Version 1.3.0 has been released to the app store.
iOS4 changed the API that iAutoCalc uses to format the numerical data in the application. This change leads to iAutoCalc malfunctioning when attempting to enter more than 5 digits into any of the fields.
The fix was a simple 1 line code change and the app has been waiting for Apple to review it since June 29th. I apologize to any customers who have downloaded the app onto iOS4 as it is not very useful in its current state.
This situation has been frustrating for me since customers are leaving bad reviews of iAutoCalc, and even though I have fixed the issue I am waiting on Apple to approve the fix and release the fixed version onto the app store.
Thank you for your patience.
