"Bia changed my life. It gives you small steps to take every day and tracks your progress. I'm not done, but I already feel so much better and am doing so much more."

App Store Review

"I can tell this was built my someone who had phobia. They get it. The app lets you customize and take a little placement quiz. You can pause or exit whenever and it's very careful and explains every step. Thank you for making this"

App Store Review

"In short, this site is brilliant. The best help you will ever get apart from an in-person specialist, bar none."

Dr. David Russ, Clinical Psychologist

"I feel extremely optimistic using this app and have already changed the way I think and feel more confident in stressful situations as I know what to do . It's also great that your mental health professionals can connect to your account and also have tools provided to them to help them help us."

App Store Review

"It starts with theory foundations and basic exposures and works you up an exposure hierarchy, helping you acclimate and build confidence."

App Store Review

"I love how the exposures are slow and very incremental. It's felt like what I imagine exposure therapy with a therapist would be like! The check ins are helpful and they really help me keep an eye on my anxiety levels while working on the exposures. I also appreciate the reminders to slow down! I'm only on chapter 3 but I'm feeling very optimistic"

William Schaller, Founder

I Believe You Can Recover

Hello, my name is Willy, founder of Bia. I suffered from emetophobia for most of my life and know first hand the misery and loneliness it can cause. During my recovery I built a tool to track my progress and help me practice. Over four years this tool transformed into Bia, now used by people around the world. I'm happy to share I have recovered from phobia and I believe you can too.

Elizabeth Fullerton, Co-Founder

From Bia User to Co-Founder

My name is Elizabeth, and I am Co-Founder of Bia. I came across an early version of Bia while working through my own phobia recovery and became one of its first users. I was already seeing a therapist, but once I added daily guided-exposure practice with Bia the impact on my recovery was immediate. I've since partnered with Willy to leverage my health-care background to build and expand Bia, and it's been incredibly meaningful to see the tool help others just as it helped me.
