Lantern - A Mood Tracker

Martine Skorbakk

About this app

Lantern is a mood tracker built around one question: how did the conditions run tonight?

Each day/night, mark your watch — Clear, Settled, Overcast, Squall, or Storm.
No scores. Just an honest record of how things have been.

THE LOGBOOK
A calendar heatmap of your nights. Patterns emerge over time. The record belongs to you.

THE TIDES
See the shape of your recent weeks. Where the weather built, where it eased. A weekly note from the harbormaster drawn from your log.

THE RAVEN
After each entry, a short observation based on what the record shows. Not advice. Just what's there.

PRIVATE BY DESIGN
No account required. All data stored on your device. Nothing shared, nothing tracked. Export your log anytime as plain text.

SECURE
Optional passcode and fingerprint lock.

Free to use. No ads. No manipulation.

Lantern is for people who want to track how they feel without being told how to feel about it.

KEEPER'S EDITION — COMING SOON
A premium tier is in development — expanded palettes, customization, pattern-aware observations, and deeper log tools for
those who want to go further.

Keep the light.
