      Science Behind Sigh

      Friction

      Cognitive Behavioural Therapy

      Awareness

      Psychological Flexibility

      Vaping is often automatic. Many puffs happen without conscious thought. Sigh creates moments of friction by locking the device when limits are reached, interrupting the cue-routine-reward cycle and giving the brain time to make a deliberate choice.
      The science: Habit Loop Theory, Behavioural Economics, Response Inhibition.

      Hollie is a registered osteopath with a Graduate Diploma in Psychology and a passion for behaviour change. Working closely with patients gave her a deep appreciation for how stress, emotions, and habit loops shape people's behaviours. After seeing how many young adults had become unintentionally dependent on vaping, often wanting to quit but lacking the right tools and support, she co-founded Sigh to create a more human, science-led approach that helps people understand cravings, break automatic habits, and regain control.

      The puff counter has made me so aware of how much I vape. It definitely will help me reduce my vaping habit.

      It doesn't make me feel guilty for vaping. It just helps me understand it better and gives me practical tools to change.

      I noticed how much I vape after a meal. That's where I use most of my puffs.

      How does Sigh work?

      Sigh connects your vape to your phone and tracks every puff in real time. You choose a reduction plan that suits your goals, and your daily puff allowance gradually decreases over time, ultimately reaching zero. When you reach your daily limit, your vape temporarily locks, creating a pause between craving and action. Throughout the journey, guided exercises help you understand your triggers, build awareness around your habits, and develop the skills needed to manage cravings and quit for good.
