Cairn: Journal & Mood Tracker

Cairn is a private journal that lives entirely on your phone. No account. No cloud. No tracking. Everything you write — and everything Cairn notices about it — stays on your device. WRITE HOWEVER YOU WANT Type it, speak it, or scan a handwritten page. Cairn turns voice notes and photos of your notebook into entries, all processed on-device. Your audio and images never leave your phone. NOT SURE WHERE TO START Tap "Help me journal" and Cairn asks one gentle question at a time, helping you find the words — then keeps them as your entry. EVERY ENTRY IS A STONE Over days and weeks, your entries stack into a cairn — a quiet marker of the road you've walked. Cairn reflects your moods, your recurring themes, and the patterns you might not notice yourself: a Trail of your days, a Mood Map, a feel for your Terrain. GENTLE WHEN IT COUNTS Cairn reflects, it doesn't diagnose. No labels, no scores pretending to be clinical truth. On the hard days, it sets the analysis aside and simply makes room. PRIVATE BY DESIGN - Fully on-device — works offline, no sign-up - Nothing is uploaded, shared, or sold - Lock your journal behind Face ID WHAT IT COSTS Cairn is free to download, and everything is open for your first 14 days. After that, a single purchase unlocks Cairn permanently — one payment, no subscription, now or ever. If you don't buy it, nothing you wrote is taken away: your entries stay readable, searchable and exportable for as long as you keep the app. The unlock is for what comes next — new entries, reflection, and the patterns Cairn draws from your writing. Bought Cairn before it went free? It stays unlocked. You'll never be asked to pay again. Journal. Reflect. Grow.
