RitualOS

Science-backed habits, run by an AI that knows your body clock.
Habit apps tend to fail in one of two ways: generic reminders nobody follows, or so much manual logging that the app becomes another chore. RitualOS was built around a different premise — let an AI actually plan the day, timed to the user's own body clock, and keep every habit graded by how strong the evidence behind it really is.
Aura, the app's AI layer, turns a plain-language goal into a full circadian protocol in seconds — morning light, caffeine cutoffs, deep-work blocks, wind-down — and re-times it automatically as the user's schedule and data change. Every ritual is tagged with its evidence strength, so the app never asks for blind trust.
We designed the tracking loop to take one tap, not a form: mood, energy, and completion feed a running streak and a weekly lab report that turns a week of taps into one clear, personal read on what's working.
Outcome
Live on iOS and Android with a free 7-day trial — built end to end by Nordfeld Labs, from the circadian protocol logic through the App Store launch.
