Help with Sniffle, the pollen and allergy forecast app.
Where does the pollen data come from?
Pollen levels come from Google's Pollen API, updated about once a day for areas roughly 20 km (12 miles) across. Rain comes from Apple Weather. Hourly timing is estimated from typical daily pollen patterns and the rain forecast.
The level shows tomorrow's forecast in the evening
Pollen forecasts roll over to the next day at midnight UTC, which is the afternoon or evening in the Americas. Sniffle keeps showing today's forecast until your local midnight whenever it can. If an area hasn't been looked up yet that day, you may briefly see tomorrow first; the app says so when that happens.
Location
Sniffle works without location access: tap the city name at the top and search for a place. To use your current location, turn on Location for Sniffle in Settings › Privacy & Security › Location Services.
Morning alerts don't arrive
Check that notifications are on for Sniffle in Settings › Notifications, and that the alert is turned on in the app (the bell at the top). Alerts are only sent on days that reach the level you chose.
Pro and subscriptions
- Restore Pro on a new device: open Go Pro in the app and tap Restore.
- Cancel or change your plan: Manage subscriptions, or Settings › [your name] › Subscriptions.
- Refunds are handled by Apple: reportaproblem.apple.com.
Apple Watch
The watch shows today's pollen for everyone. Pro adds what's in the air, the next days, the daily check-in and the watch face complication. Open Sniffle on your iPhone once so the watch knows your city; after that, the watch keeps itself up to date. For a quick way in on any watch face, add the Sniffle shortcut when you edit the face.
Not medical advice
Sniffle gives general information. Talk to a doctor about your allergies and medication.
