2.0 is past testing at this point, thanks for the offers. The next major release will need more testers though. I have no idea when that will be, it sort of depends on what people want added. At this point the only thing that I have not really added that I can think of is support for both imperial and metric. This is because I am still trying to decide how to implement it. Once 2.0 hits let me know if you find something missing!
I am hoping it will be up in a week or so. If you have already bought 1.0 it will show up as an upgrade as soon as it becomes available on the app store (once Apple approves it).
