Automatic $$ Charge

This app showed up as free on the App Store, I did not accept any in-app purchases and was charged $20. I don’t even have an OBD yet I just wanted to check the app out- and upon looking it’s too complicated for me and I prefer the dealership. I need a refund as I never accepted to buy this or saw the price just got a receipt in e-mail which I’ve requested Apple to refund. It just charged me same-day but many hours after I downloaded the app.

This tool paid for itself the day it arrived.

This tool paid for itself the day it arrived. I disabled the backup warning (it had to go) and low speed warning noises. The tire pressure monitor (TPM) is very helpful. It took about 15 mins to get the TPM assigned to the correct corner once I understood the GUI. The assigning process could be much more simple, but it does work fine. I like having the live data from the TPMs. Very useful battery monitoring tools that take some time to understand the data your getting. I found some of the change options under the service screen (if used incorrectly) detriment. The warnings are there and would recommend users heed them or at least proceed with carefully.

Use it all the time, but.....

This is a great app and I use it just about every time I drive my car.

The but is.......I moved to a new area with varied terrain and seasonal temperatures. The miles/kWh isn’t as accurate as I would like when discovering new routes to my destinations. I think it’s because the kWh units are too small (the degraded battery in my 2011 holds less than 14kWh. Instead, I think a GIDs/Mile feature would allow better assessment of various routes, and sections of routes, as I have 200+- of those when starting out. Perhaps a real-time GIDs/Mile reading as well as an average reading would be helpful.

Anyway, thanks for the great app!
