UPDATE: Air Depth is no longer available. Check out Gas Manager on the App Store.
UPDATE: Air Depth 1.3.1 is available. No more crashing on iOS3.x. Thanks for your patience.
Version 1.3 of Air Depth contained a crash bug related to an iOS4 framework. I’ve already submitted 1.3.1 to fix the issue. 1.3 was approved in 12 hours, so I hope 1.3.1 is approved within a similar time frame.
The issue manifests on iOS versions less than 4. iOS 4 is released on 21 July. However, 1.3.1 will fix the issue for all prior iOS versions if you don’t intend upgrading to iOS 4.
Sorry for any inconvenience.
