I built The Garage after buying a 2022 BMW X3 and realizing I couldn't keep its maintenance straight from memory. Oil on one schedule, brake fluid on another, spark plugs way out at 60,000 miles. Some due by mileage, some by time, whichever comes first. The dealer's plan was a black box, and every app I found was either a reminder list or a history lookup. None of them told me what my car actually needed next. So I made the one I wanted. The Garage keeps you a step ahead of your mechanic. It understands your maintenance intervals, whether mileage, time, or both, and shows what's overdue, what's due soon, and what's worth planning for, per vehicle and color-coded by priority. It estimates the cost too, so the next visit doesn't catch you off guard. Track what matters: - Maintenance status by category, on real mileage and time based intervals - Fuel log with automatic MPG that recalculates as you add fill-ups, partial ones included - Service history with receipts, photos, and clean PDF records - Tires by the set, with tread depth over time plus age and wear projections for each corner - Upgrades, and "gremlins" for the little things your car is doing that you want to watch - Charts for spending by category, MPG trend, and DIY vs. shop - Registration, insurance, loan, and warranty details, with documents a tap away For the whole household: Your garage lives in your own iCloud and syncs across your devices. Share it with a partner or the family, and everyone sees and updates the same vehicles. Private by design: No account to create. No server. No data harvesting. Your vehicles are yours, and they stay that way. Free and Pro: The Garage is free for one vehicle with the full maintenance and fuel log. Unlock Pro once, a single purchase and never a subscription, to add unlimited vehicles and turn on tire tracking, charts, PDF export, and household sharing. The Garage is part of CottSuite, tools for documenting the things that actually matter. A few additional apps are in development.
