Hourline puts a working-hours comparison on your home screen. Each city gets a strip of hours running from four hours back to eight hours ahead. Every column is the same moment in every city, so reading straight down tells you what time it is in each place — and whether anyone is awake. Color does the rest. Easily see working hours, early morning, evening, and night. Finding a window where three cities are all in daylight takes about a second. • Live clocks that tick continuously, to the second • Up to seven cities, in medium and large widget sizes • The current hour underlined in every city • A day marker when a city is on a different date than yours • Search any city or IANA time zone, in any of the eight supported languages • Reorder cities — the first is home, and every offset is shown relative to it • Daylight saving and half-hour offsets handled correctly • Light and dark appearance, following your system setting Built for the small, constant question: is it a reasonable hour to message or call someone right now? No account or sign-in required. Clocks, time zone comparisons, and widgets work offline. Your city list and preferences are saved on your device.

Verdict
The clearest difference is in-app purchases: TimeZone Expert at none against Hourline's 1. TimeZone Expert also leads on update cadence (every 5 days vs every 2 weeks) and device support (3 vs 1). Hourline's advantage is iOS requirement (16.4 vs 18.0). On price and ads there is nothing between them.
