I used it for several months but soon found it too limiting. Please bear in mind that what I am going to report is my experience from using it over a year ago, now.
The Massive Dev Chart forces a certain sequence with predefined intervals which can only be truly used for B&W development, and one that follows a "by the book" strategy since it forces a sequence. Once I started experimenting with development by creating agitation patterns I got infuriatingly mad with the darn thing since I could not program different agitation intervals nor different durations for each agitation (I know, everyone has its quirks
). At first I could live with that - after all is just a question of remembering. But then I started also to use multiple stop baths and a specific wash procedure that required multiple water replacements rather than continuous wash. Now the program was completely and utterly useless. Besides, I never agreed with the times it proposed neither did I use the developers it so diligently provided. Started doing everything using a single clock and just being alert during the whole process. When I started fooling around with C-41 and RA-4 I needed a timer. I started looking for timers and found one that kind of suits my needs:
https://itunes.apple.com/us/app/labt...ign-mpt=uo%3D4. On the iphone it only has 4 timers, but are easily configurable. But, on the ipad, it has 4x4=16 timers. YES!!!! Now I could program any sequence that I wanted. It has served me nicely. There are several things I would like it to have, like being able to switch off the screen and block any unwanted screen popup, and the ability to save sequences of timers. While I don't do things by the book, I do like repeatability like anyone else
. The best thing is that labtimer is really free, whereas Intervallo which states in the thread title as being free costs now 1.8€ (probably $2), and can be used on the iphone for long exposures in the field and on the ipad for all chemical endeavours. That luminous screen I really could do without...but then...they weren't thinking of guys like us when they wrote it.
