Your to-do list
is lying to you.

It treats every task the same — whether it's been waiting 5 minutes or 5 weeks. 4hoy reveals the truth with Task Debt, a visual system that shows the real cost of waiting.

Every undone task
is a debt you carry

The longer a task waits, the more it weighs on you. 4hoy makes this invisible weight visible. Tasks shift from calm green to urgent red as they age — so you always know what's been waiting the longest.

No more guessing. No more forgetting. Just honest, color-coded truth about your productivity.
