I thought this might be interesting - but I'm on PC and there are no quick ways to pop on that site and see the app in action. Like no screenshots or anything? So I left and likely will never be back. Always good to have some quick screenshots/gifs of apps in action or people bounce on your landing/sales page never to be seen again.
very interesting. I'd echo the comment by another user that the website needs to 'show' what the app UI is like.
The marketing aspect of the app would be key - the app store is crowded for convoy tracker apps - but hardly anyone is framing the "friends" angle. Good luck!
