UPDATES!!!
- Fixed a bugs with some of the time zones and conversions calculations.
- Added Temperature conversion.
- Added Fuel weight conversions based on 6.7 lbs per gallon of fuel. I understand that I may get a slew of emails telling me the weight is 6.8 or 6.776 lbs. This calculation is for reference use and isn't intended to be used to calculate the exact weight of fuel onboard. There are already overpriced computers that do that (and most of the time they just display dashes).
Advertising?
Help me advertise and tell your fellow maintainers/coworkers about 3-Level. Don't forget to leave a comment/review on the App Store.
Until the next update...See Work...Attack!

Just a quick bug fix version.
- Fixed the timezone for RAF Mildenhall and RAF Lakenheath.
So...what else is new.
- I have been getting plenty of requests to add the fuel weight calculator. Don't worry...it's coming. It'll be the first thing on my plate after I finish moving. Also, I'm working on a few other projects that will make life a bit easier on a few folks. Stay tuned.
- So what can you do? Send me things you want to see in the app. As always, I vet the recommendations to make sure it's applicable to the goal of 3-level. I can't put something in that doesn't follow the theme of the app. Although there really should be a notification system for travel vouchers as they make their way through the system...like they do with tax returns...but I digress.

-Fixed zulu julian date bug.
Also, I wanted to see how many different units are using the app so put your unit in the comments section so we can all see how far 3-Level has spread.
--In the works--
-UI Overhaul
-Maybe someway a midget can actually do the inspection for us.
-QA detector (wouldn't that be nice).

Added a few requests that I received from a couple of folks.
-Added Nautical Miles to conversion tab
-Added Pounds and Kilograms to conversions tab
-Added Liters and Gallons to conversions tab
Also worked on the details screen for each base. It's easier now to edit the details so if you want to add a base that is not listed in the master listing, you can always just add any base with that is in the same time zone and edit the name of the base. Another option would be to email me (from the link on the conversions tab) and I'll add it to the master list that way everyone gets the update and we all benefit.
On another note, I heard a rumor that our fellow maintenance folks at the 730th are getting some use out of the app. Good to see hear it's getting some use.
