Frost kills overnight. We warn you the evening before.
Set your place once. Every evening Frost checks the night ahead, and if the forecast dips toward frost you get one calm notification around 6 pm — in time to cover sensitive plants, move the pots, throw a sheet over the seedlings, or park the car under cover.
- Made for Australia — Canberra, Tassie, the inland, the hills. May to September.
- Honest about risk — clear, still nights form frost above 2°; we say why ("clear and still — frost forms easily"), not just a number.
- Severity at a glance — ✻ frost likely, ✻✻ heavy frost. Readable on a lock screen at night without your glasses.
- More than one place — home, the garden, Mum's. Each with its own threshold.
- The nights ahead — the coming nights at a glance, so a cold snap never surprises you.
- Reliability you can see — a "last checked" indicator, always.
- Private — your locations never leave the device. No account, ever.
