Built On Device
The interesting part of Atlas is what happens between opening the app and seeing a map. Every located photo is read for its date and coordinates, those coordinates are turned into place names, and the result is bucketed into visits, trips and statistics. All of it runs on the device and off the main thread, and it has to stay quick on a library of tens of thousands of photos.
