Rain or rinse
RainOrRinse tells you whether to wash now, wait, or just rinse — in two seconds. Built for tropical weather.
Takes 30 seconds. No account. No email. Your data stays on this device.
We use this if you don't grant live location. You can change it anytime.
Tip: this is just a starting point. The app uses live GPS when you grant access — so it works wherever you drive, even across the SG–MY border.
Just tap the icons. We'll save the rest for later.
One quick pick sets your wash frequency, rain tolerance, and how soon to rinse. You can fine-tune any of these later.
Helps us give a useful answer from minute one. Rough is fine — you can adjust later.
A coating changes how long your car can safely go between washes.
Optional — but it's how the app handles you crossing the SG–MY border without missing a beat.
Location is read only at runtime. Never sent to a server.
When you continue, we'll save your setup and open the app.
Open RainOrRinse any time to see whether to wash now — and how many clean days you'd get.
💡 Pro tip: Install RainOrRinse to your home screen for one-tap launches. Tap Share → "Add to Home Screen" on iOS, or the install icon in Chrome on Android.
Pick which forecast provider feeds the engine. Open-Meteo is the global default — accurate, free, and works anywhere. Country-specific providers will activate in Phase 2.
When did this happen? Defaults to now — tap "Edit time" if it was earlier.
