SYLO is the app for the two of you: little appreciations that don't go unsaid, a weekly sync that takes ten minutes, dates you'll never fumble, and one shared place for everything life throws at you.

Notice the small stuff and say it. SYLO nudges you to send appreciations — and shows the balance between you, gently.
A ten-minute ritual that replaces the "we should talk about..." backlog. Prompts, shared notes, done.
Important dates feed a wishlist and gift loop, so anniversaries arrive with ideas attached — not panic.
Type anything on your mind; on-device AI files it into the right shared category — tasks, dates, pets, vehicles, home.
Invite your partner and share it all, synced privately through iCloud. Your household, not our servers.
An optional in-app pack for keeping date night interesting. We'll say no more here.
SYLO stores your data in your private iCloud database and shares it only with the partner you invite — using Apple's CloudKit sharing, end to end. The AI that sorts your brain dumps runs on your device. We don't run accounts, we can't read your data, and there's no tracking of any kind. The whole privacy policy fits on one page.
Native SwiftUI with the full iOS 26 Liquid Glass design language, CloudKit household sync, and on-device intelligence. No web wrapper, no login screen, no spinner farm — it opens fast and feels like it belongs on your phone.
