What a symptom tracker app should do
A good symptom tracker app is one you will still use on a bad day. That means logging in seconds, keeping symptoms next to meds, mood and sleep, and showing you patterns so the effort pays off.
Heylixir is built around that idea: low effort in, useful patterns out. You can log by voice or tap, and everything lives in one timeline.

Track symptoms, meds and mood together
Symptoms rarely travel alone. Sleep, stress, meds, activity and mood all play a part, and a tracker that only counts symptoms misses the story. In Heylixir you can rate each symptom, log doses and note how you feel, and see them side by side.
Reminders help meds and check-ins stay consistent, and your journal catches the context numbers cannot.

See patterns with Halo AI
Halo AI is built into Heylixir. It looks across your logs and points out patterns, triggers and early signs of flares in plain language, so you do not have to hunt through every entry.
Insights are patterns in your own data, not a diagnosis. They are a concrete starting point for talking with your healthcare provider.
