About this app

Your mental gym. Open daily.

ReThink is mental fitness for your mind. Like going to the gym, but for the way you think. Built on cognitive behavioural therapy (CBT), the most researched form of therapy, turned into a daily practice you can do on your own terms.

How it works:

You create scenarios based on real situations in your life, the things that trigger unhelpful thinking. For each scenario, you add negative thoughts (the patterns you want to push away) and realistic thoughts (the perspectives you want to pull in). Then you train: push down the negative, pull in the realistic. Repeat. Over time, the realistic response becomes more automatic.

The coach can help. A short conversation that builds a scenario with you, so you don't have to start from a blank page.

This isn't relaxation. It's training. Cognitive restructuring is a procedural skill. It gets stronger with repetition, like any skill.

What you get:

- Sessions of 1, 5, or 10 minutes. Even a quick one counts
- A coach that helps you build scenarios through conversation
- Progress tracking: reaction time, accuracy, mood trends
- Scenario assessments tracking distress, interference, and confidence
- Works fully offline. Train anywhere, sync when you're back
- End-to-end encryption for your personal data
- Available in 10 languages
- No streaks, no guilt. Just a practice worth showing up for

Who it's for:

Everyone. Not just people in crisis. ReThink is for anyone who wants to catch unhelpful thinking patterns before they spiral, whether you're managing everyday stress, working through something specific, or building mental resilience alongside therapy.

A complement to professional care, not a replacement. Something that works alongside therapy, before it, after it, and for the millions who'll never reach it.

Empowerment, not dependency. Mental fitness, not relaxation. Better minds. Better lives. Better world.
Your mental gym. Build a stronger mind with science-backed daily practice.
