Features
One tap to start the watch
Hang your laundry, tap "Hung out!", and SentakuGuard starts watching the sky for you until you bring it in.
Live Activity on your Lock Screen
The current rain risk stays visible on your Lock Screen and in the Dynamic Island — no need to open the app.
Warned before the rain arrives
SentakuGuard tracks approaching rain clouds and sudden downpours, and alerts you minutes before rain reaches your laundry.
12-hour rain risk at a glance
A simple timeline shows when rain is expected over the next 12 hours, so you can pick the best time to hang and to bring in.
A simple log of every watch
Each "Hung out" to "Brought in" session is recorded, so you can look back on how your laundry days went.
Hung the washing out, then got caught by a sudden shower? SentakuGuard does one thing and does it well: it watches the sky while your washing dries.
HOW IT WORKS
1. Hang out your washing and tap "Hung out!" — the watch begins.
2. SentakuGuard tracks approaching rain with minute-by-minute and hourly forecasts.
3. Bring in your washing and tap "Brought in!" — job done.
ALWAYS IN VIEW — LIVE ACTIVITY
While the watch is running, a Live Activity stays on your Lock Screen and in the Dynamic Island. At a glance you see the current rain risk — Safe, Clouds approaching, Rain soon or Raining — plus a mini bar chart of the rain probability for the next 12 hours. You can even tap "Brought in!" straight from the Lock Screen.
WARNED BEFORE THE FIRST DROP
Get an alert 10, 20 and 30 minutes before rain is due to reach you, and a follow-up the moment it starts to fall. Each alert can be switched on or off.
SMART FORECASTS
SentakuGuard combines minute-by-minute rainfall for the next 60 minutes with hourly forecasts for the next 12 hours. Choose between two sensitivity levels (40% or 25%) to decide how cautious the warnings should be.
NEVER FORGET THE WASHING
Set a bring-in reminder for 2, 4 or 6 hours — or for sunset — so your washing never stays out after dark.
YOUR TRACK RECORD
See your streak of consecutive dry days, the number of watches you have run and how many times you have beaten the rain.
