4 apps, one standard

Small apps that do the heavy work.

Small enough to open in a second. Heavy enough for half a million rows. No ads, no accounts, no tracking — and everything you make exports.

The standard

Different jobs, same three rules.

Fast on real data

Not demo data. A 500,000-row CSV opens on a phone, scrolls without stutter, and sorts without a spinner. If it can't hold up on the real file, it doesn't ship.

Honest about what's free

No ads, no accounts, no analytics, no upsell theatre. What you make stays on your device — nothing is uploaded, synced, or read by anything.

Nothing gets trapped

PDF, PNG, Markdown, OPML, CSV, plain text. Importing is always free, so a backup taken today still opens on another device years from now.

The catalogue

Four apps, so far.

Each one started as a file that wouldn't open, a note that wouldn't stay put, or a habit that wouldn't stick.

Found a rough edge? Tell me about it.

One person builds these, and every bug report lands in the same inbox. Feature requests too — plenty of what shipped started as an email from someone using the app on a file I'd never have thought to test.
