Jacket: Personalized Weather

A forecast that learns you. Rate what Jacket flags and it retunes your thresholds on your phone. New: one morning brief each day with what to wear – no alert spam.

Jacket is a weather app that adapts to how you actually feel – not to what the thermometer says.

Two people standing in the same cold wind don't need the same advice. Jacket starts by asking a few quick questions about how you experience cold, heat, and rain. Then it keeps learning: once a flagged event has passed, give it a thumbs up or down, and Jacket retunes the thresholds behind what it flags. It tells you exactly what changed, in plain English – "Going forward, we'll be slightly less sensitive about rain."

What you get:

• Tuned to you: rain, cold, wind and heat get flagged at your personal thresholds, not generic ones.
• An event timeline: see the rain, snow, wind and cold coming today and tomorrow at a glance, instead of decoding hourly forecast tables.
• Plain-English summaries: one line at the top telling you what to wear or bring today – and what tomorrow needs.
• One morning brief: a single notification each morning with what to wear today. No alert spam.
• Widgets: your summary and the day's flagged events on your Home Screen, without opening the app.
• Learning you can see: every time Jacket retunes itself, it tells you what it changed.
• Learning that stays on your phone: the tuning runs entirely on your device. No account, no ads, no tracking.

How it works:

1. Set your location, or let Jacket find it.
2. Answer a few quick questions about how you experience weather.
3. Check the forecast each morning to see what's ahead.
4. Rate events once they've passed. Jacket does the rest.
