Version 1.3 we've got metric! Also fixes the "black background" issue encountered by some users & provides some basic instructions.
Version 1.2 brings an "About" screen. Contains a fix to code that presented the user with inaccurate results in situations with very short or very long ranges. Seriously considering adding metric support...soon!
Version 1.1 has arrived with the ability to save scopes and ranges, and hopefully crash less. Did it get uglier? Maybe. It's definitely still free. Enjoy!
