Tap And Go!
chizuatter is an iPhone/Android application which aims to quickly find specific places around you.
"I need to get some work done before the next meeting but I need somewhere I can use a power outlet."
"Hmm. I need to kill some time... Is there a cafe near here?"
"Oh no! NATURE CALLS! NATURE CALLS!"
"Uh-oh, not much fuel left. Where is the closest gas station?"
Now, you don't need to worry about being stuck in such a situation. With chizuatter, you can find a place you want to get to by tapping chizuatter on your iPhone/Android and selecting an item from the list. It's as easy as that. If you select a keyword, the Maps app will be launched and show you the closest places corresponding to the keyword. If you select a My Map item however, then a custom map will be displayed and by using the contents of that My Map, will display results closest to you!
A few convenient My Maps you can use include Cafes with usable Power Outlets in Shinjuku, Shibuya, Chiyoda (by Cafes with usable Power Outlets - Japanese) or Evacuation sites in Tokyo (Created after the Eastern Japan Earthquake) or any other public My Maps.
A page is available with links to a number of convenient My Maps and keywords for you to add to your chizuatter iPhone/Android application. Please feel free to contribute to the page with any other useful My Maps or keywords that you discover.
