Frequently asked

How do I add a city?

Tap Add a city on the main list. You can search three ways with the same box: by city name, by country name, or by time zone abbreviation — type PST, CET, IST, JST or GMT and you’ll get the cities in that zone. There are around 6,300 cities to choose from.

Some abbreviations show two different sets of cities. Why?

Because they genuinely mean two things. PST is both Pacific Standard Time and Philippine Standard Time, and IST is both India and Ireland. Meridian shows both rather than guessing which one you meant.

Why does a clock turn blue?

Blue means it’s night there — between 22:00 and 07:00 local time — so that person is probably asleep. The globe puts a small moon on those cities too. It’s the only colour in the list, on purpose: it’s there to say “don’t call them right now”.

Can I add the same city twice?

Yes, and that’s the intended way to use it. Add London twice and name one “Mum” and the other “Office”. Each entry keeps its own name.

How do I rename a city?

You’re asked for a name when you add it, and you can change it afterwards from the city’s own screen.

How do I work out a time for a meeting?

Open Convert and drag the timeline. Every clock flips together, up to 24 hours either way, so you can find the hour that works for London, New York and Tokyo at the same time. You can also jump to a specific date to plan around a trip.

My phone is in one country but I live in another.

In Settings, set a home time zone. It overrides what your phone reports, and every difference Meridian shows is measured from it. “Use device time zone” puts it back.

Can I switch to 24-hour time?

Yes — Settings, then the 12h / 24h control.

Does Meridian handle daylight saving?

Yes, automatically, using your device’s own time zone database. If a city’s clocks change, Meridian follows. Time zone rules do change, so keeping iOS up to date keeps the data current.

Does it need the internet?

No. Everything — the city catalog, the globe, the clocks — is on your device and works with no connection at all.

Does it need my location?

No. Meridian never asks for location permission. It reads your time zone from the system, which doesn’t require it.

Does it drain my battery?

It shouldn’t. There’s no background activity, no network use and no location use.

Is there an Android version?

Yes, and it also has home-screen widgets. Those aren’t on iOS yet.

Will you add widgets to iOS?

That’s the plan. If you want them, say so by email — it genuinely affects what I build next.

How do I delete my data?

Delete the app. Your city list lives only on your device, so removing the app removes all of it. There’s nothing on a server to delete, because there is no server.

Where does the city data come from?

From GeoNames, used under CC BY 4.0. The globe’s coastlines come from Natural Earth (public domain), and the icons are Feather (MIT). The full list is in the app, under Settings → About.

A city is missing, or its details are wrong.

Email me the city and country. If it’s wrong upstream in GeoNames I’ll correct it on our side in the next update.
