Dewit vs Cairn

Dewit is a minimalist plant watering reminder designed to help you care for your plants with ease. No complex plant databases. No overwhelming care guides. Just simple reminders and clear schedules. Whether you have one small succulent or a growing indoor jungle, Dewit keeps your watering routine organized and stress-free.

A quiet, private journal — and a way to find the patterns in your days. Cairn helps you write a few sentences each day. The on-device Apple Intelligence in iOS 26 quietly reads what you wrote and finds the patterns — your mood, the people who keep showing up, the things you keep returning to. Then, at the end of the week, it reflects the throughline back to you. Your words never leave your iPhone. No servers. No accounts. No analytics. No ads. Cairn is built for one person — you — and the model that reads your entries lives on your device, powered by Apple's Foundation Models framework. — Write a sentence or a page, your choice — Beautiful serif writing surface — the kind of paper you want to return to — Mood, people, places, and themes are tagged on-device, automatically — Patterns view: see your mood across the last 30 days, the things you wrote about most, your streak — Weekly synthesis (Premium): a single paragraph that reads your week back to you, honest and observant — never therapeutic — Home Screen and Lock Screen widgets — capture a thought from anywhere — Siri & Shortcuts: "Add to Cairn, I'm feeling…" — Daily reminder: one gentle notification at a time you choose, never more — Export to Markdown any time — your words belong to you CAIRN PREMIUM Cairn is free to use for as long as you like. Premium unlocks weekly synthesis, voice journaling, the Apple Watch companion, and four themes (Standard, Paper, Ink, Dawn) for the length of your subscription. — Cairn Premium Monthly: $4.99 USD per month, auto-renewing each month after a 7-day free trial — Cairn Premium Annual: $29.99 USD per year (about $2.50 per month), auto-renewing each year after a 7-day free trial — Cairn Lifetime: $99.99 USD, one-time purchase, no auto-renewal PRIVACY, AS A FEATURE Most journaling apps will quietly send your most intimate writing through a third-party API, store it on someone else's server, and use it to train a model. Cairn doesn't. Apple's Foundation Models framework lets us run a 3B-parameter language model entirely on your iPhone — fast, free, and offline. Cairn collects no data. Not your name, not analytics, not crash reports tied to you. Nothing leaves your phone — your journal lives only on this device. The result is a journal you can actually be honest in. REQUIREMENTS Cairn runs on iPhone with iOS 26 or later. The on-device AI features (mood tagging, weekly synthesis, voice transcription) require Apple Intelligence — supported on iPhone 15 Pro and later, and any iPad or Mac with Apple Silicon. On older devices, Cairn still works as a beautiful, simple journal. Subscription terms: payment is charged to your Apple ID at confirmation of purchase.
