Earphone Problem

First of all, this app is phenomenal. Second of all, whenever you open the app, and have earphones in a very loud and painful high frequency noise is emitted. I was wondering if you would be able to fix this problem as soon as possible. Thanks

When will you deliver the promised (“in a few weeks”) color flash temperature? I bought the unit because of this promise. Modern DSLRs deliver a fine metering option via the histogram, or I have a handheld meter I’ve used since the 90s to measure exposure/contrast. What I wanted was accurate color temperatures when I’m in a rented environment to make my workflow easier, which you promised but have yet to deliver.

Misleading title

No price is shown, but description refers to a color meter which is apparently an expensive add on. I had a free one that was great, but it was removed from the App Store. Color meters are built in some phones and a simple one would be worth while, but not for $300!
