Samukunai: Personal Weather
Learns your comfort zone daily
Only for iPhone
Free · Designed for iPhone. Not verified for macOS.
iPhone
Snap today's outfit and look back at what you wore on similar-temperature days. Plus a weather app that learns whether YOU run warm or cold. Free, no ads.
"Is it cold today?" Get the answer tailored just for you.
The same 15°C feels freezing to one person and pleasant to another. Generic weather apps tell everyone the same thing. Samukunai learns YOUR personal comfort zone from how you actually feel.
■ Morning Notification
At your chosen wake-up time, a notification shows today's weather, how it will feel to you, and what to wear. Open the app and it also reads the brief aloud.
"Today's apparent temperature is 18°. For you, that's cool. Long sleeves with a light layer recommended."
■ One-Tap Feeling Log
Tap a time slot card (morning, noon, evening, night) and pick one of seven levels: freezing, very cold, cool, comfortable, warm, hot, scorching. A few seconds a day is all it takes.
■ Personal Comfort Zone
After 10 records, Samukunai starts using your personal thresholds. See whether you run warmer or cooler than average, and watch your zone refine as you log more.
■ Proactive Day-Ahead Notifications
Get a heads-up 30 minutes before the weather crosses into your "too hot" or "too cold" zone. Five sensitivity levels, can be turned off.
■ 4-Slot Timeline
Morning, noon, evening, and night cards give you today and tomorrow at a glance. Rain, snow, and thunderstorm conditions are chipped on each card. Outfit illustrations and short labels ("layer up", "short sleeves") make dressing quick.
■ Siri Shortcut
"Hey Siri, log with Samukunai" records your current feeling instantly — gloves on, hands busy, doesn't matter.
■ Outfit Photo Log (NEW in v1.0.3)
Snap or pick today's outfit and save it alongside the current temperature. Browse a gallery grouped by temperature to see what you wore on similar days — handy for "I never know what to wear at 18°C" mornings, especially during seasonal transitions.
Photos stay on your device only. They are not synced to iCloud, sent to any server, or included in iCloud backups. GPS/EXIF data is stripped during save.
■ iCloud Sync (feeling logs only)
Your feeling logs sync across your devices via iCloud private database. Outfit photos are not synced and remain on the original device. No one else — including the developer — can access them.
■ Privacy
Location is used only for weather fetch, never sent to external servers. Outfit photos stay on your device. No ads, no tracking identifiers, no in-app purchases.
Free forever. Because your comfort is unique to you.
