How it works
Three things, done simply.
Built for your hardest days: short steps, plain words, and nothing you have to remember exactly. Rough answers like "about a week ago" are fine.
01
Log what you feel, and where
Tap the spot on a body map and pick from a short list in everyday words. Note when it started and whether it's still going.
02
See if others reported it
See how many reports of the same symptom have come from people on the same medicines — here in I Feel You and in the FDA's public reports.
Counts only appear once enough people have reported, so no one can be singled out. They show what others reported, not how urgent it is or what it means for you.
03
Bring it to your care team
Download a one-page summary of your own symptoms and treatment — what's ongoing, what's resolved, and when.

Questions
How reliable are these counts?
Counts of what others reported — not a rate, a cause, or a prediction. A count means other people on the same medicines reported that symptom, here or in the FDA's public reports. It does not say the medicine caused it, or what will happen to you. The counts don't say how urgent it is. They show what others reported, so you can decide whether to call your care team. Your care team is the only one who can tell you what it means for you.
What happens to my data if the app shuts down?
You can delete your account and all your data from Settings, whenever you want. We never sell your health data. If the app ever shuts down, we delete what you logged. We don't sell it, and we don't pass it to another company.
Is it really anonymous?
Your email is only used to sign you in. It's never shown to anyone or attached to what you log. There are no usernames, photos, or messages. If you choose to share an entry, only an anonymous count is added. Counts appear only when enough people have reported, so no one can be singled out.
Do I need to install anything?
No, it works in your browser, and we'll email you a 6-digit code. There is no password, and there is nothing to install.
Is it free?
Yes, there is nothing to pay, and there are no paid features. All you need is an email address.
Who is it for?
Patients in cancer treatment, and the people caring for them. It isn't for emergencies, and it doesn't replace your care team.
