Tired of Task Management Bloat?

Modern productivity tools have become part of the problem.

Account Required

Create an account, verify email, set up a workspace, invite teammates... just to make a simple to-do list.

Your Data on Their Servers

Task lists, project names, client details - all stored on someone else's infrastructure, often used for "product improvement."

Subscription Fatigue

Free tier runs out. Features get locked. Prices increase. Another $10/month added to the stack.

Offline? Good Luck

On a plane, in a cafe with spotty WiFi, or just somewhere with no signal - your tasks become inaccessible.

Feature Overload

AI assistants, integrations, automations, calendars - sometimes you just need columns and tasks.

Vendor Lock-in

Exporting your data means navigating settings, requesting downloads, and hoping the format is usable.

Why I Built This

A thesis on software that works everywhere, for everyone.

I kept noticing a pattern: employees discover great tools, but can't use them at work. Enterprise approval processes exist for good reasons—protecting company data is serious business. But the friction means useful software sits in approval limbo while people muddle through with worse alternatives.

Then I had a thought: what if the approval process had nothing to review?

If there are no servers, no data connections, no vendor database—if everything runs locally in the browser and the user controls where data lives—then trust is inherent. There's nothing external to question.

This app is designed around this principle. It's not just offline-capable; it's offline by design . No network calls. No analytics. No telemetry. The file sits on your computer, does exactly what you expect, and nothing else.

I call this category Automatically Approved Tools —software that enterprises can adopt instantly because it's safe by design, and that users love because it's thoughtfully crafted.

No IT ticket required.
