Thoughts on an iPhone app for bike touring

I’ve played around with a number of iPhone apps for cyclists. None of the ones I’ve looked at are really optimized for bike touring—instead, they’re mostly oriented towards fitness cycling, which has somewhat different goals.

An iPhone app for bike touring would need to overcome the problem of battery life and fulfill three main tasks. Battery life isn’t as big a problem as it is generally made out to be, but even in a best-case scenario, it would be difficult to get a solid 24 hours of use out on a single charge when using the iPhone as a bike computer for a big part of the day.
