I wanted to introduce an app which I developed in the last few weeks. It is called LFTools. In LFTools you can calculate several Bellows functions, like extended exposure time in regard to bellows extension or the bellows draw from a given magnification and more. It also has a film reciprocity calculator and a database where you can edit/add/delete your own films. The database comes pre-populated with Ilford films. AFAIK Iford is the only manufacture who publishes the p factor. If there are others let me know, I will then add those to the DB. You can install the iOS app (v1.5) from the app store. It is free!
Parallel I developed the Android app. Unfortunately Google changed the rules for Indy developers, so that it does not make sense to me to develop it any further. The Android version is 1.0 and available on Aptoide under Beta versions. If you have no problems with side-loading you can get it there. Compared to the iOS version it has only the extended exposure time bellows function. But contains the film reciprocity calculator and editor.
If you are interested check it out. Should you find any errors please let me know, thanks.
