Hunch turns the offhand notes you already make — what you ate, how you slept, how you felt, how clearly you could think — into a picture of your patterns across sleep, focus, energy and mood. It surfaces the subtle, recurring cues most of us have learned to ignore, and points to small, low-cost things to try. Observations, never diagnoses.
The tools meant to catch illness early — the NHS Health Check screens blood pressure, cholesterol, BMI — only fire once a problem is already measurable. The genuinely early window is pre-clinical and personal: brain fog after certain meals, an afternoon energy crash, a flat mood, sleep that breaks after late screens.
And these aren't nothing. Fatigue is among the first signs of conditions from type 2 diabetes to depression — in one review, 93% of people later diagnosed with depression had an identifiable early symptom first. We dismiss the cue precisely when it matters most, because it's vague, individual, and there's never been a cheap way to connect a cause on Monday to an effect on Tuesday. So it all becomes the same shrug: just tired.
The same late dinner, the same 11pm scroll affects two people differently — the science on personal glucose response and chronotype is clear on this. Population advice can't catch a pattern that only exists in yourdata. That's the gap Hunch is built for.
“Ate late, slept badly, groggy all morning.” Type it or speak it. No forms, no scores.
Your notes become a picture of how actions and outcomes line up across days — sleep, focus, energy and mood — not a single bad night.
“Disrupted sleep on 5 of 7 nights you logged late screens.” A pattern worth noticing — shown with your own dates as the evidence.
Tap to see low-cost things to try, each with a reputable source. Nothing is pushed at you.
Everything is frequency-framed — “X on 5 of 7 days you did Y.” Never “you have,” never “Y causes X.”
Suggestions only appear after you tap to see them. The tool surfaces patterns; it never prescribes.
Every suggestion shows its reputable source — NHS, Mind, Royal College of Psychiatrists. No made-up advice.
A visible reminder, on screen: this surfaces patterns to discuss with a clinician. It is not a diagnostic tool.
The NHS is trying to move upstream — from treating sickness to preventing it. But prevention keeps being framed as population advice, and people keep delaying. Nearly half of us avoid the GP, often hoping a problem will simply pass.
We think the real bottleneck is earlier than that. Before someone decides whether to seek help, they have to notice something is worth attention. And the earliest signs are exactly the ones that are easiest to wave away as “just tired.”
Hunch is a small attempt to give those discarded signals somewhere to go — to make a personal pattern visible enough, and gently enough, that a person can act on it early, cheaply, and on their own terms.
