Key features
What makes Casefile Daily stand out.
01
A new murder every day
Open the app and today's case loads automatically. Rain, smoke, and motive in twelve seconds—then the deduction grid appears.
02
Listen, then solve with logic
Narration plays with synced subtitles (or read the transcript). Six to eight clues narrow suspects, weapons, and locations on a 4×4 grid.
03
One correct answer—no guessing
Tap once for impossible, twice for confirmed. When every row and column locks, the case closes with a verdict line from your detective.
04
Replay the full archive
Today's case is always free. Unlock the calendar archive once to replay any past case from the catalog.
05
Share your streak, not the spoiler
Emoji-grid share cards show how you solved it—timing and pattern—without revealing the answer to friends.

Guides & resources
Casefile Daily guides for iPhone.
Practical reads that answer common search questions — each links back to the app.
A daily logic-deduction puzzle game in 1940s noir. Each case has hardboiled narration, a constraint grid, and exactly one valid solution. Built for a five-minute ritual, not a story campaign.
Is Casefile Daily free?
Yes. Today's case is always free with full narration. Ads appear after a case closes, before the share screen—never during play. Optional one-time purchases remove ads ($2.99) or unlock the past-case archive ($4.99). No subscriptions.
Does the app call AI at runtime?
No. Narration was generated before the app shipped and is bundled on your device. Nothing about you is sent to an AI service while you play.
What accessibility options are included?
VoiceOver across screens, color-blind mode with pattern marks, subtitles on by default, reduce-motion for smoke and rain, and separate narrator volume from music.
