Happy user since 2012!

I bought Road Trip on October 9, 2012. Nearly 11 years ago, and I’ve entered nearly every fill-up since, across multiple cars! I realized it’s so ingrained in my habits I neglected to rate and review, sorry for the delay! I also thought maybe I’d be unique in my longevity with the app, but I quickly saw another review from 2009! My purchase (I found my receipt!) was of version 1.8.1, and the App Store only has history listed back to version 11.3 now, 7 years back!

So, this app is awesome. Pretty much works perfectly, calculates all the stats you might want, backs up to Dropbox silently without fuss, is easy to enter data in, has numerous flexible options to customize the availed fields for each car and tracking preferences. Just absolutely amazing. Thanks to everyone else still buying this app because it’s provided a lot of value for the one-time purchase 11 years ago, and still gets regular updates and bug fixes.

Major thanks to Darren for making something so solid and useful! I’m sure he doesn’t even know who I am, as I’ve never needed to contact support or interact to get everything working.

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.

I love this app!

I have used Road Trip since January 2009! I track every ounce of fuel in put in every vehicle I own, it even keeps the data for vehicles I’ve sold if I choose not to delete them. The charts swipe to show instantly how I’m doing for my selected or custom time range, I even use the charts and date ranges to show price changes over time to people who don’t believe policies don’t have consequences. But seriously, this app really helps me manage my budget related to costs for fuel, repairs and maintenance. My business would be a lot harder without it.

The only thing I’d like to see is a way to compare numbers by gas station; is this station better than another? Is my mileage better with this gas vs that gas? Do I spend more money at a particular station over another each week/month/year?, etc. That would be great!
