Finding parking or hailing taxis, looking for food, and finding baggage claim are just some of the hassles air travelers have to deal with. TravelNerd is a comprehensive site and an iOS app with all the information you need for getting to or from the airport and around inside it.

Select your airports and TravelNerd will show you detailed terminal maps, as well as restaurants, shops, airport lounges, and amenities such as Wi-Fi availability, family bathrooms, and ADA info for people with disabilities. If you need help with transportation, TravelNerd also provides a list of shuttle options and taxis with phone numbers, as well as public transportation information and nearby parking options.

The level of detail is great: You can filter restaurants by those that serve alcohol or are child-friendly, for example, get airport lounge hours, and access coupons for some companies (e.g., parking discounts).

TravelNerd is similar to the popular GateGuru Android and iOS app, but is a bit different, with the to/from transportation information and highlights for special travel needs. It also works on any mobile device or on your desktop. (GateGuru's latest update also seems to have disappointed quite a few users.)
