Wedding Planner – Offline Budget, Guest List & Seating App

What you get

Plan the whole wedding in one place: budget, guests, replies, seating, checklist and the day itself. Wedding Planner is a complete app in one HTML file. It opens in your browser, works offline and keeps your data private on your own device – no subscription, no account, no formulas to break.

Every item has an estimate, an agreed price and its payments, and you get an alert as soon as an item, a category or the total goes over budget.
