Questions

Does it work offline?

Yes. Country facts, plug drawings, time zones, typical monthly temperatures, packing lists and the passport check are all on your phone. Only the current weather and exchange-rate updates need the internet. The last rates are saved with their date, so the converter keeps working; it warns you when they are more than a week old. With no connection, the current weather says "No internet connection".

How do I change my home country?

Tap the gear button on the Country tab, then Home country. Everything is compared with it: plugs, voltage, time, money and driving side.

Why does it say I need an adapter when my plug fits?

Many countries have more than one socket type. The app lists every type in common use and tells you which of your home plugs fit. Some hotels have universal sockets; an adapter is still the safe choice.

Does it tell me if I need a visa?

No. Visa rules depend on your passport, the purpose of your trip and how you arrive, and they change often, so the app doesn't guess. The Entry tab checks your passport's dates against common rules (6 months' validity, and the Schengen area's 3-month and 10-year rules) and opens the official entry requirements from your government: GOV.UK, the US Department of State, the Government of Canada, Smartraveller, SafeTravel, Ireland's Department of Foreign Affairs or the Hong Kong Security Bureau. For other home countries it opens the IATA Travel Centre.

Where do the facts come from?

Open data (mledoze/countries, GeoNames, the IANA time zone database, NASA POWER), Wikipedia's tables of plug types and emergency numbers, and our own research, all reviewed by hand. Current weather is from MET Norway and exchange rates from ExchangeRate-API. The app's About page lists every source and licence. Always check official sources before you travel.

How are packing lists made?

A new list starts with everyday basics (or one of your saved templates), adds items for the trip types you choose (beach, cold weather, business, hiking, with kids), then what this destination needs compared with home: a plug adapter, local cash, water tablets, and clothes for the typical weather on your dates.
