1. It's just a calculator you put stuff in and you get numbers out.The app will not open, sends an error messagethey make you do all the guesswork instead of putting in car and engine info and the to/fromWhen i first use this app.
2. First time downloaded and it said some account was suspended right when I opened it for the very first time.
3. And again I got the app but the very first time today and have never owned the app before.
4. It looks like their license for some of the software went bad.
5. I don't even see how an account would even be relevant to this type of app.
6. It was simple and eazy to use and understand.
