Your timeline: where you went today, and how you got there.
On-device route detection, passive battery efficiency, and zero telemetry.
Huginn logs where you go and how you get there. It does this without using much battery (~4% per day on an iPhone 17 Pro) and without sending identifiable data anywhere.
You never press record. Your iPhone already notices where you stop and how you move, and Huginn asks it. GPS runs only while you’re moving, and rests when you do.
Huginn learns from your corrections. It notices underground movements (Metro, Tube, U-Bahn), your walking speed, and frequent routes. Correct a place once, and Huginn remembers.
Check into significant places to keep a record of what you cared about. Split a walk to mark a turnaround point or merge two walks with an insignificant stop in between.
Huginn needs nothing else. If you also keep a diary in Muninn, Muninn reads Huginn’s days and shows where you went beside your photos.
I’m a cook who codes at night, essentially the inverse of my coder friends, who cook to relax. Huginn is built to be private within the same strict privacy laws that govern everything in Norway and the EU. Also: if I ever stop maintaining it, its complete source code will be published 30 days later under an open license.
Your timeline is one file on your iPhone. No account, no app servers things get sent to, and no analytics. With iCloud Drive on, each day is secured by Apple’s Privacy Policy and only accessible to you.
To suggest a name for a new place, Huginn asks Apple once. No identifying information is transmitted, beyond what Apple transmits itself. Maps and search tiles come from Apple too.
Odin’s two ravens fly out over the world every day and come back to tell him what they saw. Muninn is memory: it shows this day across your years. Huginn is thought: it goes out, looks, and reports where it has been.
I’m a cook who codes at night. Huginn is the second raven, made to sit beside Muninn, and works just as well without it.
