Ratings and reviews

I'm impressed by the comprehensive data structure and the very full range of calculations possible. Unfortunately the example data is all in non-SI units, and the vehicles listed are very US-centric. I would give this 5 stars (or even more if that were possible) if the units could be chosen on initial setup and consistently maintained, and if the example data was left out so as to avoid making assumptions about how the user wants to utilize the app.

Some features don't work. For example when putting in compression ratio, the period button doesn't work. Instead of 9.1:1, you can only enter 9:1, or 8.5:1, you can only enter 8:1. It would be a great program if they would take more time and work out the bugs.

Payment system is utter rubbish. I already bought lots of modules in november last year to find they no longer worked this year, bought all modules again last month and now it says I need to buy them for a third time. Emailed last month and got no response. App is very useful but let down in this way. Such a same. Edit, still no reply after 2 emails Edit, I reinstalled version 60.0 and now it works!
