Offset

A guided onboarding walks you through the basics in four steps:

• Welcome — A brief introduction explaining that Offset lets you compare times across cities at a glance. You can add cities, drag the time picker to see shifts, and tap a card to set your reference point.
• Add Offsets — An interactive screen where you search for and add your first cities. A curated list of popular cities (New York, London, Tokyo, Sydney, Singapore, Paris, Berlin, and more) is shown by default. You can search from a database of over 33,000 cities worldwide. Free users can add up to 2 offsets during onboarding.
• Choose Clock Style — Pick between analogue and digital clock faces. This can be changed later in Settings.
• You’re All Set — Confirms setup is complete, with a mention of lists, widgets, and iCloud sync. Notes that lists are an Offset Pro feature.

A “Skip” button is available on every page except the last. Tap “Get Started” to finish onboarding.

During onboarding (step 2), tap a city from the popular list or use the search bar to find one. Tapping a city adds it (shown with a green tick); tapping again removes it.

After onboarding, you can add more cities via the ellipsis menu (top right) > “Manage Offsets” > “Add Offset”.

Open Manage Offsets from the top-right menu. Tap the ellipsis button next to any offset and select “Set as Home”.

The home city is always shown first in your offset list and is used as the reference point for time comparisons. Your home city is displayed with a house badge on its card.

Setting a home city requires Offset Pro.

In Manage Offsets, tap the ellipsis on the current home city and select “Clear Home”.

Tap the ellipsis menu icon (top right) > “Manage Offsets” > “Add Offset”. Search by city name using the search bar. The app searches a database of over 33,000 cities sourced from GeoNames. You can also browse popular offsets shown by default.

Tap a city to add it and it will immediately appear on your main screen.

Free users can add up to 2 offsets. Offset Pro removes this limit entirely — add as many cities as you need.

Either long-press an offset card on the main screen and select “Remove”, or go to Manage Offsets and swipe left on the entry or use its menu to remove it.

Offsets are automatically sorted by time — earliest first, based on the day offset relative to the currently selected timezone, then by the time of day, and finally alphabetically for ties.

Your local time and home city always appear in their natural position within this sort order, with the local timezone always included.

Yes. Long-press an offset card and select “Edit Name”, or go to Manage Offsets and tap the ellipsis on any entry to select “Edit Nickname”. Enter a custom name and tap Save.

To clear a nickname, tap “Clear” in the edit prompt.

Nicknames require Offset Pro.

The search uses full-text search across 33,000+ cities. If exact matches are not found, it falls back to a broader text search. Try searching by the city name itself.

If a small city is not in the database, try the nearest major city in the same timezone. All standard IANA timezone identifiers are supported.

Each card displays a city name, a clock (analogue or digital), the GMT/UTC offset, a solar state icon (sun, moon, sunrise, or sunset), and a relative date line (e.g. “Today”, “Tomorrow”, “+5 hrs”).

Cards are colour-themed to reflect the actual time of day at that location using real solar position calculations based on each city’s coordinates.

Tap any offset card to set it as your reference — an “Editing” badge appears on the card. The time picker at the top of the screen shows the time in that city.

Drag the time picker wheel to shift time forward or backward — all other cards update simultaneously, showing you what time it would be in every city at that moment.

Tapping “Now” resets the time picker to the current real time and enables live tracking. A pulsing green dot indicates that times are updating in real time.

Interacting with the time picker wheel disables live tracking so you can explore future or past times.

When you scroll down through your offsets, the time picker at the top collapses into a compact bar showing just the current time. Tap the collapsed time display to expand the picker again.

A tooltip appears the first time the picker collapses to explain this behaviour.

Yes. Go to Settings > Clock Style and choose Analogue or Digital. This affects how clocks are displayed on all offset cards. You can also select your preferred style during onboarding.

Clock faces and hands change colour based on the solar state at each location:

• Day — Light face with coral/sky-blue hands and a sun gold border
• Sunrise — Warm amber-tinted face with gold accents
• Sunset — Coral/rose-tinted face with warm accents
• Night — Dark navy face with silver hands and a moon-silver border

These solar-themed colours adapt to both light and dark modes. Night cards always use a dark appearance regardless of the app’s colour scheme.

