3.8 out of 5
No Color film

Only black and white film

Crashed during dev twice

MassiveDevChartTimer "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.

Black and white only

No where does it state its black and white only. Completely useless to me.

Way different on iPad

No film or developer combos like on the iPhone app. Safelight mode doesn't work on the iPad, big WHITE banner that displays template name over the "safelight" mode display, which makes "safelight" mode is worthless.

Great app on Android/iPhone but extremely disappointing on iPad.

Great app - when it doesn’t crash

I’ve been using it for years on an old iPad, but when I upgraded to a brand new iPad and loaded MassiveDevChartTimer it crashes EVERY. SINGLE. TIME. It’s unusable. I’ve tried reloading MassiveDevChartTimer 6 times. Still crashes. There is nothing online about this problem other than: “reload MassiveDevChartTimer ”.

Now I need to keep the old iPad to run just one app - Massive Dev. That’s F’d up.

Just use the online chart and your clock app, save your money!

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!

Not worth the price

Dear App Developer, it would be fantastic if we could create our own timer instead of being limited to a set of developers based on the film I choose and a general configuration based on my preferences. However, MassiveDevChartTimer is only for black-and-white film stock development, and doesn't help with color film (C41, E6, ECN2 and other) development. Regrettably, I wouldn’t recommend MassiveDevChartTimer to anyone due to it's limitations. In MassiveDevChartTimer, you can only make minor adjustments to saved “favorite” processes, which is practically useless for many seeking to develope at home. I would like to see a development timer that allows me to add or remove a few stops from my development time. This tool is not worth the $8.99 USD I paid for. I’ve switched to another app which has most of my requested features called “Develop!” and it's FREE!!! Hopefully you can improve this application.

Dilutions are no longer on the chart

Dilutions used to be more clear and simple to pull up. The latest update is hopefully just a mistake as it now forces you to manually add them yourself to each mix.

May have wasted my money on this

The online version of the Massive Dev Chart is very helpful, and I refer to it regularly, so I thought MassiveDevChartTimer 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 MassiveDevChartTimer to do that.

Love the web site - the app not so much.

Can't give "My times" steps meaningful titles - if your work flow deviates at all, it can't be saved in a useful way. Notes don't word wrap so you can see them. An app this mature should at least be aware of new sentences - auto capitalization is built in to the OS. I do enough traditional processing to probably keep it but pretty sad for 9 bucks.

How do you convert temperature to F.?

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, MassiveDevChartTimer is underbaked.

Latest upgrade broke on iPhone 4S

I’ve been using MassiveDevChartTimer for quite some time, and must say it is very useful when I develop black and white film, and I rather like it. However the latest upgrade broke on my iPhone 4S despite the fact that the phone is running iOS 9.3.5, which MassiveDevChartTimer is supposed to run on. The problem is that UI elements tend to overlap on the screen, making some parameters impossible to change. (Example: trying to turn on time-temperature conversions changes the temperature setting! I tried using a stylus instead of my finger but it didn’t do any good.) MassiveDevChartTimer works fine on my iPhone 6S+, but as that is my primary phone I’d rather not expose it to chemicals - that’s what I use the old 4S for. Guess I won’t have a choice until the problem is fixed in a future update.

Could I make another suggestion? Please allow different agitation regimens for developing and fixing.

PLEASE FIX!

Love MassiveDevChartTimer ! BUT. Please fix the home screen line (located at the bottom of the screen on iPhone XS) while in darkroom mode. It is emitting a bright light during development. I’m having to duct tape over it at the moment. Thank you!!!!

Surprisingly good

Despite the negative reviews and the somewhat steep $9 price tag, I went ahead and bought MassiveDevChartTimer. So far, I'm loving it. Will it ever replace all the other real timers on your darkroom? Of course not. But it's awesome for anyone like me who forgets if it's been three and a half minutes since I started or four and half minutes. Also, you can customize every development scheme to a pretty good extent, which means I can even use it for developing color film too!

I gave it four stars because it's not the prettiest app in the store and because of the price tag (though, it's still one of the cheapest things you can buy for the darkroom these days).

I love this app!

I’m a commercial photographer who is returning to film for the fun of it. MassiveDevChartTimer 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 MassiveDevChartTimer a reality!

Excellent App

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.

EXACTLY what I was looking for

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

The best!!

I’ve been using MassiveDevChartTimer for years. This is THE BEST app out there if you’re going to be working in the darkroom. Couldn’t recommend MassiveDevChartTimer more.

Thank you

Great App, Used it for years

Truly amazing

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.
