Device info: iPhone 4S, 64GB, OS 6.1, AT&T, latest app update (as of 11-23-12): Almost everything works fine, and I LOVE the calendar integration, but there is a problem with the Contacts integration. I selected several Contacts to add to the maps view, which worked fine, but when I went to find the added contact's locales I couldn't figure out how to have them viewed, at first - finally, I figured out you have to pinch & zoom out & then it shows you all their pins. BUT, my aunt, who lives in Spring Valley, California keeps showing up in Spring Valley, CANADA. I checked my contacts thinking maybe I'd mistakenly forgotten to put United States, but it was all entered correctly there, so it must be a glitch w/the app. Hope my device info listed above helps fix this glitch, devs? Also, devs, I would gladly pay an IAP to remove the ads! I appreciate the free app that is ad-based, but in this particular app, I'd prefer no ads - this app has a hefty handful of screen info & the ads just add too much, please consider an IAP to get rid of them? Thanks! As for the gentleman w/crashing problems, I've only had it happen once & all I had to do was use my Memory Clearing app & then it was fine. As well, some people don't realize that after the OS 5.0 update (or the purchase of the iPhone 4s), you can no longer just hit the round "Home" button @ the bottom of your devices to close out apps - you need to do that & then DOUBLE TAP the same round "Home" button & your iScreen will raise/lift/move up & show you all your open apps along the bottom, hidden underneath your iScreen. At this point, you need to press & hold down on one of them (same as if you were deleting one or moving it around on a regular screen), hold it until the red "-" signs appear & all the apps start to wiggle, then close each one out by tapping on the red "-" sign @ the top edge of each app. This will also clear your memory, but not completely. Turning the device off and back on again (AFTER doing the above), will reset your memory fully, BUT WILL NOT CLOSE ALL THE OPEN APPS, as I described above. (It's quite amazing to me how many people don't know this - it is VERY important to read the info Apple provides before each OS/iTunes update! It's all described very well in their verbiage.) Also, if my instructions are unclear, you can either visit the iTunes website for detailed info OR there are several VERY good iOS info apps available. A couple of the free ones are just as good as some paid ones, so read reviews before spending $ on a bad one! Hope this helps!
