Problem

The number of GLP-1 weight-loss medication users (Wegovy, Mounjaro, etc.) is surging, but there's no systematic way to log side effects like nausea, vomiting, and constipation — so patients report vaguely at appointments ('my stomach was a bit off yesterday'). Doctors can't obtain the side effect frequency, severity, and pattern data needed for dosage adjustments, leading to conservative prescribing and unnecessarily prolonged dose escalation periods (averaging 2–4 extra weeks).

Solution

Users log daily side effects in under 1 minute (symptom type, severity 1–10, linked to meals and exercise). The app auto-generates weekly trend charts by dosage period and a visit-ready summary report for their doctor. Reports can be shared via KakaoTalk or QR code, and dose escalation timing recommendation alerts are also provided.

Target: Adults age 20–50 currently taking GLP-1 weight-loss medications (especially self-pay patients), obesity clinic physicians
Revenue Model: Premium Subscription: basic logging free; visit reports + trend analysis + dose escalation alerts at $3.70/month (4,900 KRW). Obesity clinic B2B license at $74/month per clinic (99,000 KRW, unlimited patients).
