Commanding confidence rating on RainVoid FutureCast keeping you dry.

Proven on 293,295 simulated rides through real, archived NOAA storms, Oct 2025–Oct 2026 — the testing that tunes RainVoid FutureCast.

When the current FutureCast engine called a ride dry, it stayed dry on 5,350 of 5,403 simulated rides — with the rain tolerance set to Drizzle OK, judged against the radar that actually followed. Results as of October 22, 2026; actual results vary.

RainVoid FutureCast vouches for your road only as far ahead as it is confident of where the rain cells will be; beyond that it says “possible”, from the tracked drift of the cells and a safety margin measured on simulated rides through real, archived storms.

What it does

Eight things a radar map can't.

A real storm near Tunica, Mississippi on the plan picture: the direct road runs into a heavy cell, the way around is drawn in blue and the radar that followed kept it dry

Our own storm engine, proven on real storms.

RainVoid Futurecast tracks every cell from the radar itself and projects it to the minute you arrive — direction and speed named on your plan. Where it will be, not where it was.

Guidance with the rain strip and the Weather changed card: Nearest cover, Dry route and Turn back

It rides with you, and re-plans when the sky moves.

Every new radar frame re-scores the road ahead. Nearest cover, a dry route, or turn back — one card, your call.

The rain plan rows: Ride around it, Ride + shelter, Wait it out

Ride around it. Ride + shelter. Wait it out. And the best call.

Three ways around the rain, each priced in minutes — and a gold ★ BEST CALL on the one RainVoid would take, with the reason: judged by the minutes each costs and by what would happen to riders on roads like yours.

The awareness compass over Memphis: red cells with drift arrows and the nearest town named under each

Every cell around you, and which way it's going. Or spin the wheel.

The compass scans every direction and names the nearest town under each cell. Bored? Roulette picks a restaurant or attraction you haven't been to, within the hour.

The stops fan over the dock: Coffee, Food, Ice cream, Cover+, Raining?

Fuel in one tap. Coffee, food and ice cream on the way.

One tap plans the nearest station. The stops fan finds you a dry ride to the next coffee, meal or cone.

The idle screen over a live storm in southeast Idaho: the Work and Home chips under the search card, both reading rain on the road, no dry departure in the reach yet

Your commute, at a glance. And the ride home, watched.

Save Home and Work once. Two chips under the search card carry the call on every radar generation: dry · 47 min, or leave in ~20 min to stay dry, or leave by 8:10 to stay dry. A home-screen widget shows the same scan, refreshed every 15 minutes. When you arrive, say when you are heading back and to where. Watch it, and RainVoid arms the same watch that Wait it out uses on the road back: a heads-up so you have time to get going, the all-clear when the whole road is dry, a notice if it changes.

An example ride receipt: the direct road 10 min of heavy rain from minute 41, your road 0 min of rain and 22 min longer, and the story of the two reroutes

A receipt for every ride. A season you can share.

When RainVoid rerouted you or held you at the door, the arrival card becomes a receipt: what the direct road would have given you, measured on the radar at the minutes you would have been there, beside what you actually rode. Your season adds it up: rides watched, rides kept dry, wet minutes avoided, the biggest save. Share either as a picture; your location never leaves the phone. Shown: an example receipt.

Rate a stop, add the overhang you sheltered under, confirm each other's. The verified ones feed everyone's shelter plans.

A real storm near Tunica, Mississippi: the direct road runs into a heavy cell, the way around is drawn in blue and the radar that followed kept it dry
01 · RainVoid Futurecast

Our own storm engine, proven on real storms.

Every cell tracked from the radar itself and projected to the minute you arrive, forecast only inside a high-confidence window proven against real storms. The cells that matter are named with their direction and speed. When the direct road runs through one, the way around is drawn on the picture and priced in minutes.

02 · The rain plan

Ride around it. Ride + shelter. Wait it out.

Three ways around the rain, each priced in minutes — a covered stop you reach before it, a dry way around it, or the minute the road clears with a notification when it does. The gold ★ BEST CALL marks the one RainVoid would take, and its line says why: the minutes each costs, and what would happen to riders on roads like yours.

03 · Your rules

Your rain. Your detour. Your margin. Your load.

Four chips decide what counts as rain for you. The app still says what's on the road, even when it's within your settings.

Rain toleranceThe wettest you'll ride in: dry only, drizzle OK or light rain OK. Anything heavier is rain and gets routed around.
Max detourHow many extra minutes a dry road may cost before RainVoid stops choosing it for you and only offers it.
Safety marginNormal keeps your road at least the forecast’s own position error from painted rain — about 1 mile at 5 minutes out, 4 miles at 20 — warns of rain ahead 10 minutes out, and needs a covered stop 5 minutes before the rain. Cautious widens that buffer by half (about 2 miles at 5 minutes out, 6 at 20) and warns 15 minutes out. The same buffer runs past Futurecast’s reach, up to about 12 miles an hour out.
Cargo modeHauling something that must stay dry? Locks tolerance to dry only and the margin to Cautious, and prefers covered stops.
Guidance over Nashville: the map and the green bar Detouring around the rain, +17 min, with Keep my road and Got it
04 · Or let it decide

Rain pops up. It takes the dry road. You keep riding.

Sometimes a storm moves faster than radar can predict, and rain shows up on your road mid-ride. When that happens and a dry road fits your detour limit, RainVoid switches you to it, tells you out loud, and shows a green bar with the extra minutes. Tap Keep my road to go back to your original road. Tap Got it to accept the detour. It is on from your first ride. If no dry road exists, the Weather changed card offers the nearest cover, a dry route when one appears, or a turn back. Prefer to decide every time yourself? One switch in Settings turns it off.

From the builder

Pilots don't guess at weather.

RainVoid was built by a mechanical engineer and military pilot who got tired of guessing at the sky from a motorcycle seat. Pilots read the radar, time the cells and pick their window. RainVoid brings that discipline to the road.
