Summer storm season is here. Hang out your laundry, tap once, and SentakuGuard watches the sky — rain alerts on your Lock Screen before the first drop falls.
Live radar tracks storms ahead
Hang your laundry, tap one button, and let SentakuGuard stand watch.
It keeps an eye on approaching rain clouds and sudden downpours, shows
the risk right on your Lock Screen and Dynamic Island as a Live Activity,
and warns you before the rain reaches your laundry — so you can bring
it in dry. One purpose, done well: from "Hung out" to "Brought in".
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.
Where does the weather data come from?
Rain forecasts come from Apple Weather (WeatherKit), using your device's location. Forecast accuracy and coverage depend on your region.
Why don't I see the Live Activity on my Lock Screen?
Make sure Live Activities are enabled in Settings > SentakuGuard, and start a watch with the "Hung out!" button. The Dynamic Island is available on supported iPhone models.
Does the app work in the background?
Yes. While a watch is active, SentakuGuard updates the rain risk periodically and sends an alert when rain is approaching. Keeping notifications enabled is recommended.
Is my location sent anywhere?
Your location is used only on your device to fetch the weather for your area. It is never stored on our servers or shared with anyone.
