Offline mode

Restaurants are not always blessed with reliable connectivity — basements, corner seats and rooftops all conspire to drop the signal. The DineOS mobile app is local-first: reads come from a local replica, and writes go into a queue that replays when the network returns.

What works offline

• Viewing today's reservations and the floor plan.
• Marking a guest as seated, completed, or no-show.
• Adding free-form notes to a reservation.
• Scanning a voucher (the redemption is queued and applied on reconnect).
• Clocking in and out.

What needs to be online

• Searching the global guest CRM beyond today's bookings.
• Talking to the AI assistant.
• Sending an SMS or email confirmation immediately.
• Stripe-backed actions (refunds, payouts).

Conflict resolution

When the queue replays, conflicts are resolved automatically:

• Status changes use last-writer-wins. The status that was set most recently — by clock time across all devices — sticks.
• Notes are merged. Both users' additions are preserved with author and timestamp.
• Table assignments defer to the server-side authoritative state and surface a yellow banner to the user whose change was rejected.
