How it works

This is where your gut data begins.


On desktop, scan the QR code with your phone or create an account to get started. On mobile, tap the link to download the app and start your first scan.

Set up your profile for better insights.


Once you create your account, you can start scanning right away. You’ll also have the option to add a few details about your health, habits, and symptoms. The more context you provide, the more accurate and useful your insights become.

You can scan first and fill this in later. Only basic information is required upfront.

It’s time for your first scan!

When you’re ready, take a photo after a bowel movement and upload it in the app. You can take the photo directly in Faex for privacy, or upload one from your camera roll, whatever feels more comfortable. There’s no prep, no timing rules, and no special setup.

One photo creates your first data point.

Your gut health scorecard.


Every scan gives you an immediate gut score based on that specific stool. This shows what your gut is signaling in the moment, including digestion, composition, and potential concerns.

Over time, Faex combines your scans into a gut health scorecard. This is your bigger picture. You see your overall gut grade, average score, trends, and patterns across 7 days, 30 days, or all time.

The scan score shows what’s happening now.
The scorecard shows where you’re heading.


Meet Felix, your gut data translator.


Felix is Faex’s AI assistant. He helps you understand what your gut data actually means. After each scan, Felix connects your score, trends, and patterns into clear insights you can act on.

Instead of generic advice, Felix looks at your scans over time and explains what might be influencing your gut, like diet patterns, digestion changes, or consistency shifts. You can ask questions, explore insights, and get context without digging through charts or guessing.


The pre-disease screener.


Faex screens for 15+ gut-related conditions using your stool data, including IBS, celiac disease, Crohn’s, and colorectal cancer. You can run a disease screen every 7 days using your at-home scans.

Some conditions require more data than others. Each scan adds context, helping Faex learn your patterns and refine results over time. This lets you track changes, spot early signals, and make informed decisions before symptoms take over.


Your gut doesn’t exist on its own.


Faex brings everything together in one place. Inside the app, you can explore trends over time, earn badges for consistency, and use trackers for things like water, sleep, exercise, mood, travel, medications, and allergies. You’ll see how these factors connect to your gut patterns, not as separate data points, but as part of a bigger picture.

Faex also includes guided tasks and medical citations to add context and credibility to your insights. The more you explore, the more clearly your data comes together.
