Centmap is a live map of beer prices and happy hours. Tap any bar to see what a pint costs right now, when the happy hour starts and ends, and what it will cost later tonight. Prices come from people drinking in those bars, so the map stays current in cities where a night out is expensive and menus change by the hour. Now covering Singapore, London, Bangkok, Hong Kong, Bali, Jakarta, Phnom Penh, Hoi An and the Gili Islands. WHY CENTMAP Bar prices are never static. Happy hours shift, weekend rates kick in, and a "beer" can mean a half pint, a bottle or a three-litre tower. Regular map apps can't tell you what you will actually pay. Centmap stores the real menus and works out the live price for the drink you want at the time you want it. WHAT YOU CAN DO • See live prices on the map. Every pin shows the calculated price for your chosen beer and size at the current time, and updates as the clock moves. • Look 12 hours ahead. Drag the time slider to see prices change as happy hours end, which bars close early and what your next stop will cost. • Filter by beer and size. Tiger, Guinness, Heineken, local craft or anything else on the menu, in half pints, pints, bottles, cans, jugs, towers, buckets and yards. • Set a budget. Cap the price per drink, set a minimum rating, or show only alcohol-free options. • Find the right bar fast. Search lists the cheapest pints, happy hours on right now, most liked bars, newest additions, latest edits and trivia nights. In Singapore you can also sort open bars by live air quality. • Open a bar profile. Opening hours, a happy hour countdown, the full drinks menu in local currency, photos, website and phone, and one tap to navigate in Apple Maps or Google Maps. • Save your favourites. Like bars to build your own shortlist. GOOD FOR • The 5pm exodus: check the blocks around the office and compare pint prices side by side. • Travel: land in a new city and know the going rate before the first round. • Late nights: past midnight, see what is still open and whether prices go up. • Specific missions: a pint of Guinness, a bucket of bottles, a tower for the table. BUILT FOR THE LOVE OF A GOOD DEAL Centmap runs on its community. Add a bar you know, fix a price that changed, or photograph a menu and let the built-in scanner read the beers and prices for you. Every contribution earns Centpoints. Climb from Bar Regular to Centmap Icon, and compete on monthly and all-time leaderboards for each city or worldwide. Trusted editors publish straight to the map; other submissions are reviewed before going live. You can browse without an account. Sign in with Apple or Google to contribute, save bars and join the leaderboards. Centmap is free and has no ads. Centmap started as one person's frustration with unpredictable bar tabs and the lack of honest menu data online. The goal is the most accurate and useful drink price index anywhere, so that a night out costs what you expected. Thank you for supporting the community, and happy mapping. -The Centmap Founder WHAT'S NEXT More cities across Asia and beyond are on the way. Follow Centmap for location drops.
