Your top is off. Your car is across town.
Top Down watches the exact spot where you parked and warns you when rain is heading for it — with 15 to 45 minutes to get back and put the top on.
For iPhone. Coming to the App Store. No account, no tracking, nothing running on your phone.
Top Down
Rain likely in ~35 min
Light rain is forecast to reach where you parked.
The whole app, in one afternoon
You took the top off this morning. Now the car is sitting three miles away — outside the office, at the trailhead, wherever you ended up. The sky where you are is clear, and you have no particular reason to think about the weather.
Your phone buzzes: Rain likely in ~35 min.
You walk back and put the top on before it starts. That is the entire product. There is nothing to check, nothing to watch, and nothing to remember.
How it works
01Flip the switch when you park
Top Down takes your vehicle's position once, right then, and stops. If you turned it on somewhere else, end the session and start it again at the car.
02Put your phone away
Nothing keeps running. No background location, no polling loop, no app left open. The watching happens on our servers, so the app costs you no battery while it works.
03Go back when we tell you
When rain is forecast to reach your spot inside your warning window, you get a notification. If it closes in, you get a second one.
Who it is for
Anyone who leaves a vehicle open to the sky and then walks away from it.
- Soft top off
- Doors off
- Convertible down
- Targa or T-tops out
- Hardtop in the garage
- Sunroof left open
- Side-by-side
The forecast that matters is the one for where the vehicle is parked, not where you are. That is the whole reason this is a separate app from the weather app you already have.
What it does not do
Top Down gives you a heads-up. It cannot give you a guarantee, and it is worth knowing exactly where the edges are before you rely on it.
- It watches the pin, not the vehicle.
- Top Down has no way to sense where your car actually is. It monitors the coordinates you gave it. Start a session while you are somewhere else and you will be watching the wrong place.
- Sessions end.
- You choose how long, up to 24 hours. When a session ends, monitoring stops — whether or not the top is back on.
- Forecasts are wrong sometimes.
- Rain arrives early, stalls out, or misses you entirely. Alerts can also be delayed or lost: phone off, no signal, notifications switched off, or an outage somewhere between us and you.
- Precise timing is not available everywhere.
- Minute-level rain timing covers the United States, United Kingdom, Ireland, Japan and Australia. Elsewhere Top Down falls back to coarser data, and warnings there are rougher and arrive with less notice. The app tells you when you are in that case.
Treat it as a nudge to go check — not a reason to stop looking at the sky.
What it knows about you
No account
No signup, no name, no email address. Your data is attached to an opaque identifier for your app installation and nothing else.
One location, once
Your position is captured at the moment you flip the switch. The app asks only for “While Using” location and never for background access, so it cannot follow you.
The forecast is fuzzed
Your coordinates are rounded to a roughly 5 km grid square, and the forecast is requested for the centre of that square — so the weather provider never receives where you actually parked.
Ended sessions and their alerts are deleted after 30 days by a scheduled job, not by policy alone. The full detail is in the privacy policy.
