Get Calcuttafy and run your next fixed-bid Calcutta/prediction pool the right way! Running a prediction pool shouldn't require a spreadsheet, a group chat, and a prayer. Calcuttafy is the all-in-one mobile app that makes it effortless to host and participate in prediction pools for any sport, race, office event, or competition you can imagine. No more chasing people for their picks via text. No more manual tallying of who picked what. No more brining your laptop on vacation just so you can manage pools for the group. Calcuttafy lets you focus on the event, not the paperwork! Hosts - set up your pool in minutes. Share a single invite code and let participants submit their picks privately — no one sees anyone else's selections until you declare results. You control the payout structure: configure the percentage split across first, second, and third place, and Calcuttafy automatically calculates parimutuel points distributions. Managing multiple pools for the same event? Group them under one umbrella event and share a single invite code that covers all of them — perfect for multi-race weekends, golf tournaments with multiple rounds, or any competition with several pools running simultaneously. When results are in, declare the outcome and let Calcuttafy do the math. Share results instantly with your participants right from the app. Participants - joining a pool is always free. Enter your picks confidentially and track how you're doing as results come in. Join via your host's invite code, with or without setting up an account. Great for golf tournaments, racing events, team sports, office pools, and any competition where participants pick a winner. ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Lifetime Access | $17.49 | one-time | | Event Pass | $1.49 | one-time | | Season Pass | $5.49 | one-time | ## Version history (last 5 releases) ### 1.7.5 — 2026-08-09 New auction pool type for a more traditional Calcutta pool experience.
