Know what's open at KM 437.
Your GPS draws a perfect line to the finish. It just doesn't know the only shop on it shut twenty minutes ago. Rekker turns any GPX route into an offline roadbook for resupply, opening hours and water, readable in one glance.
No account · No cloud · No subscription
Full offline data in eight countries — and anywhere else works online via OpenStreetMap.
On a long self-supported ride, the rules are simple: no support crew, no private resupply. Whatever you eat, drink or fix, you find along the way. The ride isn't made on the climbs — it's made at the shop that was actually open.
Your GPS computer is brilliant at one thing: the line. But the line doesn't know that the next shop closes in twenty minutes, that the water tap is 300 metres off route, or that everything in the next 60 km is shut until morning.
So riders improvise: spreadsheets, screenshots, guesswork. Planning that eats evenings and falls apart the moment you're behind schedule.
At hour 21, with a sleep-deprived brain, you shouldn't be doing logistics. Your roadbook should.
Rekker works in two phases with opposite jobs. One uses the internet, once, while you plan. The other never needs it again.
Upload your route. Rekker scans open map data along your exact line and builds the roadbook for you:
Install it once and plan while you have signal. The roadbook then lives on your phone, so you switch to airplane mode and ride. From here it's yours:
Rest stops every ~80 km, plus every supermarket, bakery, fuel station and fast food within the range you set. No detours into the unknown.
Chain opening times per day, with the right local rules — closed Sundays in Germany and the Alps, open Sunday mornings in France. Shops that will be shut when you arrive simply dim out. CLOSED is a fact, not a surprise.
Tens of thousands of public taps across Europe, plus the cemetery taps riders rely on, within a range you choose (300 m by default). Empty bottles stop being a navigation problem.
Not "works with weak signal" — works with no signal. The whole roadbook lives on your phone. Test it in airplane mode before the start, then trust it.
Brevet controls ride straight in from your GPX. Pin a supermarket or a hotel you can't miss, or drop your own point at any kilometre — your stops, on your route.
Big numbers, high contrast, one screen. Designed to be read in under a second at 28 km/h — so your eyes stay on the road, not on a map.
We're prototyping a companion e-ink display for the handlebar: your next stops, food and water on a screen that's readable in full sunlight and sips battery for days. No backlight burning through your power bank at 3 a.m. — just the four numbers you actually need.
It's early. But it points at what Rekker believes: the best kit is the kind you forget is there.
Rekker started as one rider's preparation for the Race around the Netherlands — 1,900 km, self-supported, against the clock. It became a tool because the spreadsheet wasn't good enough — and it turns out brevet riders, bikepackers and weekend tourers need exactly the same thing.
If a feature needs a connection mid-race, it doesn't ship. Coverage maps lie; your roadbook shouldn't.
Powered by OpenStreetMap and public water data. Free data in, fair tool out — and every rider gets the same information, exactly as self-supported riding intends.
We measure success in seconds not spent looking at your phone. The goal is a tool you check, not a feed you watch.
