Life By Synheart
Life is for people whose output is their attention. It detects changes in your focus, fatigue, and cognitive load — from how you type and interact, plus an optional wearable — and helps you answer the question that actually matters: deep work now, or rest?
Free, on-device, forever · Reads how you type, never what
Two signals
Life’s behavioral input. It reads the rhythm of how you type — pace, pauses, corrections — and turns it into a live read on focus and load. Never the words. Never the content.
Connect a watch or ring and Life adds the body’s side of the story: heart rate, HRV, recovery. No wearable? Behavioral signals alone are enough to start.
What you see
Life turns signal into a daily picture: where your focus went, when load climbed, how recovered you arrived. Every reading reports change with a confidence value not a verdict so you know when to trust it.
74
How steady your attention is. Life watches how often you switch apps, how often you are interrupted, and the rhythm of your typing.
31
How much load your body is carrying. Life reads your heart rate and the small changes between beats.
62
How ready you are today. Life compares last night’s sleep and your resting heart rate against your own normal.
