Well for someone who is interested and needs something like this.
My experience so far with Milebug is that it is a fantastic app for the small business owner that needs to track his miles. It has made my consistency in tracking my miles for both my businesses and personal use a no-brainer. You can keep adding presets until anything you repeat takes a couple of taps to add to the log when you are on the go. It's a fantastically useful app!!!!!
It was a great buy at $2.99. I see they just updated the program and raised the full unlimited app to $6.99, and introduced a MileBug Lite for $2.99 that is limited to logging 10 trips at a time with the ability to save the 10 trips (send an email report in Excel or Word readable form) before resetting to 0.
I am not sure I care for this strategy. It would be better to have a Lite version that was free and didn't allow you to save, so you could just test drive the program (or say 4 Trip limit with ability to save so you could see how that worked) and see if you liked it. If you busy running your business and are bad about tracking your miles and constantly struggle to remember to write down or find yourself trying to reconstruct the week, you want the full $6.99 version for sure. It will be worth it.
If you are in the corporate world with the same issues, you might like Trip Cubby which is $9.99, especially if your company will reimburse you for it. Also it's report being a csv attachment to an email is better idea than what MileBug does which asks you to cut and paste out of the body of the email into Excel (hasn't worked for me so far so while I have the reports safely saved they are not in working spreadsheet yet). I think MileBug has better interface and it's cheaper, but Trip Cubby looks a bit more comprehensive for those putting in monthly expense reports as opposed to those like me that simply need to track it for the IRS schedule C.
If you are looking for something more than a mileage logger, you might consider XpenseTracker that allows you to track and report all your expenses including logging miles. I have it as well and like it though I use MileBug for everyday mileage tracking. Unfortunately, I see that they just jacked it up to $12.99 from the price I paid for it. It's great app, and if you need it worth it. I just wished developers wouldn't get greedy.
