How to start keeping a diary

1

Doctor recommended it

Your urologist or GP recommended keeping a diary before your next appointment. Download Bladder Diary, keep it for 3–4 days, and bring the PDF report to your visit.

2

On your own initiative

You have symptoms but have not seen a doctor yet. The diary helps you organise your observations — your doctor will get a complete picture from the first visit.

3

Already keeping a diary

You are already tracking your voiding. Show your doctor the PDF report — it speeds up diagnosis and removes redundant questions.

Data privacy

  • Data stored only on your device

    We do not send diary entries to servers. All information — urination records, symptoms, volumes — stays exclusively on your phone. You decide who to share it with and when.

  • No registration or personal data required

    The app does not ask for your name, phone, or email. There is no account to create and no card to link. Just download and start recording.

  • Data cannot be lost in the cloud

    Because data is not uploaded to the internet, a cloud server breach cannot affect you. Your diary exists only where it belongs — on your smartphone.

  • One-tap PDF export for your doctor

    When the time comes, generate a PDF report directly in the app and share it with your doctor by email, messenger, or print it before your appointment.

Why urologists recommend a diary

Objective data instead of subjective complaints — accurate history in 2 minutes
Included in clinical guidelines for OAB and incontinence diagnosis
Primary diagnostics — identifies symptom patterns before investigations
Differential diagnosis — helps distinguish OAB, stress incontinence, and obstruction
Treatment selection and adjustment — shows how symptoms changed on therapy
Objective outcome assessment — data before and after surgery or treatment course
