About

Clocker App

Features
Read full description

See the time in multiple cities at a glance. Clocker keeps your world clocks on your iPhone, iPad, and Mac—no account and no cloud. Add up to 32 time zones and arrange them in the order you care about. The first zone is your large hero clock; the rest appear in a clear list below. Start from an empty home screen with a simple add flow, or build a full dashboard for travel and remote teams. Customize how each clock looks: digital, Roman numerals, or an analog dial; show or hide seconds, the date, city labels, and GMT/UTC offsets; pick time and date format styles; and adjust type size so everything stays readable. Choose an interface language among nine options and pick an appearance that fits you—from system light and dark to seasonal and stylized themes in Settings. Extras: on iPhone and iPad, add a Lock Screen widget to check your zones at a glance where the system supports Lock Screen widgets. Several themes ship with optional ambient sound—birds, water, wind, fireside crackle, and similar gentle loops—so you can pair time reading with a calm backdrop. In Settings you can also turn on an optional metronome with adjustable BPM; it plays a clear tick for focus or rhythm practice. Privacy: your saved zones and preferences are stored only on your device (standard app storage). The app is not built to send that data to our servers for the version described here.

The call

The clearest difference is price: Diag at Free against Clocker App's $3.99. Diag also leads on iOS requirement (13.0 vs 17.0). Clocker App's advantage is update cadence (every 2 weeks vs every 2 months). On ads, in-app purchases and device support there is nothing between them.
