Review momentum
20/100
faster than 0% of Utilities apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
About C-130 Duty Day Calc
A C-130 Duty Day Calculator for crews hauling Uncle Sam's stuff around the world.
This app will quickly help you calculate all applicable duty day restrictions in both Zulu and Local time zones. Simply enter the Alert, Show or Takeoff time and all Vol-3 restrictions will be instantly calculated for you. No more complex calculus at the end of your duty day.
NEW: You can now add your own timeline to the app. Add your personal or squadron timeline to the latest addition. The tab can be tied to other calculator pages or work as a standalone tool for you planning your duty day.
It also includes a time calculator that allows you to calculate start, duration or end time when given the other two. Including the 781 decimal duration.
Hope you find it useful. My email is included if you have suggestions for improvements.
