Onni — Symptom Tracker

Quickly note down a symptom, a medicine taken for relief, or a reading of your vitals — for you or your family — and keep a history for your doctor or for AI analysis.

Onni is a simple, private way to record how you or your family are feeling — built for the off-days, not for daily baseline tracking.

When someone isn't well, open Onni and log it in seconds: a sudden headache, a fever, stomach pain, or the paracetamol you gave your child. Add how severe it is, when it happened, an optional note, and even a photo of a rash or swelling. Later, see a clear history and simple charts, and export a tidy PDF or spreadsheet to share with your GP.

WHAT YOU CAN RECORD • Symptoms — choose from common ones or your own, with severity, timing, an optional duration, a note, and a photo • Medications — over-the-counter relief, with dose and timing • Vital signs — temperature, blood pressure, blood sugar, oxygen, pulse and breathing rate

REMINDERS • Set once, daily, or weekly reminders to take a medication, re-check a symptom, or record a vital again • Tap a reminder to record straight away, pre-filled and ready

BUILT FOR FAMILIES • Keep separate records for each family member, each with their own colour • Switch person with a single tap

LOOK BACK & SHARE • Browse your history, search it, and view trends over time • Export a clean A4 PDF (with charts and photos) or a CSV spreadsheet • Send it by email, Messages or WhatsApp for a GP appointment

PRIVATE BY DESIGN • Everything is stored only on your device • No account, no analytics, no advertising, nothing sent to us or anyone else
