▶ What is our app?
DOIF is a fasting timer and routine recorder app that helps you easily and consistently maintain intermittent fasting (fasting time). You can set up representative plans like 16:8, 18:6, 20:4, and OMAD, manage fasting start and end times in one place, and organize your routine neatly with records and statistics.

DOIF is not an app that forces you to endure fasting through willpower. Rather, it automates your routine with time, notifications, and records to foster consistency.

▶ Health/Medical Notice (Not a Medical Device / Not Medical Advice)
DOIF is not a medical device and does not provide diagnosis, treatment, prescriptions, or prevention. The information, notifications, and statistics in the app are for general lifestyle management purposes and are not a substitute for professional medical advice. Always consult a doctor or specialist before making any health-related decisions.

▶ Immediate Stop and Emergency Help Recommendations (Caution Signs)
If you experience any of the following symptoms while fasting, stop fasting and seek immediate medical help if necessary. - Fainting/decreased consciousness, severe dizziness, weakness to the point of difficulty walking
- Severe palpitations/chest pain, shortness of breath
- Symptoms of hypoglycemia such as confusion, cold sweats, tremors, extreme hunger, and inability to concentrate
- Persistent vomiting/severe dehydration
- If you are pregnant, breastfeeding, have an underlying condition, or are taking medication (especially diabetes medication/insulin), we recommend consulting a professional before fasting.
