Sometimes, I just have to shake my head in wonder. Over on #WillCycle, I built the frigging very best mapping system available for traffic-free cycle routes in the UK. Then I added treasure hunts (cos who doesn't like those?) and Fairy Trail (cos little kiddies deserve some magic in their lives).
I built the very unique #GPSart generator, and I built a decent cycle route builder. Then I added in seeing no ads, at all. And, to show how confident I am people will like it, I offer a FULL month's free trial. No risk, no cost! And after that, it's just 7p per day. And yet, tumbleweed...
This tells me 1 of the following is true: 1) You lot think it's not even worth trying out, for free, for a month 2) What I built is so rubbish, nobody will ever use it 3) You consider 7p per day to be a fortune 4) I've been exceedingly bad at telling you the benefits TO YOU.
I think the route planner is ace. It's a crowded market though and you're competing with the likes of ridewithgps, cycle.travel and komoot. Getting traction will be hard and I think you need to be patient.

cycle.travel | route-planner and maps - traffic-free & quiet roads

The best-kept secret of a great ride - find scenic routes with fewer cars.

Oh, I won't be adding to the route planner. I have no intention of competing with any of those you mentioned. In fact, originally, the route planner was going to be a back-end feature, only available to me. I aim for a different market segment to all those organisations, but I do have features none
of them have, plus several more features being planned (again, most of which nobody else has).
