For the curious and for a bit more information as to what it is/does...
Essentially it's just like spreadsheets like what other people use, but easier to use for a phone environment. It doesn't connect to the internet at all, all the data is stored locally and offline (which isn't much data, what you put in for blends amounts to a few KB because it's just text data).
It's essentially just a cellar tracking app, like having a list of all your blends, but one that you can search, filter and sort quickly and easily. At the moment, included fields are just: brand, blend, type (broad genre category), "quantity" (a simple, generic, whole-number value which you can just decide for yourself what a quantity of "1" represents, like is that 1 tin, 1 gram/oz, etc), very simple personal ratings (favorite, neutral or dislike), and notes. All fields are filterable so you can see say, only the blends you have from C&D, or only the blends you have from Sutliff that are also aromatics and in your favorites, etc.
That's the main purpose, a filterable list of what you have, not to dissimilar to how people that use spreadsheets use their spreadsheets. The main page also has a table view mode if you prefer a table to a list, and eventually if I can figure out how to make the bottom app bar disappear on scroll, you'll have a lot more screen real estate in landscape orientation. The table also is sortable by clicking the columns at the top for brand or blend (alphabetically sorting ascending, descending, and then the default sort order of the order in which you added things to the database).
Adding stuff is pretty easy, it only requires filling out the brand and blend fields, all others remaining blank (though leaving the quantity field blank, it presumes the quantity is 1). The brand field in adding also has an autocomplete suggestions that pop up based on what you already have in your database. Text enterable fields in the future will also have this if it's a type of field where you might be entering the same data a lot.
There's also a stats page that also reacts to the filtering, with several pie charts for visualization.
It also has a function for importing a CSV file, so if you have a spreadsheet, you can export the spreadsheet as a CSV and then import it to the database without having to manually enter in everything. There's an import wizard that allows you to map the CSV columns to the correct columns in the database table. It also has an option to export CSV files too, so if you want to keep spreadsheets on the computer or keep the list backed-up, you can easily do that.
In the future, I plan to expand on this with additional fields like in- vs out-of-production status, subgenres, components, cut, purchase/manufacturing and open dates. I also plan to expand the options, like default list sort order, CSV import options for updating missing fields in existing entries, overwriting chosen fields for existing blends, etc. I am also considering adding a pipe database for saving your pipe collection with stats for that and fields for various parameters (like bowl and chamber diameters, height, length, finish, stem material, etc). I'll also extend layout support to tablets (taking advantage of the larger screens).
It will never have ads, or track your personal information, or device information, and it will always be free, and requires no special permissions.
Some things it will never do involve anything that requires internet connection or connection to existing tobacco websites (due to Android policies about tobacco and the facilitation of its purchase).
I made a quick video to showcase what it's current capabilities are. In the video when I demonstrate the note entry, you may notice the first line get duplicated... that's not a bug that you'll ever see unless you are, like me, using a very out-dated keyboard (even then, you only see it because I'm being way more rapid in entering than anyone would be actually typing a note):
