iOS update / metric

I think it's great this app has been updated to iOS 8.
The unit converter is great, but the app would be even better if you could input data in metric as well as imperial.

Best Rigging calculator

Delbert Hall's original rigging calculator now updated for iOS 8. Shock load, resultant force, fleet angle etc. I use this app all the time.

Great App

Great Program. Hopefully the tool list will be expanded, but is still quite comprehensive.

Adding all sorts of reference tables (aircraft cable strength, shackle specs, etc) would be a definite plus. Maybe also a glossary of rigging terms.

All things considered, very useful.
