A private way to notice perimenopause and menopause symptoms (hot flushes, sleep, mood, and what you’re taking) with a clear summary for when you see your GP or health practitioner. Nothing to fail at.

Four small parts, each doing a little — never asking you to keep up, keep streaks, or keep score.
A few soft notes a day on how you're feeling — warmth, sleep, mood, energy. No streaks, no scores, nothing to keep up with.
Whenever you ask, Threshold tells you what has been showing up, and what shifted after something new. Never a diagnosis, and always yours to question.
Everything you've noted, gathered into a story you can look back through — and the things worth keeping close.
A clear summary to bring to an appointment, so the things that matter aren't forgotten in the room.

The more you write, the more it has to tell you. A record that isn't just kept, but grows.
Threshold asks for very little and keeps all of it. A note when the day is done, a moment when something happens, and — when you need it — one clear page to take with you.

How the day felt, whether the flushes came, how you slept. It takes a moment, at whatever hour suits you — and skip any of them. A note, not a test.
Step one
A hot flush at 3am, a headache before lunch, a walk that helped. Say what it was and how strong it felt — dated and exact, without writing an essay.
Step two
Months of small notes become a clear summary. Choose what goes on it and how far back it reaches, then print it, send it ahead, or just hand over your phone.
Step threeThreshold holds the appointment together — before it, and after.
The summary carries as much or as little as you choose — your points to discuss, day by day, the nights from your watch, blood pressure, bleeds, what you’ve tried, and what you’re taking now.
If you wear a watch, it already records the things that are hardest to recall in the morning. Threshold reads them, so they sit alongside what you've noticed yourself.
How long, and how broken. A watch sees the wake-ups you slept through — the ones a night sweat leaves behind and the morning forgets.
The overnight shifts, measured against your own usual night rather than anybody else's — the thing you can't feel in the morning.
A background line that moves with the rest of it. Not a score, not a target, just another thing you didn't have to write down.
Apple Watch, Fitbit, Garmin, Oura — they all write into Apple Health or Health Connect already. Threshold reads from there, on your phone. Nothing new to wear.
Threshold only ever reads — it never writes anything back to Apple Health or Health Connect, and what it reads stays on your phone with everything else.
No account needed to begin. Your notes are kept on your phone. A reading sends what it needs, securely, only when you ask. If you ever want a private backup, it's yours to switch on. It is never on by default, and never shared.

Threshold is not a diagnostic tool, and not a substitute for a doctor or practitioner. It helps you notice and remember, and it keeps the record for whoever you choose to show it to.
What is worth noticing through the change, and what to take to an appointment.

Read →I found the app really easy to use and navigate. It had a lovely, calm feel to it, and everything was simple to find without being overwhelming. I also liked that it felt supportive and informative.
This easy to use app is so great! It helps to log and keep track of all my symptoms day to day and weekly and helps to manage things a little better 😊
