## What is Fon?

Will it rain on you in the next hour? Fon tells you when rain will reach where you are in Thailand, how heavy it will be, and when it should ease off.

THE NEXT HOUR, IN 5-MINUTE STEPS
• A plain answer, like "Heavy rain in 12 min" or "No rain for the next hour".
• A 60-minute timeline in 5-minute steps with clock times, coloured from light to very heavy rain.
• Fon says when rain is only possible, not certain yet.

LIVE RADAR MAP
• The past 2 hours of radar and the next hour of forecast. Play it or scrub frame by frame.
• Tap anywhere to see how hard it's raining there and which radar saw it.

RAIN ALERTS
• One alert per rain event, a few minutes before it starts: leave now, call a ride, or wait it out.
• Per place: how far ahead (10 to 30 min), the lightest rain worth an alert, and quiet hours.
• Use your location, or add places by search or by dropping a pin. Location is optional.

HONEST WHEN DATA IS MISSING
If the radar is late or doesn't reach a place, Fon says so. It never shows "no rain" when it can't see.

FON PLUS
Free: the forecast, the radar map, one saved place and rain alerts for one place. Fon Plus adds:
• Rain alerts for up to 10 places
• Lock Screen and Home Screen widgets
• A Live Activity countdown on your Lock Screen and Dynamic Island
Fon Plus is an optional auto-renewing subscription, monthly or yearly, charged to your Apple Account. It renews unless cancelled at least 24 hours before the period ends; manage it in your Apple Account settings.

PRIVACY
No account, no ads, no tracking. Fon keeps only your latest location rounded to about 100 m, the places you save, and a random device ID for your alerts.

DATA
Radar from the Thai Meteorological Department (TMD), TMD's national composite and the Department of Royal Rainmaking and Agricultural Aviation (DRRAA). Forecasts are Fon's own extrapolation, not official warnings; showers that form out of nowhere can't be predicted this way.

In English and Thai.

## Version history (last 3 releases)

### 1.2 — 2026-11-05

Fixes the upgrade screen: prices no longer appear in the wrong currency while the App Store loads.

### 1.1 — 2026-11-04

Fon Plus: rain alerts for up to 10 places, Lock Screen and Home Screen widgets, and a Live Activity countdown.
More radar: the Department of Royal Rainmaking's radars now cover Chiang Mai, the north-east and the deep south, and update every six minutes. Phitsanulok's radar now covers the lower north.
More accurate rain: how hard it's raining is now set against Thailand's rain gauges, and the map shades each strength of rain more finely.
A better next-hour forecast, and the map now runs under the tab bar.

### 1.0 — 2026-11-02

No release notes.
