I built an offline roadbook app for long-distance rides. Looking for testers.
This spring I cycled the Race around the Netherlands and various brevets and kept hitting the same wall during these events: my garmin draws a line to the finish but it gives no clues that the next water is 300 m off route or that a specific resupply spot ahead is closed until morning. I was doing all of that in spreadsheets and small paper roadbooks on my frame and it fell apart the moment I was behind schedule. I also get distracted by opening and searching Google Maps during cycling.
So I built a small app to solve my issues and it worked well during my last 400 km brevet. Now I'd love a few riders to test it.
What it does: you upload your GPX and it builds an offline roadbook containing resupply (supermarkets, fuel, bakeries, fast food), drinking water (and cemetery taps, a 'secret' feature), with opening hours at the time you'll actually arrive - based on avg speed.
You favourite the stops you'll plan to use for a quick view on your goals. And, it also works as a dynamic race planner.
It's a web app you can install to your home screen, then it works fully offline (with GPS or manual km input) after generating a route/roadbook, no signal needed. Built on OpenStreetMap and open water data. Coverage right now in Europe: NL, BE, LU, FR, DE, IT, CH, AT.
It's a beta and I'm a solo builder, so honest feedback is exactly what I want, especially anything that's confusing, slow, or broken on your phone.
There's a 2-minute sign-up that emails you the link and a short survey afterwards.
Happy to get suggestions and answer questions in the comments.
