Vision Reference is provided completely free of charge and without adverts. I currently make a loss each year from Apple's fees which are required to keep the app available on the App Store. If you'd like to support the ongoing development and upkeep of this app, please consider leaving a donation.

Special thanks to Crispin Cooper for programming support, Michael Thomas for loan of equipment, and Jon Parkes for beta testing. The iOS version implements the TSAlertView class, by Tom Swift.
