O mu Bu mu? This or That

Dilemmas & bracket tournaments

Free · In-App Purchases · Designed for iPad. Not verified for macOS.

New in 2.0: bracket tournaments, your own brackets, the same draw with friends. 2,600 photo options, 200+ dilemmas. O mu Bu mu? ("This or That?") is the game that starts the argument at the table. Two photos, one tap: you pick, then see what everyone else picked. Then move on to a bracket and find the best. DILEMMAS • 200+ photo dilemmas: coffee or tea, sea or mountains, city or countryside? • Vote, see the split, move on. A new dilemma of the day, every day. • Sports, movies, music, food, travel, tech… 12 categories. BRACKET TOURNAMENTS • Real single elimination: Round of 64, 32, 16, quarter-finals, semis, final. • Food, desserts, drinks, cities, holiday spots, colours… 2,600+ photo options. • The champion's road, the full bracket tree and a shareable result card. • Crowd favourite: which option has been crowned most often? WITH FRIENDS • Turn any bracket into a code and send it. Everyone plays the same draw whenever they like. • Champions side by side: who picked what, and how much you agree. YOUR OWN BRACKETS • Your topic, your photos: office snacks, family holiday spots, the class's best movie. • Only people with your link see it; it never lands in anyone else's feed. NO SIGN-IN REQUIRED • Play right away. Link Apple or Google if you like: your brackets and champions follow you to a new phone, and friends see your name. Content is currently in Turkish; the interface is in English and Turkish. PRO (OPTIONAL, ONE-TIME) • No ads, unlimited own brackets, up to 64 options per bracket. No subscription; buy once, keep forever. Privacy Policy: https://berkalparslan.github.io/privacy/o-mu-bu-mu/ Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

The Apple Watch app is here. • Dilemma of the day on your wrist: vote and see what everyone picked. • Quick tournament: Round of 4, 8 or 16 — a champion in a minute. • The same tournaments and the same draw as the phone. 2.0 is a full rewrite. • New design: everything on one screen. • Real Round of 64/32/16/8 brackets, tree view and the champion's road. • Friend brackets: share a code, everyone plays the same draw, champions side by side. • Your own brackets with your photos, shared by link. • Optional Apple / Google sign-in. • Dilemma of the day, streaks, English interface.
