Free to start. Build a cairn one stone at a time, slips included. Emergency Mode is always free. Premium adds an AI coach, journal search and more. Cairn is a quiet, private companion for quitting porn. A cairn is a stack of stones left on a hard trail to show the next person the way. In Cairn, you build one. Every day you show up, every check-in, every urge you get through adds a stone. A slip adds a weathered stone: dark, worn, still part of the structure. Nothing you build is ever taken away. NO ACCOUNT. NO EMAIL. Cairn doesn't ask who you are. There is no sign-up, no password and no real name. Your history is tied to your install, not to an identity. You can erase everything from Settings whenever you want. FREE, FOR REAL • Your cairn: the heart of the app, free • Daily check-ins for mood, energy and urge level • Emergency Mode: grounding tools for the hard moment, always free • Journal with a daily prompt • Slip debriefs: log what happened without losing anything • One small mission a day • Progress: honest weekly summaries worked out from your own data. Nothing here is a prediction. CAIRN PREMIUM (OPTIONAL) • Rowan, an AI coach you can talk to at any hour. Rowan is an AI, not a person and not a therapist. • Search across every journal entry • Your busiest hours, from your own urge history HONEST BY DESIGN No invented statistics, no fake testimonials, no free-trial tricks. You see the price before you buy, and you can cancel in two taps from your Apple Account. IF YOU NEED SOMEONE NOW Cairn is not a crisis service. The app lists free, confidential helplines for the US, Canada, UK, Ireland, Australia and New Zealand, plus an international directory.
