Frost: Frost & Freeze Alerts
Warned the evening before
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Frost or freeze tonight? One calm alert the evening before, for your place.
Frost can damage plants overnight. Get an evening heads-up for the night ahead.
Set your place once. Frost keeps checking the forecast for the nights ahead, and if it dips toward frost you get one calm notification at the evening time you choose (6 pm unless you change it) — a prompt to bring potted plants inside, throw frost cloth or an old sheet over anything tender, or cover the windshield for the night.
- One notification, not a feed — one per saved place on each night with forecast frost risk, sent the evening before.
- Frost above freezing — on a clear, calm night frost can form while the air is still above freezing. That is why the app warns before the forecast reaches freezing, and why it says "frost possible" instead of pretending nothing is happening.
- Honest about risk — we say why ("clear and calm — frost forms easily"), not just a number.
- Severity at a glance — * frost likely, ** higher frost risk. Readable on a lock screen at night without your glasses.
- More than one place — the garden, the raised beds, the community plot. Each with its own threshold.
- The nights ahead — see the coming nights and prepare the tomatoes and basil for a late spring frost.
- Fahrenheit, the way you read weather — degrees in °F from the first launch, with °C a single switch away.
- Reliability you can see — a "last checked" indicator, always.
- Private — saved places stay on this device; coordinates are sent to WeatherAPI.com to fetch forecasts. No account, ever.
- Quiet when there is no risk — no routine notification when the available forecast shows no frost risk.
Frost is an estimate from a forecast, not a government product — cross-check anything that matters. Free with a single small banner. One small purchase removes it forever. No subscriptions. No plant database to feed. One job, done properly.
