Zulu Time brings Zulu (UTC), local time, world-clock planning, UTC alarms, and original instrument-inspired displays together in one focused app. AT A GLANCE β’ View live Zulu and selected local time side by side. β’ Configure Zulu and local time independently: 24-hour, 12-hour, or military format, optional seconds, and separate date styles. β’ Detect your current time zone automatically and refresh it as needed, or manually choose from 111 countries/regions and 126 cities and aviation hubs. PLAN THE SAME MOMENT WORLDWIDE β’ Select an exact UTC date and time up to seven days ahead or behind. β’ Move by 15 minutes, one hour, or one day. β’ Compare the same moment across saved world clocks with UTC offsets, DST status, and day-boundary indicators. β’ Read ISO 8601, aviation DDHHMMZ, and YYDDD ordinal codes.

ORIGINAL THEMES β’ Choose from 17 brand-neutral designs: six modern aviation displays, seven premium analog dials, and four minimal themes. β’ Supported aviation themes can use the on-device compass for live heading; heading scales in other themes are decorative. β’ Premium dials display both Zulu and local time without covering the dial. IPHONE, IPAD & APPLE WATCH β’ Configurable Home Screen, Lock Screen, and StandBy widgets. β’ A full Apple Watch app with all 17 themes. β’ Zulu/local and Zulu/date complications. β’ Sync the selected place, time zone, theme family, and verified subscription status from iPhone.

Verdict
The clearest difference is in-app purchases: Appgate RBA Authenticator at none against Zulu Time's 1. Appgate RBA Authenticator also leads on iOS requirement (11.0 vs 17.0). Zulu Time's advantage is update cadence (every 4 days vs every 14 months). On price, ads and device support there is nothing between them.
