Looks great.<p>From what I can gather, the carpooling is done on a recurring basis, where it messages you every week day. I'd love to see a single use option.<p>My friends and I carpool all the time, but it's neither for school nor work. So, while a service like this would be extremely helpful (the process has gotten smoother for us, but it's still somewhat a hassle to coordinate), we would only have a use for it if we can initiate a carpool group on an as-needed basis. I'm thinking an interface where the service persists the group itself (names and numbers), but only sends out carpool messages when one of the group members requests it.<p>I suspect that this would also help with user acquisition since recurring services that text you can scare users away, especially if they're unsure about the service and want to give it a quick try.<p>Also: given that the service, as it is right now, does seem to be a recurring thing, you might want to add some information that makes it clear if/how you can leave a carpool group at any time. I wouldn't want to submit my number if I'm subscribing to a lifetime of carpooling reminders that I may no longer want.<p>I'll be keeping an eye on this project!
