Gas Log is the simple way to track fuel costs, fuel economy, and everything else your vehicles cost you. Log a fill-up in seconds and let the app handle the math. **Track unlimited vehicles.** Add as many vehicles as you need โ€” each with its own photo, color tag, VIN, and full history so you can tell them apart at a glance. **Automatic MPG and cost calculations.** Enter your odometer reading, gallons pumped, and total cost โ€” Gas Log instantly calculates your MPG, cost per gallon, and cost per mile. No spreadsheets, no manual math. **A real Stats dashboard.** See your MPG trend over time, a full cost breakdown, and exactly where your money goes by category โ€” filterable to the last 3 months, 6 months, this year, or all time. **Track expenses beyond fuel.** Maintenance, insurance, registration, tolls, parking โ€” log it all and see it broken down alongside your fuel costs. **Partial fill-ups supported.** Didn't fill the tank all the way? Log it as a partial fill-up and Gas Log keeps your MPG calculations accurate. **Full fill-up and expense history.** Every entry โ€” date, location, gallons, cost, odometer, category โ€” saved and easy to review. **Import and export your data.** Bring in your existing fuel and expense records via CSV, or export everything anytime, right from Settings. **Your data stays on your device.** No account required. No data collection. No ads. Gas Log is completely private โ€” everything is stored locally on your device. **Made for everyday drivers.** Whether you're tracking one car or managing costs across a small fleet, Gas Log keeps it simple. --- Download Gas Log and start tracking every mile and every dollar. ---

This screenshot shows the text fields empty and โ€” check this โ€” "0 of 10 Screenshots." Your 8 iPhone shots showed as uploaded earlier; either this view is a different device-size well (scroll up to check the iPhone 6.3" section still shows 8), or they didn't persist. Verify before anything else โ€” and after uploading media or filling fields, hit Save (top right) before navigating away; this console loses unsaved work. Here's everything paste-ready for the fields on this page: Promotional Text: Free, private, offline. See how many days your household could last and what to stock next. Widgets, outage mode, and go-bag checklists included. Description: PrepTracker helps your household stay quietly ready for power cuts, storms, and everyday disruptions. It is free, it works fully offline, and your data stays on your phone. No account. No ads. No tracking. SEE YOUR RUNWAY Log the water, food, and supplies you already have. PrepTracker shows how many days your household could last, what runs out first, and the next thing worth adding. Targets scale to your household, including kids and pets. BE READY FOR OUTAGES The power runway estimates how long your batteries and power stations can carry the essentials. When the power goes out, Outage Mode puts food safety timers, a flashlight, and your plan on one calm screen, with a Live Activity countdown on your Lock Screen. GO-BAGS THAT BUILD THEMSELVES Start from ready-made templates for a 72-hour bag, car kit, kids' bag, pet bag, and documents pouch, then check items off as you pack. Your readiness score updates as you go. KEEP THE IMPORTANT THINGS CLOSE Store emergency contacts, medical cards, and evacuation routes. Lock sensitive notes in a vault protected by Face ID. Add widgets to your Home Screen and Lock Screen so your runway is always one glance away. PRIVATE BY DESIGN Everything lives on your device. There is no login, no cloud account, and nothing to sync. If you choose the optional weekly email digest, your device sends only a short summary you can read before it goes. CALM, NOT ALARMING PrepTracker is built for ordinary households, not bunkers. Regional starter packs suggest sensible supplies for where you live, and the app nudges you toward small, steady progress. PrepTracker offers general preparedness guidance only, not professional emergency advice. In an emergency, follow instructions from local authorities. A product of Cubed Holdings LLC.
