Holsi-호르몬 시스터즈

Your Personal Hormone Sister

Track your cycle, get AI-powered advice, and care for your hormones — all in one app. Partner mode now available!

Holsi isn't a complicated medical app. Think of her as your closest friend who nags you when you're struggling with PMS, reminds you to take your supplements, and looks out for your mental and physical health every day.

Cycle Tracking Log your period with one tap. Holsi predicts your next date, ovulation window, and cycle phases — and gets smarter the more you log.

AI Advice (Holsi's Take) Get personalized daily advice based on where you are in your cycle. Holsi speaks your language — no medical jargon, just real talk.

Supplement Reminders Add your vitamins and supplements and set custom daily reminders. Never miss iron on period day again.

Partner Mode Connect with your partner so they can see your cycle status and understand what you're going through. Care starts with understanding.

AI Image Import (OCR) Already tracking somewhere else? Take a screenshot of your old records and Holsi reads the dates automatically.

Cycle Insights After a few cycles, Holsi shows you your patterns — average cycle length, PMS trends, symptom history, and more.

Backup & Restore Your data is safely synced to the cloud. Switch phones without losing a single record.
