Shell Notes vs Think First

Encrypted notes that never leave your device. No cloud, no account, no tracking. Shell Notes is a private, offline notes app with one sharp focus: keep your writing local, encrypted, and yours alone — in a fast markdown and code editor with a calm, dark, developer-flavored theme. · Real AES-256-GCM encryption (audited open-source crypto: @noble/ciphers, @noble/hashes), keyed off your passphrase via PBKDF2-SHA256. · A master passphrase only you know. No recovery, by design — there is no backdoor and no copy of your data. · App-lock with optional Face ID. · Plain text, Markdown,JavaScript, TypeScript, Python, JSON, Shell, HTTP and CSS syntax highlighting. · Folders, starring, pinning, full-text search. · Eleven monospace typefaces — JetBrains Mono, Fira Code, IBM Plex Mono, Source Code Pro, Ubuntu Mono, Inconsolata, Anonymous Pro, Space Mono, Roboto Mono, VT323, and a default UI font. · A subtle scanline overlay you can switch off. · No analytics. No advertising. No sign-up, no email, no phone number. · No cloud sync, no remote model calls, no leakage. Your notes, folders and search index stay on this device. Export your vault to JSON through the iOS share sheet whenever you choose — nothing leaves otherwise. Shell Notes protects your notes at rest, on this device, with strong encryption. If you forget your passphrase, your locked notes are gone — there is no recovery. If your unlocked iPhone is in someone else's hands, the app is only as safe as your iOS lock screen and the auto-lock setting you choose inside Shell Notes. For developers, journalists, and anyone who closes an app the moment it asks for an email address. Quiet, local, yours.

You reach for your phone – and 40 minutes later you no longer know why. Think First puts a short, deliberate moment right before that. No lecturing, no permanent lockout. The app stays closed until you have taken a moment – then the decision is yours. SETUP IN THREE STEPS • Pick your app from the list – around 70 well-known apps are built in • Link it in the system dialog so iOS knows which app you mean • Allow notifications – they take you from the blocked app to your countdown HOW YOUR MOMENT WORKS • You tap the app – it is blocked and shows its name • "Start my moment" sends you a notification • You tap it, the countdown runs, then you decide • Finally you set how long you need: 5, 15 or 30 minutes • The app then opens by itself – and locks again once your time is used HOW LONG DO YOU NEED? After the countdown you set yourself a time budget. Real usage counts, not the clock: if the phone sits on the table in between, your budget doesn't run down. Once it's used up the app locks itself again. YOUR APPS, BY NAME AND ICON Every protected app appears the way you know it: in statistics, in notifications and on the lock screen. So you see which app calls you how often – not just an anonymous total. WRITE DOWN WHAT YOU NEED IT FOR • Before the app opens you type, in one sentence, what you actually intend to do • Apple Intelligence reads along directly on your iPhone and checks that you really answered – not whether your reason is good enough • Later you see which sentence you tell yourself most often • Your text never leaves your device. Requires iPhone 15 Pro or newer with iOS 26 STAYING WITH IT, MADE REWARDING • Levels, XP and streaks for every impulse you win, 12 badges • Streak protection: once a week a day may drop out • Add friends and compare the week – free, up to 50 • Share your wins as an image: your numbers, your streak, your badges AT A GLANCE A home screen widget with your numbers per app – and one for the lock screen, right where you reach for the phone. EMERGENCY? SOS Press and hold the app icon, confirm three times: everything is open for 5 minutes. Then everything locks itself again – even if you never open Think First.
