Stop converting time in your head! See local, military, and UTC time (GMT and Zulu time zones) with a tap. Developed by pilots who can never remember the current UTC (GMT/Zulu) time conversion, Pilot Time instantly gives you the current time and date for your zone, plus UTC time. Pilot Time can: - Compare the time and date at your current location (in 12-hour format and 24-hour format) to UTC time. - Show the 3 time zones you looked at most recently, plus UTC time. - Quickly convert any past, current, or future time to or from any time zone (including GMT). And selecting time zones is easy: first find the continent, then the city you want. No more mental calculations. (The time is provided by your phone's operating system, not a central server. Time zones are taken from the IANA Time Zone Database.)

This app converts a date between Julian Day of Year and Gregorian. For example, September 11, 2022 converts to 2022-254 and 2022-254 converts to September 11, 2022. This app will convert both directions. Julian Date for this app refers to the day-of-year number (more properly, the ordinal date) in the Gregorian calendar, often used in mainframe computer systems, the military, and the food industry. (Note: this app does not used the term Julian Date to refer to the astronomy definition which is calculated from 4713 BC) Features a simple clean interface with pickers for the dates. The app also features a monthly view allowing a quick view of both Gregorian and Julian days for the entire month. Widgets are available for both the Home Screen and the Lock Screen to display the current day of year. A Watch app is available that includes a date converter and complications to display the current day of year. Note: The app's icon does not change to reflect the current day.

Verdict
The clearest difference is price: Pilot Time at Free against Julianator's $0.99. Pilot Time also leads on iOS requirement (13.0 vs 17.4). Julianator's advantage is rating (4.7 vs 4.5) and update cadence (every 3 months vs every 6 months). On review sentiment, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Pilot Time is free to download; Julianator costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Julianator holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Julianator has 117 ratings behind it against 19, so its average is the more settled of the two. Written reviews complicate that: 73% of Pilot Time's written reviews are positive against 70% of Julianator's, so the app with the better star average is not the one people write more warmly about.
Pilot Time ships an update every 6 months, Julianator every 3 months. The most recent releases landed on September 21, 2026 and September 19, 2026 respectively.
