I’m super excited to try this out, it is feature packed and looks intuitive. The main problem I have is that it’s a bit dated, iOS 14 vs current iOS 18 and the support for cheaper, off the shelf Bluetooth probe thermometers (ThermoPro) is nonexistent.

This app has the capability to be a great app for roasting if they update it. If you have a Behmor 1600 and only use single origins your good. I can only inventory my single origin beans, wouldn't let me list my blends that are from multiple origins. So far this is a waste of $10

Except for coffee! And like the full suite of Office, I only use about 5% of what’s offered! I log inventory, roast times (nose, eyes, ears mainly) but overall, a useful tool for a roaster business. If there were just one item I’d like added, it would be the development percentage added to the roast screen! My mental math, converting the mins/secs to hit 25-30% DT is just too much every roast! Since dev time is a percentage function, why not add it?!?
