Tipping shouldn’t be a source of stress. Whether you’re at a restaurant in Paris, a hotel in Tokyo, or a taxi in São Paulo, the rules are different everywhere — and getting it wrong can feel awkward at best, offensive at worst. Tip Zombie takes the guesswork out of tipping, no matter where you are in the world. KNOW WHAT’S EXPECTED, EVERYWHERE Tip Zombie covers 100+ countries with location-aware guidance tailored to local customs. It doesn’t just give you a number — it tells you the full picture. Some countries expect a percentage. Others prefer a flat amount. In many places, tipping is entirely optional. And in some, leaving a tip is actually considered rude. Tip Zombie knows the difference, and it tells you clearly. BUILT FOR EVERY SERVICE Tipping at a fine dining restaurant is nothing like tipping a taxi driver or a hotel porter. Tip Zombie gives you service-specific guidance across dozens of categories, including: -Restaurants and cafés -Hotels and porters -Taxis and rideshare -Spas and salons -Tour guides and excursions -And many more FOUR FLEXIBLE TIPPING MODES Every country is assigned the tipping mode that fits its culture: -Percentage — the standard for tip-expected countries -Flat Rate — for places where a fixed amount is the norm -Optional — when a tip is appreciated but never assumed -No Tip — for countries where tipping isn’t customary or is actively discouraged A clear banner tells you exactly what applies before you ever punch in a number. HANDLES EVERY CURRENCY, CORRECTLY Most tip calculators break on edge-case currencies. Tip Zombie doesn’t. It correctly handles: -Standard decimal currencies (USD, EUR, GBP) -Zero-decimal currencies like Japanese Yen and Korean Won -Three-decimal currencies like Kuwaiti Dinar and Bahraini Dinar No rounding errors. No awkward decimals. Just the right number. FLEXIBLE CALCULATIONS -Choose your tip percentage or enter a flat amount -Add tax or calculate on a post-tax total -Tip Zombie walks you through seven common input scenarios so the math always works the way you expect THE TIP GUIDE Not sure what’s appropriate?
