Fluen is a bladder and bowel health diary for iPhone and Apple Watch, also on Mac and Vision Pro. Log visits, drinks and symptoms in seconds and bring a clear report to your doctor. For overactive bladder, incontinence, interstitial cystitis, UTIs, BPH, or simply drinking enough.
WHAT YOU CAN TRACK
- Bladder visits: volume, urine color (8 shades), duration and time of day
- Bowel movements: Bristol Stool Scale types 1 to 7 and 8 stool colors
- Drinks: 9 beverage types, with temperature
- Symptoms: urgency, pain, burning, incomplete emptying, frequency, nocturia, hesitancy, weak stream, leakage and blood in urine
LOG IN ONE TAP
- Quick Pee and Quick Water right on the Dashboard
- Widgets, Siri, Shortcuts, Control Center and the Action Button
- Auto Pee: keep your iPhone nearby and Fluen times your flow, then estimates the volume from your own learned flow rate. No audio is recorded or kept.
- Flo noticed: Fluen learns your usual times and suggests a log when one looks missing
APPLE WATCH
Log from your wrist, speak to log, and ask Flo a question.
FLO, YOUR AI HEALTH COMPANION
Ask about your patterns or prepare questions for your doctor. Apple Intelligence answers on your device. With Gemini in the cloud, Flo can also read a photo, search the web and remember what matters. Fluen asks before anything leaves your device.
SMART REMINDERS
Nudges timed from your own logs: a drink when you tend to forget, a visit before your usual time, an evening cutoff for better nights.
SHARE WITH YOUR DOCTOR
Keep your providers in one place and create a PDF report of your bladder diary with charts, ready for your urologist, gynecologist or GP.
FAMILY PROFILES AND SHARING
A separate diary for each person you care for. Link accounts with a partner, parent or child to follow each other's logs, sharing only what you choose, and stop at any time.
HYDRATION
Set a daily fluid goal. Fluen reads water and steps from Apple Health to tune it.
PRIVACY FIRST
Your records sync privately to your own account. No ads, no tracking. Available in 18 languages.
