Cairn runs wherever MindooDB Haven runs: on the phone in your pocket, on the tablet in the command vehicle and on the big screen in the office. Thanks to sync, all of them always show the same map.
Cairn is not only for serious work. Plan a city rally for a school class, a birthday or a team event: players follow encrypted clues, solve mini games with camera, microphone and motion sensors and race for the podium.
Players see their trail, the next clue and their team on the map. A balloon-popping mini game is one of many challenges a station can hold.
Switch between classic OpenStreetMap tiles, sharp vector maps and a 3D view with buildings. Tilt and rotate the map with two fingers, and tap any point of interest to see what OpenStreetMap knows about it.
Print the map as a wall-sized poster for the briefing, hand out inspection records as PDF, or send a situation report to the command staff.
Any section of the map, tiled across as many sheets as you like.
Inspection records with photos, tree lists and measure lists.
Incident log, orders and the current situation as PDF.
General map, crisis situation, tree inventory, asset inspection and scavenger hunt.

Cairn is an app for MindooDB Haven, the local-first platform for end-to-end encrypted team apps. Install it from the Haven App Store next to your other apps and share workbooks with the people you already work with.
Data lives on your devices first. The app opens instantly and never waits for a server.
Keys stay with you. Servers store and forward ciphertext only.
Every change is kept, which is what makes time travel possible.
German, English, Spanish, French, Italian, Norwegian, Dutch and Polish.
No. Workbooks are stored on your device, and map areas can be kept offline. You need a connection — or another device nearby — only to exchange changes with your team.
Two devices that can reach each other exchange the changes the other one is missing. Because every object is its own document and MindooDB merges without conflicts, the result is the same no matter in which order devices meet.
Only the people you allow: either everyone who holds the workbook's shared key, or a list of selected users. Data is encrypted on the device, so the sync server cannot read it.
Smartphones, tablets and desktop computers — in the browser and in the Haven apps. You can draw with a pen, with your finger or with the mouse.
Yes. Time travel opens a workbook at any earlier point in time and compares it with another one, side by side or with a slider.
From OpenStreetMap and its contributors, as raster tiles or vector maps. Points of interest can show the OpenStreetMap details behind them.
