Colorectal cancer is now the number one cause of cancer death in adults under 50. Most people ignore their symptoms for years because nobody told them it was worth paying attention to.
No. 2 helps you build a baseline before you need one.
Log your daily gut health in seconds using the Bristol Stool Scale, the same scale doctors use. Track symptoms, build a daily streak, and export a clean PDF summary to bring to your next appointment.
FEATURES
-Log bowel movements in under 30 seconds
-Track discomfort, urgency, frequency, and more
-Build a daily streak and unlock milestones as you go
-View your patterns on a calendar and insights screen
-Export a formatted health summary PDF for your doctor
-Everything stays on your device, your data is yours
No. 2 is not a medical app. It won't diagnose you or tell you what to do. It just helps you pay attention so your doctor has something real to work with.
A cleaner, calmer redesign, top to bottom.

-Smoothed out logging, so tracking a new entry feels quicker and less cluttered
-Fixed a bug where switching tabs could occasionally leave a screen blank
