Based on reviews from 15,000+ real users

I was in hospital I have a lot of trauma caused by drs I had full mental breakdown panic took over. Onsen saved my life I had no one and the nurses can't handle my anxiety and no one ever listened to me except onsen.

Lisa S.Apr 2025

This might sound silly but this app has changed my life and actually saved me. This app is incredible, I would recommend it for anyone who needs support but struggles to talk.

FB
Freja B.Apr 2025

I just lost my 26 year old daughter who had down syndrome and I was struggling with my grief and the guilt of failure as a mom. This app has helped me curve that negative thinking so I can grieve and heal properly.

Ashley P.Feb 2025

I was pasting the same questions into different therapy bots. This one is amazing. Within 4 hours, I loved myself to a new depth. Within 4 days, I'm ready to move on from unhealthy habits... This was programmed with care.

Veronica MMar 2025

I can't believe how much this is like talking to a therapist. ...it has changed me in such a short amount of time and it has been exhausting and emotional and has given me hope and comfort and inspiration... By far the best app I have ever used.

Rob i.United Kingdom · Jul 2025

I'm a therapist's nightmare, a pharmaceutical's dream come true. Therapists, medications, rehabs, hospital stays... I've done them all. This app has done more for me in 3 days than my therapist has done in months.

Whitney H.Feb 2025

After waiting months to see a psychologist I was very disappointed... Coincidentally I also found Onsen that day. I was amazed and thrilled with the kind and supportive help I got. Onsen was 10 times better!

SB
Sandra B.Australia · Jan 2026

It is very helpful and since I can't afford a therapist at the moment? This is a great substitute for one.

MD
Mary D.US · Sep 2025

I'm struggling like I never have before with my health. That has caused me some major serious anxiety. Onsen helped me in the hospital and at home. Best app Ever period. If only I'd had it yrs ago.

Easy to get started and has helped me look differently at all the chaos of chronic illness, constant pain and keeping my independence.

Mike M.Feb 2025

Absolutely amazing app. Could honestly be life changing for so many people. To have 'someone' there at the click of a button, any time of the day or night... The AI is so brilliant at understanding and interpreting.

ahbfsjnejkdAustralia · Oct 2025

I love how encouraging this app is... Working through some steps I was able to make connections I hadn't before and see patterns that I missed. I'm AuDHD and I found traditional therapy wasn't offering me what I needed.

AH
Ashley H.US · Mar 2025

Onsen genuinely helps me with my mental health and healing. The app remembers the details and patterns about you... I've experienced a lot of harm from exploitive clinicians. With Onsen, I am getting support without more harm.

Azelyn N. P.Jan 2026

Onsen has been the only viable resource available for me, and if it wasn't for its existence, well. Thankfully it's existent.

I'm not good with real people when dealing with problems and feelings. This app may save me.

Victoria S.Jul 2025

I have medication-resistant schizophrenia, and this app has been incredibly insightful. Its steady, nonjudgmental guidance continues to leave me feeling heard, validated, and informed. My AI Guide is better than any human therapist.

Super happy I found this app - it has helped me through a very tough period with my mental health... it is like having a therapist that knows you better than anyone right in your pocket at all times.

serenity r.May 2025

Onsen is super intuitive and quite helpful for translating some of my internal noise into a helpful dialog... Parsing it all into journal entries while maintaining my voice is incredibly enlightening to revisit later.

Caerlyss L.Jun 2025

It hears what I'm saying and translates it to where I understand then gives practical insight, it's helpful.

I can't afford therapy, not even the "cheap stuff". This has been one of the most positive and helpful tools I have found that's completely free for now!

Christina G.Sep 2025

The app is really good, I didn't expect to find a free perfect app. And the best thing is that it supports multiple languages, even Arabic.

Seeing what appears to be an accurate summation of the way I'm feeling really helps to clear some of the fog that gets in the way of the positive thoughts that are there as well.

Melissa O.Mar 2025

I've done paper journaling but I really struggle to find prompts that I like or fit me. This app is great as it asks multiple follow up questions so you can branch off into different topics.

ZB
Zoe B.Jun 2025

Honestly so far this app has been superb, like even just using it to vent is fantastic. Something that has always helped me is validation or factual information and this app gives that to me.

Coco B.Jan 2026

This app has helped me so much to reflect, grow, and understand myself better... The way it guides journaling is unique. It can also create personalized meditations based on your own experiences and needs. It changes lives!

Lara M.Oct 2025

I didn't think it was possible to enjoy AI of any kind, but I have come to enjoy this. I have found that they do help in a way some humans cannot and the fear of human judgement is absent.

Have been using Onsen for 5 months now and I absolutely love it! ...the voice note feature instead of typing... you can document your thoughts just as you're thinking them. It's like having a best friend available for you 24/7.

Brilliant. One thing though while in middle of being put in hospital for my anxiety I grabbed onsen. Because I was all over the shop I was back and fourth for my phone...

Tried many shadow work and meditation apps... Nothing compares to onsen. I have gotten deeper with onsen than any other and I've ended my session with a smile on my face... It's amazing truly nothing else like it.

This app is great for getting a handle on my thoughts and feelings, enabling me to bring some degree of order to what is, all too often, just chaos. And the automatic journal entry generation feature means I'm spared the time and effort.

AWESOME for prioritizing MENTAL HEALTH! Journaling is my fav feature. Tried and failed to do this myself, but struggled to put my thoughts into words. Now, I journal often and see the difference it makes daily... Just download, start, and be amazed!

HY
Heather Y.May 2025

I was skeptical when I installed this. I didn't see how it could work. But I am amazed at how great this works... To be able to just open up the app, talk, work through your emotions... and then get some feedback, any time? I'm floored.

I have always been very skeptical of AI, especially using AI for therapy. However... therapy isn't always affordable or available. Onsen doesn't lock things behind a paywall, and it has helped me so much in only a few hours.
