Questions, answered plainly
What Underweather does, what happens to your information, and the things it deliberately will not do.
What is Underweather?
A private diary for illness. Somewhere to note symptoms, temperature, what you have taken, and the slow turn back toward feeling better — for yourself, a child, or someone you look after. It never tells you what to take. It helps you notice, and remember.
Does my health information leave my phone?
Everything you log is written to storage on your own device. There is no account, no login, and nothing of yours is kept on our side. The one exception is a reading: when you ask for one, that single entry — symptoms, notes, any photos — passes over a secure connection to the AI provider that writes it. It only passes through. We do not keep it, and it is never used to train anything.
Can it tell me what is wrong with me?
No. Underweather is not a diagnostic tool, not a medical opinion, and not a replacement for professional care. It gives a plain summary of the day you logged, in ordinary words, so you can see patterns and describe them accurately to someone who can help.
Will it tell me what to take?
No, and that is deliberate. Anything about medicines — what to take, how much, whether to stop — belongs with your doctor or practitioner or pharmacist. Underweather records what you took and when; it does not advise.
How does it help with a doctor's appointment?
It produces a summary covering the period you choose — when things started, how they changed, what you took and when, and the points you want to raise. You can print it or share it. It is the checklist people are usually told to fill in the night before, except it was already filled in as the days happened.
Can I keep track for my child, or a parent?
Yes. Four people are included, so you can keep a separate record for a child or a parent as well as yourself. Each person's record is their own.
Does it work without an internet connection?
Logging works on the device and needs no connection. A connection is only needed when you ask for a reading, because that is written by an AI provider.
Do I need a subscription?
Yes — Underweather is a subscription, with up to four people included. On the yearly and monthly plans you can upgrade to include up to six people. Creating a record of your own needs an active subscription: the daily notes, the readings, the conversations and the summary you take to an appointment plus more. What you have in your story stays readable if you cancel. You can export a copy at any time. The price is shown in the App Store or on Google Play.
What happens to my record if I stop paying?
You keep read-only access to your own history. Your record does not disappear and is not held hostage — you can still read it, and you can still export a full copy at any time.
Can I get my data out?
Yes, at any time. Export produces a complete copy of everything on the device, which you can keep or move to a new phone yourself.
Are there ads? Is there tracking?
No, and no. Underweather is made independently and is not funded by advertising. Health data is never used for advertising and is never passed to a third party.
Can I lock the app?
Yes. You can set a PIN, and open it with Face ID.
Does it connect to Apple Health or a watch?
It can read from Apple Health on iPhone and Health Connect on Android, if you allow it. That is optional — nothing is read unless you turn it on.
Is it only for colds and short illnesses?
No. It covers a short illness start to finish, an ongoing condition tracked over months and years with flares marked, the period before and after an operation, and everyday things like sleep, energy, mood and blood pressure.
Who makes it?
It is made independently in Adelaide, Australia, by Sweet Lime Productions Pty Ltd. You can reach us at hello@underweather.com.au.
Underweather is not a diagnostic tool and is not a substitute for a doctor or practitioner. If something feels wrong, or is getting worse rather than better, contact your doctor or practitioner or seek care — whatever a record says.
