Massive Development Chart iPhone App Review

Almost everyone who develops their own black and white film at home is aware of the Massive Development Chart from Digital Truth. I regularly consult this vast database for development times for the various film / developer combinations I use.

But for the past few months I have added a new tool to my developing kit and that is the Massive Dev Chart iPhone application from Martin Man based on the Digitial Truth database.

The app works on both the iPhone and iPod touch and is real easy to use. First you select your film from the huge list of available films.

Next select the ISO you shot at.

You then choose the developer and concentration you are using.

Once all of that is done you are ready to start developing.

But unlike the web version of the database, this app also provides a timer to ensure correct developing times. Just press the “Start” button and off you go.

In addition to the development time, the timer also has 1 minute of stop time, 5 minutes of fixing and 10 minutes of rinsing. These values can be edited by making the film/developer combination a favorite and then editing that favorite.

What’s real nice about the app is that there is a visual and audible cue for when agitation is required. Just before the end of the minute there is a sound which then changes for the duration of time you need to do the inversions. The font also pulsates during this time.

The amount of time you agitate for is also editable for favorites but from what I can tell there is no way to change the frequency of agitations which is set at every minute. For Rodinal I agitate every 30 seconds so I need to keep an eye on the app when using that developer but that’s not a big deal.

Other nice features include the fact that it keeps on counting even if a call comes in but to stop me being distracted I usually set my iPhone to airplane mode when I am developing. Don’t want to miss the agitation time.

One feature I haven’t used yet is the ability to change the development temperature and the app will work out the time. I also haven’t used the split time feature for developers like Diafine.

The Massive Dev App currently costs $5.99 and in my mind is well worth it. I highly recommend this iPhone app.

The iPhone can be purchased on iTunes.

    I’ve been using the app for over a year now and I love it. There are some features that I would find useful. First, I had to restore my phone a couple of times because Iphone 4.1 gave me some problems. From restoring my Iphone, all the saved, custom times disappeared. Is there a way to store it on the backup? Another feature that would be great is a way to fudge the development time by allowing the adding or subtracting development times. A sliders that ranges from +50% to -50% could be neat. That way, a user can add or subtract percentage of development times by using the slider. Keep up the good work!
