Coffee Grind

Sadly, the app does not go past the 1st step where the coin size is selected on either my Samsung phone or tablet. Whether I select one of the pre-defined coins or enter my own coin size value, clicking on continue does nothing. The slider does not seem to do anything either. The app looks very well designed, so I was pretty disappointed.

This is the best particle size analysis app for Android that I've found. Being able to set your reference object size manually is fantastic! The detailed analysis plot is great too. Its so incredibly refreshing to find a useful app that doesn't require account creation. Bravo! If I could improve anything, I would add some +/- fine tune buttons to the contrast and reference object sliders (fat fingers!).

Part of analysing the grind includes selecting the grinder you are using. Unfortunately the list is sadly out of date as I have a Timemore C3s Max and it only lists the G1 and C2 models. I went back in to search for my other grinder (Kingrinder) and I can't access the settings. Whilst you can manually select a coin diameter it has a drop down list and there are no UK sterling coins listed. Very much needs a refresh and update of options.
