RoomStack is the simplest way to photograph and catalog everything you own — room by room — so you always know what you have and what it's worth. Built for insurance readiness: if fire, theft, or a flood ever hits, you'll have a complete, valued, photographic record ready to hand your insurer. It's just as useful for moving, estate planning, or peace of mind. PHOTO-FIRST & FAST Snap a photo and the item already exists. Add value, category, brand, and serial number later — or not at all. Fly through a whole room in minutes. ORGANIZED YOUR WAY Property → Room → Item. Start with the ready-made "My Home" and its common rooms, then rename, add, or remove anything. SEE WHAT YOU'RE WORTH One headline total, broken down by property and category. Items you haven't priced are tracked separately so your total stays honest — and one tap walks you through them, saving each value as you go. PRIVATE BY DESIGN Everything stays on your device. No account, no sign-in, nothing collected. Optional iCloud backup & sync keeps a copy in your own private iCloud — only you can see it. An optional Face ID lock keeps the app itself to yourself. ROOMSTACK PRO (one-time purchase) Unlimited items and properties, iCloud backup & sync, and PDF & CSV reports ready to hand an insurer. No subscription.
