I got tired of tracking my yoyo collection in a spreadsheet, so I built an app for it (free, open source)
Once I got past a hundred yoyos the spreadsheet fell apart — there were too many columns, photos were clunky as hell, the “for sale” tab was in some spy code that I don’t remember writing. So I made a web app instead. You can browse as tiles or a list, search and filter, add photos and zoom in, track specs, keep a separate For Sale page, share a single yoyo as its own page or save an image of it to send to someone, import/export CSV, and download full backups.
There’s a demo if you want to click around (no signup): test.daveronica.com. Password demo gets you the editing view, and it’s read-only so you can’t break anything.
It’s free and open source if you’d rather host your own:
Happy to hear what’s confusing or missing.
If there is a desire to see it fully used I can share mine. Just don’t want to break any rules.
