I made a HC-110 Helper App (Free and Ad-Free)

Hi All,

if you're like me and use HC-110 for almost anything, you might be interested in this:

Over the past days I made a little web application to help with Kodak HC-110 mixing and developing. The app runs on my website (and can run on your smartphone - both IOS and Android within a host app).

My design principle was to essentially provide an interactive digital version of the peel-off bottle label that comes with the developer. The app calculates HC-110 specific temperature time conversion for given combinations based on an exponential function which has proven to be very accurate in my tests and based on that calculates rough push/pull values in relation to temperature as well that should get you into the ballpark if you don´t have your own values yet. A third neat little feature I added is a mixing calculator that shows all dilutions at a glance with a dynamic slider for the amount of working solution (plus capacity).

If you want to try the app you can do so here on my website where you can download it too. The app is free, ad free, and as far as I can say does not collect any personal data whatsoever. I developed it for my own use but figured I could as well share it. If you use the app it´s important to use only HC-110 that was mixed with distilled water as water hardness can mess massively with HC110 and thus the times calculated.

Nice. I haven't been using HC-110 recently, but I still have some of the old syrup -- which is supposed to be the same (in terms of dilution and time/temp activity) as the new.

Thanks for sharing!

This is way cool! HC-110 is the developer I chose to start myself off with, and I think I've finally gotten the hang of it. This will be extremely helpful in avoiding having to look up temperature conversion charts!
