Cortisol Calmer turns a steadier day into a short daily checklist and one simple number to watch. Eight small, science-backed habits, the kind linked to a steadier daily stress rhythm, laid out as a quick tick: • Morning light • Consistent bedtime • Screen wind-down • Caffeine cutoff • Breathwork • Light movement • Protein breakfast • Evening magnesium Tick what you did and your Calm Score fills in: a single 0–100 read of how much of your routine you kept that day. It's a guide to your habits, not a medical measurement of your cortisol. SEE IT WORK The Trends dashboard lines every habit up on one timeline with your Calm Score on top, so your steady stretches and your rough ones show at a glance, across two weeks, a month, three months, or all of it. It lines the days up; the pattern is yours to read. BUILT TO STAY SIMPLE • Free, with everything unlocked. • Fully on-device: no account, no sign-up, no sync. Your data never leaves your phone. • No ads, no tracking, no spam. One quiet daily reminder, only if you want it. • A share card to post your progress, whenever you feel like it. Cortisol Calmer is a wellness and habit-tracking app. It does not diagnose, treat, or measure any medical condition, and nothing in it is medical advice. If stress is affecting your health, please talk to a qualified professional.
