About

Hourline

Features
Read full description

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 • Reorder cities — the first is home, and every offset is shown relative to it • Daylight saving and half-hour offsets handled correctly Built for the small, constant question: is it a reasonable hour to message or call someone right now? No account. No sign-in. No network requests at all. Your city list is stored on your device and is the only thing the app keeps.

Verdict

The call

The clearest difference is in-app purchases: Sphere Time at none against Hourline's 1. Sphere Time also leads on iOS requirement (9.3 vs 16.4). Hourline's advantage is update cadence (every 2 weeks vs every 5 weeks). On price, ads and device support there is nothing between them.
