About

G4R

Features
Read full description

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.

The call

The clearest difference is update cadence: G4R at every 4 days against Sensors Toolbox's every 5 months. Sensors Toolbox's advantage is iOS requirement (12.0 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.
