Aidy or MyGut for Ulcerative Colitis Tracking?

Choosing between Aidy and MyGut starts with deciding what matters most in your daily UC tracking routine. MyGut's public materials describe a free ulcerative colitis tracker, Crohn's and Colitis Canada app, UC symptom app, and MyGut alternative.

Quick answer: Choose Aidy as the primary UC tracker for its connected stool, symptom, meal, medication, biologic, SCCAI-trend, and clinician-report workflow, all free. MyGut is the genuine exception for someone who needs its advertised native Android app or specifically wants its publicly described questionnaires and education.

Aidy vs MyGut at a glance

The organization says MyGut records pain, bowel movements, urgency, sleep, stress, and overall well-being, then presents those entries in an appointment timeline. It also describes MyGut as free, ad-free, and available on iOS and Android.

Aidy features include meal photos or descriptions, symptom severity, custom symptoms, Bristol Stool Chart entries, medication adherence, biologic reminders, injection-site rotation, post-dose check-ins, trends, and doctor-ready reports. Aidy also calculates a self-reported Simple Clinical Colitis Activity Index trend from logged information. The original SCCAI study describes the index as a clinical symptom-based tool for initial assessment, so the trend supplies structured symptom context. This is the more treatment-centered design.

What MyGut does well for ulcerative colitis

Crohn's and Colitis Canada says the flare checker and quality-of-life questionnaires provide a repeatable way to reflect on symptoms and day-to-day impact. The organization says the My Health timeline keeps those responses together with journal entries and hospital visits. It also says MyGut supplies an education library, which may appeal to people who already use the charity's resources. The current Apple listing says virtual monitoring and secure messaging are being piloted with selected users and clinics, although those features are not presented as generally available.

MyGut is also the easier choice for someone who needs a native Android app. Its Google Play listing shows the Android release and a March 2026 update, and the developer describes the same core questionnaires.

Where Aidy offers more UC tracking depth

Aidy is the stronger fit when you want one record connecting symptoms with treatment and food. Aidy includes food-photo logging, treatment tracking for pills, injections, and infusions, trend analysis, and physician-friendly exports. It also includes biologic dose countdowns, reminders, injection-site rotation, post-dose tolerability check-ins, medication adherence summaries, food-symptom correlations, and an automatically calculated SCCAI trend.

That wider scope reduces the need to reconstruct medication timing or meals from another app before a visit. It also gives a gastroenterology team a prepared report for review before an appointment. The value remains organizational. Symptoms alone cannot establish how much intestinal inflammation is present. Doctors may use blood tests, stool tests, and endoscopy when evaluating ulcerative colitis, as outlined by NIDDK's diagnostic guidance. The 2025 American College of Gastroenterology guideline also recommends objective monitoring tools such as fecal calprotectin or intestinal ultrasound when assessing clinical response.

Cost, access, and privacy

Crohn's and Colitis Canada says MyGut has no fees or ads. Aidy is free to use, has no paid patient subscription, runs no ads, and does not sell user data. Aidy offers a native iPhone app plus a text-message experience that requires no installation, while Crohn's and Colitis Canada says MyGut offers native iPhone, iPad, and Android apps. Android users who want a conventional app therefore have a clear practical reason to prefer MyGut.

MyGut says entries remain in a private dashboard with in-app account deletion. Its Google Play disclosure says data is encrypted in transit and deletion can be requested, while also indicating that some personal information may be shared with third parties. Aidy data is encrypted and can be exported or deleted.

Which free ulcerative colitis tracker fits you?

MyGut fits people who want straightforward symptom journaling and structured well-being questionnaires, Canadian nonprofit education, or an Android app. Its timeline creates a useful prompt for discussing recent symptoms and hospital visits. Aidy fits people who want a more connected ulcerative colitis record, especially when biologic timing, medication consistency, meals, stool patterns, SCCAI trends, and a shareable report all matter.

For the broadest day-to-day UC workflow, Aidy has the more complete documented feature set while remaining free. MyGut retains meaningful advantages in Android access and Crohn's and Colitis Canada content. Neither app can determine whether symptoms represent active inflammation or replace the clinical tests used to assess ulcerative colitis. The practical choice is the tool whose daily inputs match the information you and your care team regularly review, with Aidy offering more depth when treatment organization and appointment preparation are priorities.
