As do I. However, a light meter with an ongoing monthly cost of US $70 (even if it's a shared cost) doesn't appear to me to be one of the best bargains out there, and that outlay is required before one can use the app. Obviously individual folks will decide for themselves about that, and the apps are selling.

Your point of view is about as distorted as a Petzval.

To say that someone is using an iPhone, and/or would buy an iPhone solely as a light meter is asinine.

However, down here on earth, folks such as myself who got rid of their home phone, and use an iPhone as a cell phone, home phone, work phone, merchant services card processor, portfolio, email client, mileage tracker, gps navigator, weather forecaster, traffic checker, music player, address book, and social network connector..... why not enjoy the use of a handy light meter.
