About

Dométric

Read full description

Dométric is a private domain portfolio manager for investors and indie founders who want clear numbers — not another browser tab. WHAT YOU CAN DO • Add and organize domains with purchase price, fees, renewals, registrar, category and status • See portfolio value, cost basis, ROI, held / sold / expired / abandoned at a glance • Track renewals with overdue vs due-soon views and in-app renew flow • Record sales with live preview of cost basis, fees, net proceeds and profit • Analyze sales, marketplace fees and TLD / category performance • Import and export CSV; backup and restore on-device • Appraise a name offline with market-anchored retail, wholesale and listing hints (quality score always free to preview) BUILT FOR ACCURACY Cost basis is consistent across screens: purchase + transfer + expenses + renewals paid. Sold P/L uses the same fee math as Record Sale. Exports and shares match what you see in the app. PRIVACY-FIRST Your portfolio stays on your device. Dométric does not sync your domain list to a Dométric server. WHO IT’S FOR Domain investors, brandable flippers and builders who need a mobile source of truth for cost, renewals and exits. NOTES Appraisal is an offline heuristic anchored to public aftermarket patterns — not a live broker appraisal or guarantee of sale price. Currency display uses your chosen symbol (no live FX conversion).
