Comments on Exposure Assistant for Android

★★★★★ A Google User · Oct 21, 2013

Easy-to-use interface Great way to compare film exposure ratings. Would be awesome to include ektar.

★★★★★ A Google User · Apr 28, 2013

Must-have App for large format shooters! An amazing app for large format shooters who want to accurately calculate shutter speeds due to reciprocity failure. This is the only Android app I was able to find that specializes in these calculations. The developer is also open to suggestions and even added a couple of film types per my request.

★★★★★ Alfred Anheier · May 9, 2022

Very useful for long exposure on film, especially with pinhole cameras. Calculations seem to be good, have to use different films to confirm.

★★☆☆☆ Dagan Sassarini · Jul 1, 2015

Not Impressed I found this app to be inaccurate when shooting Ilford films (Delta 100, Delta 3200, HP5, Pan F Plus). There is no option to choose whether you want to adjust for just exposure time or stops, you must adjust both. So good luck basing your exposure on a particular aperture. The compensations merely follow the graphs provided by the film producer and do not seem to be tested or accurate to my standard. Film selection is few. Research and testing are better methods for dealing with reciprocity.

★☆☆☆☆ Tom Gumpel · Jul 20, 2025

Absolutely garbage. I was shocked to see that there was no trial before paying for this app, and no return option, but decided to try anyway. This is an utter waste of money. The app does not allow one to calculate time based on added filters, nor does it allow for adding fractions of time, such as 1/8...you must first calculate the decimal equivalent. Better to simply use chat gpt. Save your money and refuse to support shoddy work
