Great app, thank you!

Road Trip is one of the few apps I actually like and use. I don't like to remember or know much at all about my transportation appliances, but I need the info to manage and make decisions about them. Road Trip gathers and presents all that info for me apparently without sniffing my every move, weight gain, utterance, and networks of friends, families, and associates, etc.

I had an idea for the app. I can already see the complexity of implementing it, but figured I'd share anyway. For statistics, you provide a total cost to date summary. I would love to see an inflation adjusted total cost to date summary as well. E.g. I bought a used car in Jan 2015 for $11,500 USD, which now* has an inflation adjusted value of about $13,719 USD. in order to normalize the values before summarizing, the app would have to consider for each entry the purchase date, report date, currency, etc. as well as refer to consumer price indexes such as those behind the US BLS CPI Inflation Calculator.

This would give me a clear understanding of total cost of ownership in today's currency. When looking at that $3000 repair estimate on my current car vs. scrapping it and buying a replacement car, I could then compare costs in an "apples to apples" manner to support my decision.

*or as close to "now" as is possible to estimate based on available reference data, which is plenty close enough.

Hidden gem you need to get for your car

I have been using this app since at least 2010. It has helped me track expenses across a number of cars past and present. There are numerous great feature that will help you understand what it is costing you to own your vehicle (if you are willing to track it). It has shown me a down downgrade in fuel economy outside of traffic patterns which lead to a tune up. Having your expenses recorded, especially when you have 4+ actively driven vehicles, can be helpful as to when the next service should be performed (oil/brakes/brake fluid/radiator fluid/etc). Amazing how fast you forget when something was installed, like wiper blades. I highly recommend this app and hope you will get as much out of this as I have. Thanks to the developer for keeping this relevant and useful.

LOVE this app!

I was using another app for a while until it stopped being supported. Found this app as a replacement and it has nearly every option I wanted. It’s beautifully crafted, fairly intuitive, has a bunch of graphs, reminders, and features that are well worth the investment. I stay on top of my MPG and have access to historical work so I can save time with my mechanic. It allows multiple cars, syncs automatically to iCloud, and the tabs get me to where I need to go quickly. No “subscription” nonsense and the app is kept up to date.

There are a few areas where I’d like to see the developer bump up the GUI and perhaps also add some explanation and/or help screens. But the core of this program is solid and it’s one of the few apps I would install if I only had a 4GB iphone. It’s a keeper.
