Why Kairo exists
At my heaviest I was over 280 pounds. Zepbound helped me get to 209.
Along the way I wanted one place for the details of a routine that kept changing, and a clearer picture to bring to each appointment. That's Kairo.

Your GLP-1 journey
Your first month: build a useful record
You do not need a perfect journal. Start with a few details you can keep recording, then take the questions they raise to your care team.
Read the guideSide effectsReview symptoms by week, without a script
Your log should reflect your experience. There is no week-by-week symptom schedule everyone must follow.
Read the guideYour GLP-1 journeyWhat an estimated medication curve can tell you
A curve is a model built from recorded doses and assumptions. It is not a blood test.
Read the guideTracking & switchingA GLP-1 log that stays with your routine
A good record answers a small set of questions: what did I take, when did I take it, and what did I notice afterward?

Brand name, ingredient, formulation, and prescribed purpose all matter. Use the exact name on your prescription in your log.
Read the guideSide effectsNausea: what to record and what to ask
If nausea is interrupting your day, a short record can help you describe it accurately. Recording symptoms is not a substitute for getting help.
Read the guideSide effectsPut appetite changes into your own words
People use “food noise” to describe recurring thoughts about food. For your record, a concrete example is often more useful than the label alone.

The safe next step depends on the medicine, its formulation, and how long it has been. A calendar reminder is not a catch-up dosing instruction.

Moving to Kairo should not mean changing the date your journey began. Keep a copy of your original export before importing.

Is Kairo free?

Can I bring my history from another app?
Yes. Kairo imports CSV files from other dose trackers and spreadsheets. If a file gives you trouble, visit our support page.
How does the free trial work?

Is Kairo on Android?
No, Kairo is iPhone only for now.
Does Kairo give medical advice?
No. Kairo keeps your records and explains the research. Its charts are estimates, and AI answers can be wrong. Your clinician makes the calls about your treatment.
Your next dose is a good place to start.
