Daily Symptom & WHOOP Tracker

Log your symptoms, pull in your WHOOP data, compare chemo cycles, and find out whether what you're feeling is normal — or at least normal for you.

I built this because I was sick of not knowing whether Day 3 of chemo was supposed to feel this rough. You're on your third or fourth cycle, and you can't quite remember if the nausea hit harder this time. Or whether your HRV dropped further. So you spend 2am scrolling through hospital notes and WHOOP data, panicking slightly. This tool puts it all in one place.

What It Does

Daily Symptom Logging

Quick, frictionless entry for how you're feeling each day. Energy levels, nausea, pain, sleep quality, appetite — whatever matters to you.

WHOOP Data Integration

Pulls in your sleep, recovery, strain, and HRV data. See your body's objective metrics alongside your subjective feelings.

Historical Cycle Comparison

Line up your last three chemo cycles side-by-side. Compare Day 3 to Day 3. Is it actually worse, or does it just feel worse?

Pattern Recognition

AI spots the patterns you'd miss. When your energy crashes. Whether steroids on Day 1 help or hurt. What's consistent.

Reassurance Engine

At 2am, when your HRV is 15 and you're convinced something's broken, see exactly what your HRV was at the same point last cycle.

NotebookLM Backup

Your complete tracking history is backed up to a NotebookLM library. Ask it questions about your own data over months.

Who It's For

Anyone on active chemo who wants to understand their own patterns. You don't need technical skills. You don't need to know anything about your WHOOP data — the tool does that part.

How to Get It

I'll build a personalised version for your specific chemo schedule, medications, and tracking preferences. You choose what to pay — 50% goes directly to a cancer charity.
