## Massive Dev Chart Timer Reviews in United States

### **--- "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, this app 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 this app to anyone due to it's limitations. In this app, 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.
-- CreativelyJeff, 2025-01-07

### ***** "Thank you"
Great App, Used it for years
-- Oly XA, 2024-12-21

### ***-- "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, the app is underbaked.
-- Mills Center Contemporary Music, 2024-10-06

### ***** "I love this app!"
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!
-- tpf1952, 2024-04-21

### **--- "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!
-- gh3tt0o3m0n5, 2024-03-12

### **--- "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 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.
-- bassman94, 2022-12-24

### *---- "Crashed during dev twice"
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.
-- Tyler Menezes, 2022-05-19

### ***** "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.
-- cfwheezy, 2022-01-11

### ***** "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.
-- Yankee Dog57, 2021-07-15

### *---- "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 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.
-- GeMuHofman, 2021-04-13

### ***** "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.
-- Lenscratch, 2019-05-21

### ***-- "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.
-- 52 Cameras, 2019-05-10

### *---- "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.
-- Leftclicktailwag, 2019-01-27

### ****- "PLEASE FIX!"
Love the app! 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!!!!
-- IanHurdle, 2018-12-08

### ****- "Cool but wish it was customizable"
So I bought this to develop my first roll of Ilford HP5+ and while it was super helpful I had to write a couple notes to myself where I altered your events such as the hypo clear step. Could you please let us edit the titles or even let us add our own operations?
-- p8blr, 2018-11-19

### *---- "Black and white only"
No where does it state its black and white only. Completely useless to me.
-- Timbertimbre, 2018-07-04

### ***-- "Latest upgrade broke on iPhone 4S"
I’ve been using this app 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 the app 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.) The app 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.
-- Earlrond, 2018-05-21

### ****- "Great app"
Awesome and invaluable. I wished the alarms rang when I'm on another app like YouTube though...
-- DocTranimal, 2018-04-09

### ***** "The best!!"
I’ve been using this app for years. This is THE BEST app out there if you’re going to be working in the darkroom. Couldn’t recommend this app more.
-- Ashesinthefall, 2018-01-17

### ***** "Great database! Especially for beginners"
This app has been great! It takes all the documentation that used to be printed and bundles it all up into a nice app.  I've only been developing for a couple years but this app has been a great tool for me.  I still have my binder of documentation from the vendors I use, but for quick references and timer, it's great!!!

The only thing I wish was on the app, was pull times.  I know everyone pushes but it be nice to have pull times as well.
