Would love your feedback – I made a tea & coffee app for tracking brews, harvests, and recipes

Hey all,
I’m an indie iOS developer and longtime brew enthusiast, and I just released a new app called Kōtei. It’s designed to help folks track their favorite coffees and teas — with features like custom recipes, a steep timer, and even a monthly calendar of tea harvest seasons.
It’s still early days, but I’d love to hear what this community thinks — especially from those working in coffee/tea professionally.
What kind of features do you find useful when logging brews or experimenting with extractions?
I’m planning to work on a physical notebook companion coming later this year, for those who prefer to jot things down offline too.
Here’s the link if you’re curious:

Thanks in advance for your thoughts! :folded_hands:
