Kassandra is the social prediction app for people who actually have faith in their opinions. Everyone talks. Almost no one keeps receipts. Kassandra is built for the people who want a public record of every call they've made - the hot takes, the risky takes, and the ones nobody else saw coming. HOW IT WORKS ▸ Write a prediction. Anything. Sports, tech, music, culture, politics, finance, your friend's relationship - if you have a take, lock it in. ▸ It gets timestamped and locked forever. No edits. No deletions. No quiet rewrites of history. The record is permanent. ▸ When the call lands (or doesn't), the community votes. Did it come true? How bold was it? Your "Called It" score is decided by the crowd. ▸ Build a profile that shows your hit rate, your biggest calls, your streaks, and your category specialties. Climb the global and friends leaderboards. ▸ Share the receipts. Every prediction generates a clean, shareable card designed for Twitter, Instagram Stories, and group chats. WHY YOU'LL LIKE IT → Permanent record. No screenshots required. The timestamp is the proof. → No karma farming. No upvotes. Just whether you were right. → Categories for everything: NBA, NFL, F1, Music, Tech, Crypto, Politics, Culture, and more. → Vote on other users' calls before they resolve. Get vote rights, build community. → Heat scores reward bold calls more than safe ones - being right about an obvious thing is worth less than being right about a long shot. KASSANDRA PRO Free users get 3 predictions per day. Upgrade to Kassandra Pro for: ▸ 25 predictions per day ▸ Custom themes for your shareable receipt cards ▸ Premium profile analytics (hit rate by category, streak history, biggest calls) ▸ Verified Predictor badge at high accuracy thresholds Pro is available as a monthly ($4.99) or annual ($39.99) auto-renewing subscription. Built for people who back themselves. Make the call. Live with it.

Verdict

The call

The clearest difference is ads: Kassandra at none against Letterboxd's shown. Letterboxd's advantage is ratings volume (88K vs 1) and chart position (#20 vs unranked). On price, rating, in-app purchases and monetization model there is nothing between them.
