A Urination Diary is a convenient app for tracking urination frequency and volume, fluid intake, and overall hydration balance. It’s designed for people with urological conditions, pregnant women, athletes, and anyone who wants to monitor their health. You can enter data manually or collect it automatically using compatible devices. The app analyzes your data, highlights potential irregularities, and helps you track trends over time. Flexible reports make it easy to share information with your doctor for evaluation and treatment adjustments. Reminders help you stay consistent with logging, while the intuitive interface keeps everything simple and clear. The app does not require any external devices to function — they are optional and can be used to simplify data entry (for example, by automatically transferring readings). This app is not a medical device and is not intended for diagnosis, treatment, or prevention of diseases. All information provided is for reference purposes only and does not replace professional medical advice.
