What it tracks

  • Drinks, voids (urinations) and leaks, on one timeline per day.
  • Volume, duration, or both, for any entry - whichever your clinic asked you to keep.
  • Urgency and pain, rated per entry.
  • Nighttime voids and the first void of the morning, tracked separately, because that is usually what gets asked about.
  • A free-text comment on any entry.

Trends and reports

  • Four charts: void frequency, urgency, time between voids, and intake versus output - over a week, a month or a year.
  • A PDF report you assemble yourself: duration, urgency, pain, leaks and comments are each optional, so it can be a bare intake-and-output chart or the full picture.
  • Reports are shared from your iPhone by email or message, or printed.
  • Trends and PDF export unlock together with the one-time purchase.

Privacy

  • Diary entries are kept on your iPhone. They are not uploaded to us, and they are not shared with anyone unless you export a report yourself.
  • No account is needed to use the app.
  • The app collects anonymous crash reports (Sentry) and anonymized usage statistics (TelemetryDeck) so bugs get fixed. Neither contains your diary entries, and the app does not collect your precise location.
  • Full detail: app privacy policy.

Who it is for

People keeping a bladder diary or voiding diary - often before a urology or urogynecology appointment, while tracking urgency, frequency, nocturia or leaks, during pregnancy or postpartum, or while following a treatment plan or testing lifestyle changes.

What Vesi is not

Vesi is a self-tracking tool, not a medical device. It does not diagnose, treat, or advise on any condition. It does not estimate volumes from audio, and it does not replace a conversation with your clinician.
