심리 상담 앱을 만들어보고 싶습니다. 코로나 19로 비대면 추세와 우울증 환자의 증가 문제를 완화하기 위해 모바일 심리 상담 어플리케이션의 중요성이 커지고 있다고 생각합니다. 시간적으로 경제적으로 여유가 없어 대면 상담이 부담되거나 고민의 해결책을 스스로 찾기 어려운 분들을 위한 앱입니다. 이미 '트로스트'나 '마인드 카페' 앱이 심리 상담 어플리케이션으로서 상용화되고 있습니다. 주요기능 심리검사 셀프테스트(우울, 불안, 트라우마, 사회적 상호작용 불안 등등..) 마음 정리(감정 일기, 미션수행) 전문가와 상담(1:1 전화상담, 채팅상담) 고민 방(비슷한 고민을 가진 사람들끼리 익명으로 자유롭게 이야기할 수 있는 영역)
