Pollen forecasts, made personal.
Achoo is a calm hay-fever companion. It turns local pollen, a private symptom diary and weekly patterns into one daily brief — tailored to your sensitivities, not the national average.
Achoo is the one product in the Yara Labs portfolio that keeps a dedicated marketing site — it predates the Product Hub model. This page introduces Achoo and routes you to achooapp.co.uk for the full product experience, download links and support.
A few quiet rituals, not a stream of data.
A single number you can actually plan around.
One score for your area, broken into the pollens you're sensitive to, with an honest band — low, moderate, high or severe — and a daily brief that turns the number into a plan.
- Localised pollen score — tree, grass and weed, with the dominant pollen flagged.
- Honest banding — low, moderate, high and severe; no inflated colour signals.
- Today's brief — practical guidance like "take your antihistamine early."
Practical tips, tailored to your sensitivities.
The brief reads the day's forecast against what you've logged in the diary, then pulls together a short list of behaviours — sunglasses, antihistamine timing, washing pollen off clothes — that actually move the dial.
- Personalised to your triggers — the brief weights against your highest-sensitivity pollens.
- In-season notice — Achoo+ shows which pollens are active locally right now.
- Pattern alerts — "Tree pollen is your trigger, based on 7 diary entries."
Plan around the pollen peaks.
Five days ahead, at a glance. The forecast surfaces when the peaks land so you can move runs, plans and antihistamine timing around them — without doom-scrolling a weather app.
- 5-day forecast — colour-coded bands per day, score per pollen type.
- Weekly summary — "Moderate levels throughout the week — stay on top of your antihistamines."
- Tap-to-detail — each day expands into a full breakdown with practical guidance.
A simple, private hay fever diary.
One tap to log how today feels, with optional tags for the specific symptoms. Over a few weeks, that turns into a real picture of which pollens actually trigger you — and which ones don't.
- Monthly calendar heatmap — mild, low, high, severe; instantly readable.
- Symptom tags — runny nose, congestion, itchy eyes, brain fog, more.
- Recent entries — short notes per day; everything stays on-device.
Discover what triggers you most.
Achoo connects your diary to the forecast and surfaces the pattern: which pollen actually makes you feel worse, and on which days. The insight gets sharper every entry you make.
- "Your main trigger" — learned from your diary, not assumed.
- Confidence over time — more entries = more confident insight.
- Calm presentation — green for low days, amber only when it matters.
