Every memory starts with a plan. Syn9 lets you make plans, share them, and keep the photos — with family and friends. Choose who sees each schedule and note: family plans for family, weekend plans for friends. Schedules Choose who to share each event with — family schedules for family, friend plans for friends. Each event gets its own chat so you can coordinate without losing context. Reminders and recurring events keep nothing slipping through. Notes Share shopping lists, trip plans, and more — with whoever you choose. Edit lists together in real time so no one's grocery list is out of sync. Lock a note to require Face ID or your passcode before it opens on your device. Chat Tap any schedule or note to open its chat — never lose the thread. Group with friends-of-friends without exchanging contacts. Reactions, pins, and unread badges keep things organized. Albums Create an album from any schedule, note, or chat, and collect everyone's photos and videos in one place. The plan becomes a memory you can look back on. Friends Add friends easily via QR code or a shareable link. Set your go-to share list in advance to save time every time. Push Notifications Get notified instantly when a schedule, note, or message is shared with you. Never miss what matters. Koe (AI assistant) - Say "dinner tomorrow at 7" — Koe creates the schedule - "Share with my crew" — Koe knows your friends, groups, and the nicknames you use - Ask anything — Koe searches the web too Make everyday life with family and friends smoother and more fun. Give Syn9 a try. Some features require a Syn9 Plus or Max subscription: photo and video attachments, albums, recurring events, reminders, default share lists, note folders, note lock, and monthly Koe usage.
