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.)

Julian makes it simple to find any day of the year, convert dates, and understand your year at a glance on iPhone, iPad, and Apple Watch. Browse the calendar to explore past and future dates, or enter a day number to jump straight to the matching date. Choose the date format you prefer and instantly see the day of the year, year progress, days remaining, week number, and current quarter. Convert between calendar dates, ordinal dates, ISO 8601 dates, ISO week dates, Julian calendar dates, Julian Day Numbers, and Unix timestamps. Add or subtract days, weeks, months, or years, or calculate the exact time between two dates. Julian supports a wide range of astronomical and time counting systems, including CCSDS Julian Date, CNES Julian Date, Dublin Julian Date, Lilian Date, Mars Sol Date, Modified Julian Date, Rata Die, Reduced Julian Date, Truncated Julian Date, and Unix Time. Copy any date value with a tap, or copy and share a complete date summary. Save your favorite formats for fast access whenever you need them. Keep important date information visible with Home Screen and Lock Screen widgets. Customize their layout, colors, and content. Larger widgets can show additional date values and calendar views without opening the app. On Apple Watch, quickly view yesterday, today, and tomorrow, look up any day of the year, and choose complications that match your watch face. Use Siri to retrieve date values and check your year progress. Add Julian actions to Shortcuts to convert dates, perform calculations, copy results, and open detailed date information. Personalize Julian with seven color themes, alternate app icons, and System, Light, or Dark appearance. Set your preferred first day of the week and choose which month begins your first quarter. For an instant glance, enable the optional app icon badge to show the current day of the year. Badge updates are silent and do not create banners or sounds. Notification permission is required.

Verdict
The clearest difference is in-app purchases: Pilot Time at none against Julian's 3. Pilot Time also leads on iOS requirement (13.0 vs 17.0). Julian's advantage is ratings volume (4.6K vs 19) and rating (4.8 vs 4.5). On price, review sentiment, ads and device support 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
Both are free to download. Julian sells 3 one-off in-app purchases. Pilot Time asks for nothing beyond the download.
Julian holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Julian has 4.6K 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 65% of Julian'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, Julian every 2 months. The most recent releases landed on September 21, 2026 and September 22, 2026 respectively.
