Keep a clearer record
between cancer
appointments.
Symptom Keep™ gives patients and caregivers a clear, private record of symptoms and changes — so you can fight with facts, not guesswork.
Free during Early Access.
Choose one place to keep your record. Your symptom history does not currently sync between the iPhone, Android, and web versions.
Help shape Symptom Keep. Try it and use the in-app feedback feature to tell us what helped and what got in the way.
Symptom Keep is a record-keeping tool. It does not provide medical advice or diagnosis, and your entries are not monitored by a care team.
The Real Problem
Cancer forces you to track everything — pain, fatigue, side effects. But nobody gives you a tool built specifically for tracking and assessing your symptoms with clarity.
Not a wellness app
Not a “patient portal”
Not a spreadsheet
Not a prescription list
Not an appointment tracker
Not a nutrition planner
Not a vitals monitor
Not an all-in-one tool
And definitely not a system that ships your data off to a company you never agreed to trust. People battling cancer deserve better. This is that better.
What Makes
Symptom Keep Different
We’re the symptom tracker built on a simple promise: your symptom entries stay encrypted in your browser and under your control.
Your record is yours to use for your care, no one else’s. This isn’t wellness. This is survival.
No automatic cloud sync of symptom entries.
No ads masquerading as “insights.”
No selling of your symptom history. Ever.
No sharing unless you choose it.
No vague promises about where your information lives.
Why We Exist
Because patients shouldn’t have to fight blind.
Your symptoms.
When your doctor asks, “When did this start?” you deserve to have a real answer — not guesswork under stress.
Your intuition.
When something changes, you are the best person to see it before it spirals out of control.
Your superpower.
When you’re scared, data should make you stronger, not more overwhelmed. Easy to read charts help you see.

Symptom Keep is a responsive web app for recording symptoms and reviewing how they change over time. It creates a clear history you can reference or share with your care team.
Regular entries can make symptoms easier to recall, compare, and discuss during appointments. Symptom Keep organizes what you record without diagnosing symptoms or recommending treatment.
Symptom Keep is free during Early Access. Future pricing and premium features are still being explored.
Symptom entries are encrypted and stored in the browser you use—not automatically synced across devices. Account and profile information is stored separately for sign-in and profile features. You choose when to share a report.
After my own cancer diagnosis, I experienced firsthand how difficult it can be to remember and organize every symptom. I wanted a quick, simple way to create a record I could trust.
Symptom Keep currently works in a web browser on mobile and desktop and can be added to a phone’s home screen. Dedicated native apps may be considered later based on what we learn from Early Access.
