Train your attention. Quiet your mind. Take back control of your focus. Built around the Attention Training Technique (ATT), this app provides a structured way to practise attention training and develop greater control over where your focus goes. Through guided exercises, you learn to shift attention deliberately rather than becoming stuck in worries, distractions, overthinking or repetitive thoughts. Originally developed as part of metacognitive approaches to mental wellbeing, ATT helps strengthen attentional flexibility by training you to move, sustain and broaden your focus. Regular practice can help you become less caught up in rumination and more able to direct your attention intentionally. Whether you’re looking to improve concentration, reduce overthinking, or build greater control over your attention, Attention Training: ATT Timer provides a simple and practical way to practise.
