Write each principle as one short sentence. Principles resurfaces them at the right moments — a random draw every time you wake your phone, in a calm numbered list, and on Lock Screen and Home Screen widgets that refresh through the day.
No categories, no feeds, no clutter. If a principle fits in one line, it can steer a day.
Principles surface by chance — the “Now” card, the Lock Screen and Home Screen widgets — so they never wear into wallpaper.
No account, no tracking, no ads. Your words stay on this device and your personal iCloud (optional sync via Apple CloudKit).
Sign in to iCloud and your principles travel privately between your iPhone and iPad. We never see the data.
A quiet mist aesthetic for day and night, with Dynamic Type and full dark mode.
Localized interface, dates and example content — English, 简体中文, 繁體中文, 日本語, 한국어, Español, Français, Deutsch, Português (Brasil), Русский, Italiano.
Everything is free for 7 days from your first launch — every feature, no watermarks, no nagging. After the trial, a single one-time purchase unlocks the app for good.
No subscription. No renewal. Viewing your principles and the Lock Screen widget keep working forever, even unpurchased.
Touch and hold the Lock Screen → Customize → tap the area below the clock → search “Principles” → add “A Random Principle”. It shows one of your principles and refreshes hourly; tap the widget to draw the next one. The Home Screen widget works the same way: touch and hold the Home Screen → tap + → search “Principles” → add “A Random Principle”.
Adding and editing new principles requires the one-time $1.99 unlock. Reading your principles, the “Now” card and the Lock Screen widget keep working forever, even if you never purchase.
No. There is no account and no server. Your principles live on your device, and optionally sync privately through your own iCloud via Apple CloudKit. See our Privacy Policy.
