It's a motorcycle focussed sat nav app, that runs on your smartphone, with loads of features. You can plan twisty routes to a destination, put in a duration and a direction and it'll plan a ride, via the twisty bits and you can put in a destination and it's plot a twisty route there and a different twisty route back. You can import GPX files and share routes with other Calimoto users. All this is available on the free version, what is restricted in the free version is the geographic zone. A one off fee of £39.99 (or 4.99 a month) opens up all the maps, plus speed cam alerts and ride analysis. Bear in mind you'll need a phone holder too.
I'm seriously impressed with what I've seen so far with the free version on a few local runs. So Impressed, I'll probably stump up the cash and it may even replace my sat nav. https://calimoto.com/en
