GV Places 1.1 Submitted To App Store

Yesterday, I submitted version 1.1 of GV Places to the App Store for review. I am hopeful that it won’t take as long to get through this time, but I’m not holding my breath.

The biggest news is that I dropped the iOS target version, so now people with Verizon iPhones can run it. I had hoped that the app store would not let someone download an app that they couldn’t run, but based on the 1-star review I got from a Verizon owner, that may not be the case. Here are the release notes

  • Should now work on Verizon iPhones.
  • Fixed a sorting/display bug that occurred when a place was autoswitched. The next time the app was run, the list would not be sorted properly.
  • Improved the region detection on iPhone 4. This should properly handle overlapping regions, which worked fine on the 3GS, but not so much on the iPhone 4.
  • Fixed a couple of memory leaks.
  • Note that when autoswitching is turned on, the app is not constantly running, looking for location changes. On the iPhone 4, it uses the region monitoring API, which means it tells the OS the regions it is interested in, and then goes to sleep. Whenever the phone enters one of those regions, the OS will wake the app up, telling it that it entered that region. This uses no extra battery on my iPhone 4, that I could tell. On the 3GS, it uses the significant location change monitoring API. With this API, the app tells the OS it is interested in significant location changes (this is mostly when cell towers change), and then goes to sleep. When one of these events occurs, the OS wakes the app up, telling it that a significant location change has occurred. The app then gets the current location and sees if it is within one of your places. If it is, it switches to that place. This is not as accurate as on the iPhone 4, but it’s all the 3GS has. This would probably use up a bit more battery than on the iPhone 4, because it has to do more work, but I didn’t notice any significant battery degradation on my 3GS.
  • Also note that autoswitching of places is NOT supported on the iPhone 3G, because neither of the APIs I described above were available on the 3G. Everything else works on the 3G.

  2. Thank you for the update! I found GV Places when I was wondering if an app that served this purpose existed, and yours was the [only!] answer.

    Have you considered an option to base location off of active WiFi access points? The idea here would be for quicker change over. Not sure if something like this is possible, but wanted to bring it up. Thanks again!
