Massive Dev Chart Timer

A very comprehensive database of film/dev combos and has a great processing timer. If on iOS you can further tweak agitation schemes and other defaults in the settings area. All in all, it has been well worth whatever I paid several years ago. Yes, info can be had for free online but this still costs less than a roll of Double-X. A must-have if you like to try different film stocks and developers. I recently souped film for the first time in a few years and used three film/dev combos and was able to just go into MDV and use it again with zero futzing about - very intuitive. A must have!

Very useful app, but would be nice if we could re-label some of the processes such as an additional wash instead of Fixer B.

A box of 4x5 film costs $30-$70. The chemicals cost even more. You’re investing time and money and care into getting this right. If this app cost me $40 it’d be worth it stamp out the expensive risk of getting mixtures wrong.

It’s a great app, until it jumped from 8.99 to 11.99. Now it’s like yea, it’d better be good.

With new upgrade looks much better on my ipad. Thank you! Very easy to use. Being able to easily add films and developer combos and to he able to edit items just adds to the already very functional app. this app helps developing my films easier and hence adds to my enjoyment of photography

This is an incredibly useful tool for any dark room enthusiast. That said, it needs the ability to compensate for constant agitation and temperature differences.

Digitaltruth is a great place for those who like to keep the spirit of analog photography alive. This app is well worth the money and updates keep improving!

I was hesitant to spend the money on this app initially since I could get the development info for free online. But this was one of the most useful and best designed apps I've ever bought. Being able to customize all of the steps and times for my development style is great. It is so easy to use and well laid out to make film development easy.

Unbelievable, that this app exist ! This is amazingly well written by someone who know what processing film is all about. Well done.

I've used this app for processing 35mm and super-8 film. The timer is easy to use and customizable. The temperature/time conversion calculator is really handy. I've customized profiles for hand processing super-8 films. Saving those profiles and add notes makes it much easier to track your process and results.
