The problem.
Weather apps tell you what it’s doing where you are. Navigation apps tell you how to get there. Neither tells you what you’ll drive into three hours from now.
On a long drive, the forecast that matters isn’t the one for your driveway or your destination. It’s the one for each stretch of road, at the moment you reach it.
What we built.
A native iPhone app that fuses turn-by-turn navigation with the forecast along your whole route, timed to when you’ll actually be there.
Set your destination
Search an address or drop a pin, like any navigation app.
See the weather along the route
Live conditions laid over every mile of the drive, and every hour until you arrive.
Drive ahead of the weather
Pick the best time to leave, take the safer detour, or reroute when conditions change.
Navigate
Turn-by-turn directions with live traffic, so you always have the fastest way through.
Plan
Check conditions hours or days ahead and choose a departure that keeps you out of the weather.
Avoid
Reroute around storms, road work, and slowdowns before they cost you time.
Nationwide forecast
Pan, zoom, and scrub forward in time across the whole country before you leave.

Seven years in production.
Navver has been live since 2019, built and maintained by one engineer through seven years of iOS updates, and it is still being improved.
That is the part most agencies never see: what it takes to keep software working, and worth using, long after launch.
Under the hood.
Native iPhone app
Written in Swift and SwiftUI. Built for iPhone, not ported to it.
Maps and directions
Mapbox for maps, routing, and turn-by-turn navigation.
Route forecasts
Forecasts are matched to each stretch of road at the time you’ll reach it, not just where you are now.
