Thanksgiving, dialed in. Host the perfect feast - guests with RSVP and dietary restrictions, turkey timing math (thaw + roast + rest backwards from your dinner time), full menu of mains, sides, drinks and dessert, grocery list by category with a running budget bar, T-7 days prep timeline, table seating with notes, gratitude journal that saves by the year, leftover dish planner, and a Black Friday watchlist with target prices - in one private, offline-first app. Ten tabs. One file. Yours forever for one price. A guest list with RSVP yes/maybe/no, adult and kid head counts, dietary column for vegetarian, gluten-free, allergies and Grandma soft food, plus a notes column for who is bringing what. A turkey calculator: enter the bird weight (auto-recommends pounds based on your confirmed head count at 1.25 lb per person) and your dinner time, and get exact times for when to move the turkey from freezer to fridge to thaw, when it goes in the oven, when it comes out to rest, and when you carve. A menu organized by mains, sides, drinks and dessert with idea / shopping / prepped / done status and cost per dish. A grocery list grouped by category - meat, produce, dairy, pantry, bakery, drinks - each item with quantity, cost and store, plus a live spend bar that goes red when you cross your budget. A prep timeline with day labels (T-7, T-5, T-3, T-2, T-1, Day) pre-loaded with the standard hosting plan: confirm guests, buy turkey, start the thaw, big grocery run, cranberry sauce Tuesday, dry brine Wednesday, prep veggies, set the table, roast Thursday. Tap done on each step. Table & Seating to group people by table (main, adult overflow, kids) with notes for place cards. A Gratitude tab where one line per person at the table gets saved with the year - open it next Thanksgiving to read what you all said. Leftovers planner with five pre-loaded ideas (turkey + cranberry sandwich, stuffing waffles + fried egg, turkey pot pie, mashed potato pancakes, turkey ramen with sweet potato). Black Friday watchlist with target prices, estimated retail and total target savings. Settings for profile, dinner date and time, address, budget, JSON export and import, and full reset. Every input saves locally to your device. Nothing goes to a server. No account, no subscription, no app store, no annual fee. Works on laptop in any browser, and adds to your iPhone or Android home screen as a standalone app for offline use.
