How it works

Three quiet steps for a clearer prep week

  1. 1

    Set your procedure date

    Enter the appointment once. Happy Colon works backward from that morning so the week is easy to follow.

  2. 2

    Follow Happy Colon timing

    Split doses, last sips, and when to stop eating, laid out hour by hour, not buried in a PDF.

  3. 3

    Scan and track prep scores

    Snap a picture, 0–9 score, prep-week guide, not a lab result.

Who it is for

People with an upcoming colonoscopy who want a clearer prep week

If you have a date on the calendar and a packet of instructions that still feels overwhelming, Happy Colon is for you.

It keeps timing, meals, and visual progress in one place so you can focus on showing up ready.

Built for adults preparing at home, first-timers and people who have done this before.

What stays simple

  • One schedule counted back from your procedure morning.
  • Scoring can stay on your device. Follow your clinician if the two disagree.
  • A score you can glance at, not a lab report.

What it is not

Honest limits, in plain English

  • Not a medical device

    Happy Colon is a companion app. It is not FDA cleared and does not claim clinical accuracy.

  • Not a diagnosis

    Scores are a prep-week reference, not a finding about your health or the exam itself.

  • Not a substitute for your doctor

    Always follow the written prep your clinician sent. If the two disagree, their instructions win.
