    Dark mode is broken

    In a recent update, when using the app in my dark room to develop sheet film, when I select, dark mode, there is still a bright white dynamic island where the mode selector is, contributing significant light pollution into my space. I’ve had to tape it off with black tape to make it usable. Why did you implement this? Is it a bug?!

  • ★★★★trospero

    Dark mode no longer dark!

    In the darkroom, I rely on the ability to turn the screen of my iPhone to dark mode when using this app to time film development (sheet film, in trays). But in a recent update, there is now a large white “Dynamic Island” where the mode buttons are that cannot be turned dark, so there’s significant light pollution in my workspace when developing film, and I have to put black tape over that part of the screen!! WHY did you implement this?? Is it a bug or a “feature”??!

    Could be so much better

    Timer works fine, that’s the important part. But the UX around the whole app is just bad. It hard to scan the list in My Times (why no search?), can’t bulk delete, can’t sort or group. No separate utilities like the volume mixer. Please take some time to improve the app, there’s so much potential here.

    What gives?

    I don’t know what the bad reviews are about. Honestly, this app has met my every need. I prefer that recipes are pre-programmed instead of having to search randomly for experimental recipes in the other app.

    Put the dilutions back for HC110

    I paid for this because it had dilutions for HC110. It is now removed. If you don’t put the feature back in you owe people a refund.

    No Color film

    Only black and white film

  • ★★★★★bac0nsnatcher

    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.

    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.

    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.
