Frequently Asked Questions
Everything you need to know about Fluen AI
A bladder diary, also called a voiding diary, records when you pee, how much, what you drink and any symptoms such as urgency or leaks. Urologists often ask for one before an appointment. Fluen keeps it for you and turns it into a PDF report you can share with your doctor.
Yes. Alongside bladder visits and water intake, you can log bowel movements with the Bristol Stool Scale (types 1 to 7) and stool color, so your bladder and bowel diary lives in one place.
Fluen uses advanced microphone audio analysis to automatically detect and log urination events, completely hands-free. The analysis happens entirely on-device for full privacy. No audio is ever recorded or stored.
Absolutely. All processing happens on-device using Apple's frameworks. Your data is synced privately via iCloud CloudKit, so only you can access it. We never see, sell, or share your health information.
