Sourdough starter app

Hi all,

I'm making a device at university that creates the perfect conditions for sourdough starters. This device also connects to a mobile application. I'm just curious and looking for some good insights in regard to what information would be useful to be shown through the mobile app and what sort of things you would want to know? Is there any specific information about your sourdough starter that you would want to be shown/notified about?

Thanks

Harry
