What are the best free mental health apps for depression?

6th Mind is a free mental health app using AVE therapy developed from clinical practice experience. Our sessions are based on protocols used with real patients. No ads, no subscription required. The app is a complement to professional care, not a replacement.

How does AVE therapy work in a mobile app?

The app delivers synchronized light and sound through your phone: light from the camera flash or, in headset mode, from the screen held close to your eyes in a simple 3D-printed headset that fills your whole visual field. Sessions work with eyes closed or open, are 6 or 11 minutes long, and AI-optimized: built around a data model from our practice office. A daily Wellbeing score from about a minute of your voice shows what helps you, and once you have enough checks, your routine is built around it.

How long does it take to see results?

Individual responses vary. Some users report initial improvements after 1-2 weeks of regular use. Most benefits typically appear after consistent daily use for 4-6 weeks. This is a complementary tool - seek professional help if symptoms persist.

What people are telling us

“After losing access to roXiva at my local float spa, I tried several at-home apps. 6th Mind has been the best and the closest to that experience. In just a few sessions I'm already seeing the same kind of improvement.”

“The sessions had an extremely strong effect on the quality of my sleep, improved how I handled difficult situations in daily life, and lifted my mood. Overall, I'm extremely satisfied and was sad when they ended.”

“The sessions had a fantastic effect that lasted for months afterward. The session itself is very pleasant and relaxing. Highly recommend!”

“Thank you for giving back to the community. I've tested many audio-visual entrainment products, and yours is a breath of fresh air.”

Immediate benefits

With 6th Mind you can ease stress and anxiety in minutes. You fall asleep faster and sleep deeper, without medication. Your mood lifts naturally, helping you feel focused and energized. Everything happens safely and non-invasively. All you need is your phone.

Personalized for you

Your journey begins with a quick questionnaire, and the app builds a 15-day plan from your answers. Each day, about a minute of your voice gives you a Wellbeing score, so you can see how you're doing and what helps. Once you have enough daily checks, 6th Mind builds your routine around the sessions and frequency profiles that work best for you. After day 15, a second questionnaire shows what changed and shapes your next plan.

6th Mind My activity: Wellbeing score 59, improving by 2.6 points a week

The science behind your calm

6th Mind uses light pulses and sound tones to guide your brain into balance. The method is based on psychology and neuroscience, refined over 1000+ sessions with 170 people in our practice office. The app learns from your Wellbeing scores and refines your routine step by step. No extra devices are needed: the light comes from your phone's camera flash or, in headset mode, from its screen, eyes closed or open. Headphones can deepen the effect, but they are optional.

Go deeper with headset mode

Headset mode turns your phone's screen into a full-field light source: the display splits in two, one half per eye, with colours tuned to each brain state. All it takes is a simple 3D-printed holder, making 6th Mind the most affordable audio-visual entrainment system you can own, and the most advanced one that runs on hardware you already have.
