I use this all the time

Love this app. I’ve used it probably a thousand times over the years.

Needs a rework of the new version

I was an early adopter of this app, and it has been a godsend. I used it on my iPad in max mode and it was great. Just downloaded the update and the timer bars are tiny and there is so much blank screen going to waste it just doesn't make sense.
Also if you try and create new times from the dev chart, you can select your film, your chemistry, but when you select the film speed the app just crashes.
Not an improvement overall, this is a great tool, but this version needs to be checked and sent out again with bugs fixed and a bigger timer section. Once that's done, I'm sure it will be better than ever.

Brilliant App

This is a great app and with the included timer, cuts down equipment needed to process bw film. Surprised to read negative comments asking about colour and Portra film, these are C41 process and the time is always the same regardless of film, so not much of a database needed. I have been using this data since it first appeared on a Palm handheld, and it has never let me down, I teach photography and always suggest it to students. Worth every penny.
