Great app Simple and effective Please add Tri X 320 Thanks                     Roberto Romano

Excellent and Indispensable App Rollei Retro 400s a really nice Still Life film appears to function identical to RPX 400                     Spehmaster G.

Great to the point interface I love that it has timer as well I have yet to try how accurate the estimated values are but this will surely help a lot                     Matias Autio

Great app Please update more film profiles thxs                     prokopis v

Great application saves all the hassles in the field when calculating the right exposure Certainly worth it I would appriciate a bigger clock timer and perhaps the possibility to correct the calculated exposure time based on a personal experience But all in all good and it does the job                 Zdenek Lukas

Does what it says on the tin Lightweight Perfect Please add Ektar 100 Edit and he did what a legend Stand by my five star rating                     Kenny McCartney

Great app and fantastic to finally have Kodak Ektar included                     Michael Mercer

No more jotting down tables in my shooting notebook                 Very useful app Tim Lowe

Superb thank you                     M Lewis

This is the only Android app for reciprocity failure calculation available on line Very useful for old fashioned film photographers There are so many barriers I have to over come to buy and download this app from where I live but this app worth it                     Very good Zhe Xu

This is a great tool for us film shooters Finally I can get rid of my manual sheets                     Life saver thank you Pali K

Great app and even greater support from Matt I recommend it highly Saves much time in estimating exposure time from film manufacturers data sheet                     Fantastic exposure calculator for film Tim Halloran

Saves a lot of faffing doubly so now the time is presented in minutes on long exposures New timer should prove very useful to save swapping between apps in the field                     Excellent Steven McGregor

This will help immensly calculating long exposure guesswork                     Great idea John Meyer

Great way to compare film exposure ratings Would be awesome to include ektar                     Easy to use interface Stephen Migol

What a simply top app Didn t think I d be able to find an app like this and there it is Easy to use Simple with no unnecessary frills                     Great app David Clarke

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                     Must have App for large format shooters Neil Ta

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 or not 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         Not Impressed Dagan Sassarini
