About this app

Bladder Diary turns each bathroom trip into one tap, and turns weeks of taps into a chart your doctor can actually read.

HOW IT WORKS
1. Tap once when you go. That's a complete entry.
2. Measuring? Add the amount with the number pad, or stack the presets (200 + 50 = 250).
3. Log what you drink on the same timeline, so you can see what came before each trip.
4. Open the chart tab, or export a one-page summary before your appointment.

WHAT MAKES IT DIFFERENT
- Logging is never interrupted. One tap saves; no full-screen ad stands between you and the record.
- Every entry can be edited or deleted. Wrong time, wrong amount, wrong day - fix it in two taps.
- A real by-the-hour chart. Not just daily totals. Night hours are shaded so you can see when they cluster.
- Type exact numbers. A large keypad, not a scroll wheel.
- Your own presets. Change the mL buttons to match your measuring cup.

WHAT YOU CAN RECORD
- Time of each void, and the volume if you measure it
- Urgency, leaks, and pad changes
- Fluid intake by type: water, coffee, tea, soda, alcohol, soup

WHAT YOU GET BACK
- Voids per day, split into daytime and night
- Average and largest void
- Total intake and how it lines up with your voids
- A by-the-hour chart for a day, a week, or a month
- A one-page image you can send to your doctor, plus CSV for your own records

FOR YOUR APPOINTMENT
Urologists routinely ask for a few days of bladder records before a visit. The export screen builds that page for you: the numbers, the hourly chart, and the date range, sized to fit one screenshot.

PRIVACY
Your records stay on your device. Nothing is uploaded. Files you export go only to the app you choose to share with.

IMPORTANT
This app is a logging tool. It does not provide medical diagnosis or treatment, and it does not calculate clinical scores. If you have symptoms, talk to a healthcare professional.

Open it, tap once, done.
One tap per bathroom trip. Your log becomes an hourly chart you can share.
