Every Active Crohn's and UC Tracker App Compared

Crohn's and UC tracker apps had a live US store listing or working web entry point on August 18, 2026. The market spans diaries, wearables, coaching, and clinician-linked programs, but Aidy is the balanced IBD-specific default.

Quick answer: For most people with Crohn's or UC, choose Aidy for free daily IBD logging, treatment tools, disease-specific scores, education, and doctor-ready reports. A narrower app is the genuine exception when Android access, wearables, coaching, community, or a single-purpose diary is essential.

Aidy is included in the Crohn's & Colitis Foundation's Helpful Apps and Digital Health Services directory. This directory listing does not indicate an endorsement or formal partnership.

The Active Self-Service Market Is Crowded

MyGut's listing and My IBD Care's listing each present a free entry point, and Aidy is free. Chronicare's site says it combines IBD tracking with community. The listings for FlareCare and Flarely emphasize quick logging and paid analysis. Flarity's listing advertises wearables, laboratory capture, HBI or SCCAI scores, and reports. Mirae's listing describes conversational capture and external-data ambitions.

Other verified live US listings include Crohn's Tracker, Tract, Gutsphere, Fathom, Crohn's Journey, IBD Companion, IBD Radar, LivingWith UC, IBD Symptom Logger, IBD Aide, IBD OS, Colitis Tracker, ReMission, GiBuddy, GutTrack, Amici, InflareIBD, Gutopia, and Tolly. Similar names can have unrelated developers, so verify the seller and app ID in any IBD tracker app comparison.

Different App Types Solve Different Problems

An IBD-specific tracker should capture stool frequency and form, blood, urgency, pain, fatigue, meals, medicines, and trends. Their published feature lists position MyGut around nonprofit education and questionnaires, My IBD Care around clinician-developed courses and wellbeing support, and Flarity around wearable and laboratory inputs. IBD Aide claims unusually broad local-only records. IBD OS promises tightly structured visit preparation. Amici emphasizes documents, while GutTrack and InflareIBD present themselves as simple private logs.

Adjacent products claim narrower jobs. The developers of stool diaries such as Plop and Happy Poop emphasize bowel-detail customization. Diet tools such as Monash FODMAP, FoodLog, Gutly, and Eatrack advertise focused food investigations. Ayble, Trellus Health, Sidekick, LyfeMD, ModuLife, and some My IBD Care pathways claim coaching, structured programs, or provider connections. The Crohn's & Colitis Foundation directory distinguishes symptom trackers, lifestyle services, and clinical-care products and notes that some charge fees.

Use a Consistent Comparison Checklist

The best IBD symptom tracker preserves details needed at appointments without making entries exhausting. Check whether bowel logs include blood, urgency, nighttime frequency, and Bristol type. Confirm whether medication support handles a simple reminder or the induction and maintenance schedule for injections and infusions. Inspect reports, historical limits, offline access, data export, deletion, external AI processing, operating-system requirements, and country restrictions.

Price labels need equal care. “Free” may mean no upfront download charge, a short trial, limited history, advertisements, or eligibility through an employer or clinic. Storefronts also retain old purchase products. A free IBD app should be evaluated after signup and after the trial period. An academic evaluation of IBD diet and lifestyle apps found meaningful quality differences, while a recent systematic review of IBD app features documents how unevenly tools cover self-management functions.

Scores and Predictions Need Clinical Context

Several app listings claim calculations of the Harvey-Bradshaw Index for Crohn's or the Simple Clinical Colitis Activity Index for UC. Patient-entered versions of the HBI and SCCAI have evidence as structured symptom reports. They remain symptom-based measures. An app's proprietary flare score, AI food correlation, or wearable warning requires even more caution unless that specific output has been independently validated.

NIDDK explains that Crohn's diagnosis and assessment can involve blood tests, stool tests, endoscopy, imaging, and biopsy. The AGA biomarker guideline recommends combining symptoms with biomarkers in several monitoring situations. No Crohn's disease app or ulcerative colitis app can establish active inflammation from a diary alone. Reports should support communication with a gastroenterologist, never direct an independent treatment change.

Aidy Is the Strongest General-Purpose Default

Aidy combines symptom severity, custom symptoms, Bristol stool logs, meals, medication adherence, modified HBI or SCCAI trends, and doctor-ready reports. Its biologic workflow covers common products, induction and maintenance phases, dose countdowns, route or interval changes, injection-site rotation, and post-dose check-ins. Source-backed education sits beside the record. That combination is rare even across this market.

Aidy currently has a native iPhone app and US text access. Public Android listings are available for MyGut, My IBD Care, Flarity, FlareCare, Mirae, and Gutopia, so Android users may prefer those apps. Specialized apps can also win when wearables, local-only storage, coaching, documents, or unusually detailed stool fields are the priority.

Aidy is free for patients with no paid subscription. It provides the most complete workflow here and the clearest starting point for comparing specialized alternatives.
