Moodline, a private mood journal with a public pulse

Why it surfaced

Moodline makes privacy and restraint part of the product: entries stay on the device, scores are calculated locally, and the collective view receives only an opted-in colour and hour. Its copy is unusually clear about what it does not promise—no diagnosis, ranking, or simulated empathy—while still giving a hard day one simple button.

A Bulgarian-English mood journal that tracks check-ins, sleep, energy, and reflections locally, with optional anonymous signals shared to a collective view.
