A phone case milled from solid pine and set with firm natural bristles — engineered to make idle scrolling quietly unpleasant, and intentional use entirely possible.
The average adult reaches for a smartphone well over a hundred times a day — most of it automatic, none of it chosen. Software-based limits fail because they ask the same compromised attention that created the habit to police it. Bristle relocates the intervention to the hand.
5h+The typical daily smartphone screen time for an adult user, a figure that has climbed steadily for a decade.
tactileBristle introduces a small, unavoidable physical cost to prolonged holding — present at every idle reach, absent the moment a task is purposeful.
The case for Bristle rests on a maturing body of randomised trial evidence. Two findings are foundational.
In a randomised controlled trial, students who reduced smartphone use to two hours or less daily for three weeks showed small-to-medium improvements in depressive symptoms, stress, sleep quality, and well-being — with the authors concluding the relationship is causal rather than correlational.
When 467 adults blocked mobile internet access for two weeks, more than ninety percent improved on at least one measure of mental health, well-being, or attention — with sustained-attention gains comparable to undoing roughly ten years of age-related decline. Participants redirected the freed time toward people, exercise, and time outdoors.
These are independent peer-reviewed studies of screen-time reduction in general; they do not evaluate this product. Bristle is a wellbeing aid, not a medical device, and makes no clinical claims. Both trials note limitations including self-selection and modest sample sizes.
Designed to protect the device fully while making the act of holding it a decision rather than a default.
A precision-milled solid pine back, sealed with a food-safe natural oil. Warm to the hand, quietly beautiful, and renewable by definition.
A dense field of stiff agave-and-sisal bristle, machine-tufted in the manner of a fine brush. Firm enough to deter the resting palm; never sharp.
A recycled TPU inner shell with raised camera and screen lips. Full drop protection — the friction is for you, not the phone.
