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?

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.

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.
