An iPhone, Apple Watch and iPad app to see Local and Zulu time (GMT) or multiple time zones in a single glance. Includes Widgets for both the iPhone and Apple Watch. Useful for pilots in getting weather briefings and filing flight plans, or Ham radio operators to do timezone conversions. No more worrying about getting the timezone offset correct or Daylight Savings Time conversions. Easily convert from different time zones, including times in the future or past. On the iPhone: - Home and Lock Screen widgets - The Zulu Time page gives a quick view of both Zulu and Local times - The Offset Time page allows you to see Zulu and local time either in the future or past by entering an offset via the Offset button. Tapping either Zulu or Local times will allow you to enter a time in the future or past, synchronizing both Local and Zulu times with that offset. The offset only applies to this view (except on the iPad the offset applies to everything on the page) - The Multiple Zones page allows you to add as many time zones as you wish in a scrolling view. Clicking on any Time Zone will allow you to change it. on iPad: All information is combined on one screen. You have user customizable time zones on the right hand side. On the left, you have Zulu and Local time and one customizable time zone. The offset to see future or past time can be done via the Offset button or tapping any of either the Zulu, Local or Custom time buttons on the left. On the Watch: Complications available in all watch faces making for glanceable ZuluTime and access to the app, which gives offset able time computation.
Strap Angles
This app helps measure the floor and centerline angles of cargo straps using your iPhone or iPad. It guides you through a simple calibration and measurement process, allowing you to share the results and perform a reasonability check.
- Calibrate device orientation
- Measure floor and centerline angles
- Share angle measurements
- Reasonability check for measurements

Measure the floor and centerline angles of a cargo strap by following a 2 step process: STEP 1 - CALIBRATE The first step is to calibrate the initial position and orientation of your iPhone or iPad. Calibrate by placing your iPhone or iPad flat and level next to the strap's tie-down fitting (double stud fitting or ring), pointing the top of the phone in the aircraft's forward direction, and tapping the red arrow button. STEP 2 - MEASURE The second step is to measure the strap's floor and centerline angle by moving the iPhone or iPad to the strap Place the edge of your iPhone or iPad against the strap while pointing the top of the iPhone or iPad towards the strap's first contact point with the cargo and pointing the bottom of the phone towards the strap's tie-down fitting. Tap the orange arrow button to lock the measurement. SHARE Tap the Share button on the app's bottom toolbar to copy, save, text, email, AirDrop, post, or send the angle measurements. Enter the strap's identification number if you need to keep track of different straps. REASONABILITY CHECK Before using your measured floor and centerline angles to determine strap restraint capability, you must do a reasonability check which verifies that the measurements represent reasonable angles of the strap. For example, if a strap is installed so that it looks close to straight up and down, a reasonable value for the floor angle measurement would be 80 to 90 degrees. If a strap is installed so that it looks like it extends in the forward direction along the floor, a reasonable value for the centerline angle would be from 0 to 10 degrees, and a reasonable value for the floor angle would be from 0 to 10 degrees. If either your floor angle or centerline angle measurement does not appear reasonable, then do not use the measurements and determine why there is an error.
