Almanac Bell

Development on Almanac Bell has ended. The app keeps working as it is, but it will not receive updates or fixes. For weather alerts going forward, please install Just My Weather, our replacement app: https://play.google.com/store/apps/details?id=io.raylytics.justmyweather

Almanac Bell is a free, US-only weather alert app for people who just want to know when to bring the plants in.

Set a rule once — for example, "notify me when temperature drops below 40°F at Home" — and the app keeps watch against the US National Weather Service forecast. When the threshold is crossed, you get a local notification with a clear, plain-spoken message: "Frost expected at Home around 6 a.m. Cover the plants tonight."

WHY ALMANAC BELL

• Built for gardeners, parents, hikers, and anyone planning around the weather a day or two ahead.
• The app evaluates rules on your phone. There is no cloud account and no developer-run analytics. The free tier is supported by a single banner ad on the Home and History screens; a one-time Remove Ads purchase clears them forever.
• Three starting templates ("Cover the plants", "Severe weather", "Outdoor plans") let you go from install to first rule in under a minute.

FIVE TRIGGER TYPES

• Temperature crossings — above or below any threshold, over a customizable forecast window.
• Precipitation accumulation — total over the next N hours.
• Wind speed.
• Barometric pressure — alert above or below a sea-level pressure (inHg) you set; a useful early signal that weather is changing.
• NWS alerts passthrough — tornado warnings, flash flood warnings, winter storm warnings, and the rest of the CAP catalog.

SEVERITY TIERS

• Standard — sound + vibration.
• Quiet — banner only, no sound.

PRIVACY AT A GLANCE

• No accounts, no logins, no developer-run analytics, no tracking by us. The free tier shows a banner ad via Google AdMob; AdMob may use your Android Advertising ID for non-personalized ad serving (see the privacy policy for the opt-out).
• The addresses you watch and the rules you set stay on your phone.
• The only first-party data that leaves your device is the latitude/longitude of the places you save — sent to the US Census Geocoder (to resolve your typed address) and to the US National Weather Service (to fetch the forecast).
