CurrencyMate2 is a currency and tip calculator all in one, leveraging online currency rates and information about tipping in countries all over the world.
CurrencyMate2 helps you when you are sitting in the restaurant or the bar, to calculate not only how much the bill is in your own country's currency, but also details about what is customary to tip in the country you are now.
CurrencyMate2 has a tipping guide not only for restaurants and bars but also what is customary to tip at hotels and for services.
CurrencyMate2 works offline, meaning that it will try to synchronize currency rates when networking is available. You should, of course, be able to convert the currencies even when you're out in the jungle or in a vast desert.
With Family Sharing set up, up to six family members can use this app.
