Car Math Pro Car Calculator Customer Insights

1. 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.Payment system is utter rubbish.

2. 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.

3. What this app does best, and what makes it worth the few dollars it costs, is it helps the user make better decisions about which components and settings best meet the user's needs.Some features don't work.

4. It would be a great program if they would take more time and work out the bugs.I'm impressed by the comprehensive data structure and the very full range of calculations possible.

5. Edit, still no reply after 2 emails Edit, I reinstalled version 60.0 and now it works!No experience... I tried about 6 random menu's, an nothing works unless the addtional modules are purchased.

6. For example when putting in compression ratio, the period button doesn't work.

7. Unfortunately the example data is all in non-SI units, and the vehicles listed are very US-centric.

8. It includes an excellent camshaft calculator that renders the cam profile in two types of graphs that can be printed and analyzed.

9. I bought this app to analyze camshaft options for race engines.

10. Emailed last month and got no response.

11. Car Math Pro has exceeded my expectations by leaps and bounds.
