Check in without judgment
Pick a mood, add a note if you want, and move on. The log builds a pattern you can review over time.
Guided 4-7-8 breathing
Inhale 4s, hold 7s, exhale 8s — an evidence-based pattern that activates the parasympathetic nervous system.
Regulation when you need it
Quick ideas for grounding: cold water, 5-4-3-2-1, bilateral movement, slow exhales.
Common questions
Is this a medical device?
No. Daybook is a wellbeing tool, not a medical or therapeutic device. Seek professional help for clinical concerns.
Is my mood data private?
Yes — stored locally only. No server, no tracking.
How long is a breathing cycle?
One full 4-7-8 cycle is 19 seconds. Repeat 3–5 cycles when you need to settle.
