Dotty

A private notebook where everyone you know gets a page, including you. Contact apps store phone numbers. Dotty stores the things you would never put in a contact card: that she hates surprise calls, that his sister is called Ada, that his dad had surgery and you should ask. Everything is encrypted on your device. You do not need an account, and nothing leaves your phone unless you decide it should. EVERY PAGE IS YOURS TO SHAPE • Notes, lists, checklists, custom fields, files and folders, mixed in whatever way that person needs • A page for a friend looks nothing like a page for a client, and both are right • You get a page too, for the things you want to remember about yourself THE MAP Your relationships are not folders. The map draws them as a network, so you can see how they actually sit. • People move closer as you stay in touch, and drift apart when you do not • Someone can be family, gym, and work at the same time. You create the circles. • Drifting shows who you have not spoken to in weeks, before it becomes months MOMENTS • Birthdays repeat every year on their own, pulled from the person’s page • Reminders repeat when you want them to, like a monthly call or a yearly anniversary • Plans stay on one calendar, with everyone on it • Notifications for events, birthdays, and reminders PRIVATE, EITHER WAY You choose where your people live: on this phone alone, or in an account that follows you. • On-device only means there is no account and no copy stored anywhere else • The database is encrypted with SQLCipher, using standard cryptography • The key stays in your Keychain, marked for this device, and is left out of every backup • Photos and attachments are excluded from backups too, so no readable copy reaches iCloud • Sign in with Apple or Google if you want to sync. There is no password to lose. • No analytics, no ad SDK, no data brokers. Nothing you write is sent to any AI model, and search runs on your device • Export everything as a single file whenever you like, and delete your account in the app, iPhone and iPad.

Verdict
The clearest difference is in-app purchases: Memomium at none against Dotty's 1. Dotty's advantage is iOS requirement (15.1 vs 17.4). On price, update cadence, ads and device support there is nothing between them.
