About

Deadline Zero

Features
Read full description

Deadlines aren't numbers on a calendar. They're gravity. Deadline Zero shows your tasks falling through space. The closer the deadline, the lower they sink. Miss it, and they fall into the abyss. No complex systems. No overwhelming features. Just your tasks, falling. HOW IT WORKS - Add a task with a deadline - Watch it descend as time runs out - Complete it before it's consumed - Or let it fall—and learn from it THE ABYSS Missed deadlines don't disappear. They collect in the abyss below. You can recover them, but you'll see exactly how many times you've let things slip. The app remembers. The question is whether you'll do better. FEATURES - Visual deadline system—tasks fall as time passes - Free positioning—drag tasks anywhere on screen - Urgency indicators—color shifts as deadlines approach - Task details—add optional notes for context - History tracking—see saved and fallen tasks - Import/Export—backup and restore your data - Dark interface—no distractions, just focus DESIGN PHILOSOPHY Most task apps add features. Deadline Zero removes them. What remains is pressure—the good kind. The kind that makes you act. No notifications begging for attention. No gamification. No streaks. Just a simple question every time you open the app: what's about to fall? Built for people who need to feel their deadlines, not just see them.
