PrincipleX vs OnceDone

Keep useful ideas from getting lost in your saved notes. Collect your own principles, reading excerpts and life lessons, then return to them with reminders and reflection. SAVE WHAT YOU WANT TO REMEMBER Write down a personal principle, a quote or a lesson from experience. Add its source and the context behind it. Build a personal library of ideas worth revisiting. ORGANIZE YOUR COLLECTION Use folders, tags and sources to bring structure to thoughts from work, reading and everyday life. SEE YOUR IDEAS AGAIN Choose daily reminders, pin a principle you want to keep in mind, or revisit it in a Home Screen widget. Set a rhythm that works for you. MAKE THE MEANING YOUR OWN Add reflections to each principle. When was it useful? What do you understand differently now? Keep the idea and your experience together. DISCOVER, SHARE AND SYNC Explore ideas to add to your library, turn a principle into a shareable image, and use iCloud sync across your own compatible devices. START FREE. UNLOCK ONCE. Save up to 20 principles for free. A one-time lifetime purchase removes the limit on adding principles, with no subscription. Signature Color and purchases to support the developer are separate, optional items and are not included in the lifetime unlock. Local prices appear in the app. Use Restore Purchases to check existing access. OPTIONAL SIRI ACCESS On supported systems running iOS 27 or later, you can allow Siri to find, read or open saved principles. Access to reflections is controlled separately. Availability depends on your device, language, region and system settings.

OnceDone keeps the practical details behind a task close at hand. Save an object or place, the method that worked, the things you needed, and the details worth remembering. When the same situation comes around again, follow one step at a time instead of piecing it together from an old note. Confirm what happened, add a change when needed, and build a more reliable record over time. Your records stay on your device. Add a cover photo, set a local reminder, search your archive, and share a text summary when it is useful. Lifetime Pro unlocks unlimited records, extra reference photos, printable QR labels, and complete ZIP backup and restore.
