What if your thoughts didn’t run the show?

  • A person sitting at a green table, reading a book with a cup of coffee and potted plant nearby.

    Make decisions without spiralling

  • Illustration of a woman sitting on a yellow beanbag, holding a mug of coffee or tea, with bread and cookies on the floor in front, and a plant in a pot beside her.

    Switch off without guilt

  • Illustration of a man with glasses sitting on a yellow chair, holding a steaming mug in one hand and a saucer in the other, at a yellow table.

    Feel confident, even in uncertainty

A different kind of mental health app.

Most apps give you tips you won’t stick to. Luma gently shifts your habits, one small practice at a time.

It’s not about being perfect. It’s about feeling better - in a way that works for you.

  • "When exhausted by anxiety, the advice is often as overwhelming in itself, and just makes me feel it will be impossible to try so this makes so much sense and makes me feel able to try it without added stress"

    Rachel

  • "I believe it is encouraging to see that other people struggle with the same or similar issues. I believe it is important to let others know they are not alone in this. This very thought can help. Thank you for your work."

  • “I just noticed this morning that my WorryTree app morphed into Luma overnight. I also noticed my favourite features are there, plus some new ones I look forward to reviewing. I will continue to share news of Luma with all the helping professionals I work with, and of course my friends and family.”

Meet Luma.

A beautifully simple mobile app designed for overthinkers, by overthinkers.

Just a few minutes a day.

Grounded in real therapy.

Designed to work.

Mobile app screen titled 'Wellbeing & Balance' with weather feeling options: Sunny, Cloudy, Rainy, Stormy, Windy, each with a circular selection icon. Below is a text box for reasons for feelings, and a green 'Save' button at the bottom.

Built by someone who’s been there

Luma was built by Louise, who was diagnosed with generalised anxiety disorder and found CBT genuinely life-changing - but inaccessible outside of a therapist’s office.

She built Luma so that the tools that helped her could help other people too.
