This app was disappointing. So much is missing. A safe light for starters. And then, where is the timer for stop bath and fixed as advertised. I had a much better timer before my phone died. Unfortunately, that timer isn't in Apple apps anymore. One star for an over priced and aDisappointing app.
Exactly the title and nothing more
Channing l martinez
This app is for exactly what the title says and nothing more... it’s only a timer for the developer part of film processing, it will find a time for you the most films and most developers but it is not a full development process timer it will not stop and change to the next process which is the stop bath. It’s pretty good but some of the icons used are not really explained, you kind of have to tested out to see which icon means what... for example there is one icon that supposed to be represent a push poll process how much do you want to push your development and pull it...it was a test to figure out that’s what the icon was for.

Needs help.

I’d seen Massive before but bought this one to try. If you want to put in your film and developer and push start, that won’t be happening. If you JUST want time for the developer, that can be done fairly quickly. However, even after adding the other timers (stop, fix, etc) I could never figure out how to start them. Additionally, I changed screens on my phone to look up the dev time to make sure it was right, and when I came back the timer was now —:— even though it should have had about 4 min left. I think this one could be good with more work.
