Heymoon's new name: Happy Monday

Happy Monday uses your personal records to accurately predict your period, ovulation, and fertile period. Customize your notifications to ensure you're prepared for ovulation, starting 7 days, 3 days, or 1 day before your period.

If your partner installs the Happy Monday Connect app, you can check your menstrual cycle without having to ask. It also provides easy access to women's health information to help you be more considerate.

앱에서 월경을 기록하고 위생용품을 구매할 수 있는 것과 '해피문데이'로 이름을 바꾸는 것은 만족스럽지만, 앱의 새로운 버전에 파란색 색감이 개인적으로 별로다. 전 색 팔레트가 부드러운 느낌도 있었고 보기 편했는데, 새로운 버전의 파란색은 볼 때마다 너무 쨍하고 월경앱엔 맞지 않다고 느낀다.

안녕하세요. 솔직한 의견 남겨주셔서 감사드립니다. 헤이문 서비스를 잘 사용해주신 만큼, 새 색상이 다소 낯설게 느껴지셨다는 점 충분히 공감합니다. 이번 업데이트에는 월경 기간에도 나답게 잘 지내보자는 응원과 에너지를 표현하고자 했습니다. 보내주신 소중한 의견은 내부 팀 모두와 공유하며, 더 나은 서비스를 위한 중요한 참고로 삼겠습니다. 해피문데이는 '월경을 중심으로 여성이 건강을 이해하고 증진할 수 있도록 지원한다'는 서비스 목표로 최선을 다하겠습니다. 감사합니다.
