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.
There are no ads. There is no analytics.
- Three starting templates ("Cover the plants", "Severe weather",
"Outdoor plans") let you go from install to first rule in under a
minute.
**Four trigger types**
- Temperature crossings — above or below any threshold, over a
customizable forecast window.
- Precipitation accumulation — total over the next N hours.
- Wind speed.
- NWS alerts passthrough — tornado warnings, flash flood warnings,
winter storm warnings, etc.
**Severity tiers**
- Standard — sound + vibration.
- Quiet — banner only, no sound.
**Privacy at a glance**
- No accounts, no logins, no ads, no analytics.
- The addresses you watch and the rules you set stay on your phone.
- The only 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).
