Mood Symptom Tracker: Meridian

Track how you feel — and find out why. Meridian logs your mood, sleep, energy and symptoms, then surfaces the patterns that connect them.

Meridian helps you understand how you actually feel — and what's driving it.

Most trackers just collect data. Meridian connects it. Log your mood, sleep, energy, and physical symptoms in seconds, and Meridian quietly finds the patterns between them — so you stop guessing and start seeing what really moves your wellbeing.

WHAT YOU CAN TRACK

• Mood — how you feel, day to day, without a 20-question survey. • Sleep & energy — how rested and how charged you are, and how they trend. • Symptoms — headaches, pain, anxiety, stress, whatever you want to keep an eye on. • Your own signals — add the things that matter to you and track them too.

THE PART THAT MAKES IT WORTH IT

• Patterns, not just charts — Meridian surfaces correlations ("your low-energy days tend to follow short sleep") so the data turns into insight. • A real diary — look back over weeks and months and actually see the shape of how you've been. • Gentle, never naggy — a quick daily check-in, not another app demanding your attention.

WHY YOU'LL TRUST IT

• Private by design — your health journal stays on your device. No account, no ads, nothing harvested. • Calm and fast — log in seconds and get on with your day. • Works on iPhone and iPad, portrait or landscape.

WHO IT'S FOR

• Anyone managing anxiety, stress, or low energy who wants to see what helps and what hurts. • People tracking a chronic condition or symptoms who need a clear record to bring to a doctor. • Anyone who journals their mood and wants the patterns pulled out automatically, not by hand. • Quantified-self types who want correlations, not just another logging chore.

Meridian is quiet, private software for noticing yourself — no streaks to perform, no feed, no judgment. Just a calm daily check-in and, over time, a picture of you that's genuinely useful.

Whether you're managing a chronic condition, tracking mental health, or just trying to feel a little more in control, Meridian turns scattered days into a clear, private picture of you. Download it and start noticing the patterns.
