One of the worst things about getting stuck with our car on the side of the road last week was not knowing where we were. In case you need a refresher, Eliot and I were driving south on the Sprain Brook Parkway last Wednesday in Westchester when our car just died.

When you drive long distances on a highway, you never know the activity, or lack thereof, at each exit. It might as well be a foreign country. There are billboards and highway information signs that spell out the big commercial enterprises, but that’s about it.

When the mechanic who helped us suggested that we drive to the next exit once the car started again, I went into a complete panic. He was going in one direction, we in another. What would happen to us if we were alone and nothing was there?

Worry no more everyone. The iExit Interstate Exit Guide app takes all the guesswork out of road trip pit stops. Hallelujah! We have been saved!

The iExit app identifies what restaurants, gas stations, hotels, and other services are available at each exit by name. It lets you search up to 100 exits ahead or even in another state for trip planning. It also allows you to filter by categories and brand/company names, and even to search for campgrounds and diesel or alternative fuels. iExit offers specialized information for RVers and truckers, including parking and where to find scales. And if all you’re looking for is a quick break, it also lists rest areas.

A “lite” version of iExit Guide is free for Android and iOS (iPhone, iPad), and the full version is currently $.99 for iOS.
