No illuminati was consulted for this app. ComploDex is the living archive of conspiracy theories. A playful collection of case files, signed by Les Petits Complotistes. You read both sides. You vote Plausible or Paranoid. You build your own Investigation Wall. Every day, a new file awaits. // ON EVERY SCREEN iPhone, iPad and iPhone Duo. The app follows the fold: unfolded, the grid stays visible while a file opens beside it; half-opened, each half of the screen has its own job. Nothing is stretched, everything is recomposed. // DISCOVER A new file every day, sealed until midnight. PROVEN cards (documented facts) or THEORY cards (hypothesis) — illustrated and sourced. Come back daily: your STREAK climbs, and at 7 days your file is guaranteed Rare or better. Missed a day? Roch keeps the thread warm. // DECODE Each card lays out the sources, the story, and four contradictory takes: Nino the Naive, Milo the Jaded, Max the Skeptic, Fiona the Intuitive. The Oracle keeps his angle for Initiates. Your job — cross-check the sources and make your own call. // VOTE Plausible or Paranoid? Your vote joins the POPULAR VERDICT from the community. Binary, simple, transparent. // INVESTIGATE Build your Investigation Wall: pin your cards, connect them with LINK Mode, share your thesis. 4 rarities to collect. Investigation categories for every taste — from Space to Surveillance, Paranormal to Cryptids. // CLASSIFIED Hidden investigations connect the files. Pin the right cards on a wall, link them… and the FILE CLOSED stamp drops. Can you crack them all? // FOUNDING INITIATE — limited edition, 30 seats Support the project with the Lifetime Founder edition (one-time payment) or the Initiate subscription (monthly or yearly). Personalized Founder Card + all Premium perks. The Founder edition is limited to the first 30 sign-ups, in the first month post-launch. // THINK FOR YOURSELF Our rule: read both sides, cross-check sources, make your own call. A friendly entry point to critical thinking — not a courtroom, not a pulpit. // PRIVACY-FIRST No ads. No chat. No public profile. No user uploads. Data hosted in France (Paris).
