ADHD Clock
Time made visible, calm, and structured.
Free visual timer for ADHD and time blindness
This ADHD timer makes time visible instead of abstract. Rather than showing a number counting down, a shrinking ring lets you see at a glance how much time remains — no mental math, no guessing. It's designed specifically for the way ADHD brains experience time: either "now" or "not now," with nothing reliable in between.
What is time blindness?
Time blindness is a well-documented challenge common in ADHD — the inability to sense how much time has passed or accurately estimate how long a task will take. A standard digital clock showing "14:37" doesn't help, because the number requires mental processing. A visual timer that shrinks as time passes gives your brain a concrete, immediate signal it can actually use.
How to use this timer for focus sessions
Start with 10 or 15 minutes — short enough to feel manageable, long enough to make real progress. Type one task in the box. Press Start. The ring handles the rest. When it ends, take the break the timer offers — skipping breaks leads to burnout, and the break is part of why the system works. The +2 min and +5 min buttons are there for when you're in flow and need a little more time without stopping to reset.
Why no ticking?
Ticking sounds are grounding for some people and actively distracting for others — particularly for those with sensory sensitivities common in ADHD and autism. This timer produces no ticking at any point. The only sounds are the optional gentle chime at completion and the soft tone on zone transitions, both of which can be turned off entirely in Settings.
