Offline-first at the venue
EventSync: reads and writes to a local on-device database, queues edits, and syncs automatically when the connection returns — conflicting or stale edits can require review.
Keep saved wedding-day details available on your phone, with role-specific tools and a personal section order that fits your workflow. Review planned timing beside recorded status, and use planner-reviewed recovery when the plan needs attention. Connected team updates catch up when service returns.

Barn, mountain, beach — the prettiest venues often have the worst reception. A web login or an iPhone-only app leaves half your team stranded. A native, offline Android app keeps saved timeline and contact information available, then syncs the moment you're back on.
Compare the mobile, offline and role features your team needs. EventSync provides a native Android app with saved day-of details and role-specific tools.

Being native and offline is the price of entry. These are the things EventSync does once the day is moving.
EventSync: reads and writes to a local on-device database, queues edits, and syncs automatically when the connection returns — conflicting or stale edits can require review.
EventSync: every crew and guest role gets its own board driven by the event's real timeline and guest data — the caterer sees guest dietary flags with table labels and covers by meal.
EventSync: role-relevant reminders and role-targeted broadcasts — native notifications, not scheduled texts or email.
EventSync: when a block runs over, SmartRipple previews updated timing across downstream blocks; an authorized planner or team lead reviews and applies it — included with Day-Of at no extra charge.
SmartRipple recovery is free with any Day-Of access; the Wedding Day Assistant is a paid upgrade.

Yes. EventSync is a native Android app (and iOS). A few other tools are native on Android too — Coordon and AyeDu — while most wedding-day tools (Timeline Genius, Wedding Computer, DayOf) are web-only, and Day of Timeline is iPhone-only with Android listed as coming soon.
Yes. EventSync's Day-Of app reads and writes to a local on-device database, queues your changes, and syncs automatically when the connection returns — on Android and iOS. Conflicting or stale changes can require review; check sync warnings after reconnecting.
Many of the most beautiful venues — barns, mountains, beaches — have poor cell service. An offline-first app keeps your timeline, vendor contacts, and role views working even with no signal, then syncs when you're back online.
A Day-Of cockpit, role-specific boards with caterer dietary details and photographer family readiness, connected team updates, personal section ordering and planner-reviewed SmartRipple recovery included with Day-Of access.
Planning is free with one wedding. Day-Of tools are a one-time Wedding Pass ($49.99), and Pro plans cover unlimited weddings. SmartRipple recovery is free with any Day-Of access.
EventSync's capabilities are verified against its own source code; each other tool's Android, offline, and notification status reflects its public website and app-store listings as of July 15, 2026. EventSync is not the only native-Android wedding app — Coordon and AyeDu ship on Android too — and product details change, so verify before relying on this page.
