I know a lot of people use spreadsheets, but I figure why not take it to the next level? So I'm starting to use a SQLite database with a simple bash CLI front-end for prompting new entries, generating reports, and simplifying some SQL queries. Anytime I find myself dropping down to raw SQL I try to wrap it behind a simple command for the next time.
I want to start adding some REST calls, e.g. to get the current spot price of gold, so I can compare it to my original buy prices.
Good luck with the app, it looks really sleek. And I like how you included a question in your Show HN title to lure me in. :)