Lists let you organise your offsets into groups — for example, “Work”, “Travel”, or “Family”. When you select a list, the main screen filters to show only the offsets in that list. Your local time is always shown regardless of which list is selected.

Lists are an Offset Pro feature. Free users can view existing lists (e.g. synced from another device) but cannot create, edit, or manage them.

Tap the ellipsis menu > Lists > “Manage Lists” > “Create List”. Enter a name and tap “Create”. You will then be prompted to add offsets to the list.

From Manage Offsets, tap the ellipsis on any offset and select “Add to List”. Choose the list you want to add it to.

Use the ellipsis menu > Lists and tap the list name. You can also swipe left or right on the main screen to cycle through your lists. A tooltip explains this the first time you filter by a list.

Select “All” to show every offset.

Go to Manage Lists, tap the ellipsis on any list, and choose “Rename” or “Delete”.

Deleting a list does not delete the offsets within it — they remain in your collection.

Offset provides three widget families:

• Offset Glance — The general-purpose widget. Available in small, medium, inline Lock Screen, circular Lock Screen, and rectangular Lock Screen sizes. Shows one or more offsets with solar day/night theme styling. Free users see a single analogue clock; Pro users can show up to 4 offsets and choose between analogue and digital styles. Configurable by specific offsets or a list.
• Offset Styles (Pro only) — A small Home Screen widget with three layout options: Badge (single offset with a prominent clock display), Clock + Sidebar (a primary clock with up to 2 additional offsets listed alongside), and Sun Path (a sun arc visualisation showing up to 4 offsets).
• Offset World (Pro only) — A medium Home Screen widget with five layout options: List (hero clock with up to 5 secondary offsets), Compare (side-by-side comparison of up to 5 offsets), Grid (up to 6 offsets in a compact grid), Day & Night (up to 6 offsets split into day and night groups), and Sun Path (a sun arc visualisation with up to 6 offsets).

Long-press your Home Screen, tap the ”+” button in the top corner, search for “Offset”, and choose your preferred widget size and style.

You can configure which offsets or list to display by tapping the widget after adding it.

Yes. Pro users see +/- buttons on Home Screen widgets that shift the displayed time forward or backward by one hour. This is useful for quickly checking “what time will it be in 2 hours?” without opening the app.

A reset button returns to the current time. By default, the time adjustment auto-resets after 3 hours. You can toggle auto-reset in Settings > Widget Time Adjustment.

The Offset Glance widget supports three Lock Screen placements:

• Inline — City name and time displayed as text (appears above the clock)
• Circular — Solar icon, time, and city name in a compact circle
• Rectangular — Solar icon with city name and time in a wider format

Your offsets, lists, and settings sync automatically across all your iOS devices signed into the same iCloud account. No setup is required — it happens in the background.

• Offsets and lists sync via SwiftData’s built-in CloudKit integration (automatic, per-record sync)
• App settings (clock style, selected offset, home city) sync via iCloud Key-Value Store

No. As long as you are signed into iCloud on your device and iCloud Drive is enabled, sync is automatic. If iCloud is unavailable, the app works entirely offline with local storage.

When you open Offset on a new device, your offsets and lists sync from iCloud. A green “Data Restored” banner appears briefly confirming the sync.

Yes. Go to Settings > Appearance and choose:

• System — Follows your device’s light or dark setting
• Light — Always light mode
• Dark — Always dark mode

This affects the overall app interface. Solar-themed card colours adapt to both light and dark modes — for example, night cards always use a dark navy background regardless of the app appearance setting.

No. Offset does not collect, track, or share any personal data. The app’s privacy manifest explicitly declares no data collection, no tracking, and no tracking domains.

• On device — Your offsets, lists, and preferences are stored locally using SwiftData and UserDefaults
• iCloud — If you are signed into iCloud, your data syncs via CloudKit (Apple’s private cloud database) and iCloud Key-Value Store. This data is stored in your private iCloud container and is not accessible to anyone else

No. Offset uses only Apple frameworks — SwiftUI, SwiftData, CloudKit, StoreKit 2, and the system SQLite library. There are no third-party analytics, crash reporting SDKs, or advertising frameworks.

The city database (sourced from GeoNames under a Creative Commons Attribution 4.0 licence) is bundled within the app. No network requests are made to look up city data — all searches are performed locally on your device.
