Fluen AI: Bladder Health Diary
Pee & Water Log, Doctor Share
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
New in 2.3: share your bladder and water logs with your doctor and choose exactly what they see. Log a pee or a drink in one tap and watch your daily cup fill.
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.

What's New in Version 2.3
Fluen 2.3 brings your doctor into the picture.
NEW
- Doctor sharing: link your doctor to one profile and choose exactly what they see: bladder logs, water intake, bowel movements. Add them by scanning their code, searching their username or typing a code. Sharing lasts up to 12 months, and you can renew or stop it at any time.
- Visits and reports: keep a record of your visits with a linked doctor and send them one of your saved PDF reports. Only that doctor can open it, and it is deleted when sharing stops.
- For doctors: choose how you will use Fluen during setup and get your own workspace for patients and requests, with a Doctor ID and QR code to share.
- Your daily cup holds your whole day: it fills to your goal, takes the colour of what you drank, and spills over when you go past it.
- Log in one tap from the Track tab, with Undo. A long press still opens the full form.
- Quick Water and Quick Pee pour straight into the matching cup on the Dashboard.
- Flo comes alive: one animated character across the app that reacts when you log a drink, a visit or reach your goal.
- A page to choose your app icon, including a Classic one.
- Request a Refund in Profile, next to your subscription. It opens Apple's own refund form.
- Fluen now speaks Indonesian and Malay.
IMPROVED
- Dark theme uses a true black background.
- Health insight recommendations on the Dashboard connect straight to Flo.
- Cup sizes come in round metric steps, and your cup preferences sync to your account.
- Announcements can show pictures and stay marked as new until you open them.
FIXED
- Widgets, Control Center, Siri and Shortcuts now speak your language instead of falling back to English.
- Time formats follow your 12 or 24 hour setting everywhere.
- Flo memory suggestions appear faster and save instantly.
