Massive Dev Chart Timer

Great App, Used it for years

And they say temperature extrapolation data is available, but how do you get to it? Great to have the massive chart in digital form, but for $8.99, the app is underbaked.

I’m a commercial photographer who is returning to film for the fun of it. This app takes all the pain and guesswork out of black and white negative development. Hats off and wallets open for the brilliant minds and hard work that made this app a reality!

Lacking several film stocks, doesn’t seem to be a way to add them. Rigid interface, no ability to change or alter development steps or they’re times. Just a bundle of preset timers for $8 was a mistake. Just use the online chart and your clock app, save your money!

The online version of the Massive Dev Chart is very helpful, and I refer to it regularly, so I thought this app would be just as good. Maybe I’ve missed it somewhere in the settings, but I don’t see the option of setting the agitation to “continuous” like you can on the website. The instructions say you can modify your agitation preferences, but none of the options they provide are for “continuous”. Of course I can just deduct 15% from the normal times to achieve this using my free calculator app. But I paid $9 for this app to do that.

The app "crashes" (actually just went to a white screen and then back to the main menu, I never got the iOS crash message) occasionally. The first time this happened during fixing which isn't a big deal, but the second time was during dev and I lost the time, so my final development was off.

Amazing app. Not only does it have all of the dev chart info... you can edit your own times as well. Amazing.

I’ve been using the Massive Dev Chart for over a year. It has worked brilliantly for me. I’m developing mostly Kodak Tmax and Tri-X, but I have also used it to develop Fujifilm Acros I. Just a well thought out easy to use app.

I’ve been using it for years on an old iPad, but when I upgraded to a brand new iPad and loaded the app it crashes EVERY. SINGLE. TIME. It’s unusable. I’ve tried reloading the app 6 times. Still crashes. There is nothing online about this problem other than: “reload the app”. Now I need to keep the old iPad to run just one app - Massive Dev. That’s F’d up.

This has pretty much every type of film/developer I use. It’s an amazing app that makes developing super easy and it allows you to customize and make adjustments as needed. It would be amazing for them to include color film options, especially since c-41 kits are becoming more popular and obtainable for at home developing.
