Ratings and reviews

FANTASTIC! This is something I have wanted for years. I have been having to do all of this by hand with Adams vehicle expense (afr11) logs for years. Only possible change I might do is allow adding the 1/10 position to the odometer but that's a REAL nick pick. GREAT APP, many thanks for creating and providing. Follow up comment: I would like to see an easy way to directly export data directly to a printer. Other than that I'm still loving this app. Many thanks for creating it.

I'm guessing somewhere along the way this app changed from FuelLog Tracker to FillUp. The "older" version that's still on my phone doesn't have the import or export options for the log. I've searched every folder on my phone, and can't find the log and/or data. So, there's no was of transferring almost 3 years worth of data from the old app to the new one, or to a dropbox/google drive account. If I hadn't attempted to download the log from a recent trip, I wouldn't have known about this change!

I'd give it a 5th star if it had just a couple more options that I'd personally like to see. 1. a way to check mileage over a custom range, and the ability to compare it to another custom range. 2. If the mileage falls outside of a set percentage deviation from the average, an alert.. example if your average is 25 mpg, and suddenly your mpg is 20 it changes the background of the calculator or the text in the log to red.
