A couple of apps I like for travel in Europe are Omio, which has schedules for air, rail, and bus in one app with ticket purchase. It also knows about discount cards that can be purchased by seniors, for example. Free in the app store.
Moovit has excellent transit maps. The bus system in many cities is confusing. Often there is no overall maps of the transit system available online. Moovit will tell you what bus to take, literally walk you to the bus stop, tell you how many stops to your destination and then alerts you that your stop is coming up, at the stop before tells you your stop is next and then tells you to exit the bus at your stop. If there is a walk to your ultimate destination, it guides you there step by step, turn by turn. Free in the App Store.
If you travel frequently or even country hop on your annual vacation, you’ll love TripIt. Trip automatically receives all your confirmations for bookings, made online or made some other way. As long as your are mailed something about your reservation, TripIt gets it and adds it to your trip.
So you bus into the airport, your flight with Gate info and seat number, your train into the city center, you hotel reservation, and your dinner reservation all on ONE screen. If you have actually online tickets or Boarding Passes, TripIt will link to them. The Pro version costs an annual subscription fee and adds text notifications of delays and gate changes and help rebooking after a flight cancellation. But the basic app is free in the app store.
As to Google Maps versus Apple Maps, my vote goes to Google. Now that Apple allows deletion of built in apps, I have deleted Apple maps.
Google has over 1 million volunteer local guides submitting data. Google lends the 360 degree cameras in a backpack so they can gather Street View data from places motorized vehicles and bikes can’t go. Want a Street View of hiking the trail down into the Grand Canyon or walking into the Vietnam Veterans Memorial, Google Maps has got it. Google Maps also has a 3D perspective view with wireframes of the tall buildings and landmarks.
Not to mention Google’s network of photographers who make money filming the interior of businesses who are trying to improve their Google map listings.
Yeah, Google is going to use my data to sell ads most of which I will never see on my MacBook by an effective use of ad blockers. But Apple cannot compete with 1 million human reporters and Google Earth.
