Garage Reorder (G4R) is garage order tracking for your whole fleet — cars, trucks, motorcycles, boats and jet skis, even e-bikes. Track replacement items, reorder, and build a permanent on-device record of every part you order, install, and service. Add a vehicle and G4R starts it with the four most commonly forgotten replacements: windshield wipers, key fob battery, cabin air filter, and engine air filter. Add your own categories — brake pads, spark plugs, anything your vehicle needs — each with its own replacement interval. YOUR FLEET AT A GLANCE • Overdue, due soon, and on-order counts the moment you open the app • Color-coded status for every item and vehicle • Track as much as you want per vehicle: VIN or serial number, license plate, insurance policy and expiration, warranty coverage REORDER IN ONE TAP • Every item carries an Amazon search link matched to your vehicle's year, make, and model • Track the whole order: link opened, ordered, delivered, installed • Marking an item installed resets its replacement countdown automatically A RUNNING RECORD OF YOUR GARAGE • Order history per vehicle and per item — every install is saved with its dates, product, and your notes • Service records with who did the work: a shop, the dealership, the oil-change place, the auto parts store, or you • Export order history and service records as print-ready PDF tables (AirPrint supported) • Rate parts on cost and quality in your notes — they're saved with each record REMINDERS AND INSTALL HELP • Local notifications when a replacement comes due • Install videos, owner's-manual searches, and step-by-step resources per item • Attach photos to vehicles and items PRIVATE BY DESIGN • Sign in with Apple or Google — no separate password to manage • All data stays on your device; no server account, no analytics, no tracking • Optional Face ID protection The free Regular plan supports up to 3 vehicles and 6 items per vehicle. As an Amazon Associate, 4DAT LLC earns from qualifying purchases made through links in the app. G4R does not display Amazon prices, ratings, or reviews, and search links are not fitment guarantees — always confirm part fitment for your specific vehicle before ordering.
