I've submitted a new version of Depth Gauge to the iPhone App Store. Other than being recompiled for OS 2.x backward compatibility, this update brings an enhanced version of Air Depth's EAD calculator. The Depth slider's range is now tied to the MOD of the gas.

Version 1.1 of Air Depth has also been submitted. Other than recompilation for backward compatibility, this is a cosmetic update.

UPDATE: Both updates are now available on the iPhone App Store.
