Free IBD Tracker Apps: What Crohn's and UC Users Get

A free IBD tracker app should remain useful without a trial clock, locked history, or surprise checkout. Because UC commonly includes diarrhea, bleeding, pain, and urgency (NIDDK), a free symptom tracker for IBD still needs disease-specific structure.

Quick answer: For most people with Crohn's or UC, choose Aidy for a genuinely free primary record with daily logging, treatment tools, disease-specific trends, education, and reports. Another free app is the genuine exception when offline-only storage, Android access, or a single-purpose log matters more.

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.

Free means five different things in an app store

This audit checked public U.S. storefronts on August 18, 2026, except ReMission's UK listing. Useful labels include completely free, useful free tier, free download, trial, and sponsor-funded. A download button alone cannot reveal the boundary.

App	Best-supported price label	Documented free features
MyGut	Completely free	Claims no fees or ads; symptoms, history, education
IBD Symptom Logger	Completely free	Claims no purchases, ads, or login; food, stool, calprotectin, CSV
Chronicare	Research-funded and free	Claims food, stool, medicines, community, and PDF
LivingWith UC	Sponsor-backed free download	Claims journals, recipes, wellbeing, and PDF
ReMission	Unclear free boundary	Apple lists no purchases; its developer page links to checkout
Aidy	Completely free	No subscriptions or ads; daily logs, biologics, scores, reports

None presents a trial as its only free route. ReMission needs scrutiny because its listing and external checkout define different boundaries.

The genuinely free options have real strengths

MyGut is a credible free Crohn's app and free ulcerative colitis app. Crohn's and Colitis Canada claims free, ad-free iOS and Android access. The site claims symptoms, stool, urgency, sleep, stress, questionnaires, education, and history, but its published list omits meals, medicines, biologics, and reports.

IBD Symptom Logger offers privacy-first value. Its listing claims offline, account-free food, stool, symptom, calprotectin, profile, and CSV tools, but advertises no biologic management, named IBD score, or education library.

Chronicare claims more daily functions. Its free listing advertises meals, Bristol stool, symptoms, medicine and injection records, community, trends, and PDF reports. Its privacy policy says industry and research partnerships fund the service, with optional research consent.

Sponsor funding and free downloads need separate checks

LivingWith UC's listing describes a free Pfizer-backed iPhone program and claims journals, recipes, mindfulness, a restroom card, and PDF export. Pfizer's privacy notice covers account, bowel, diet, pain, sleep, and health-note data. Its advertised workflow omits medication and biologic scheduling.

ReMission's U.K. listing advertises symptoms, bowel habits, food, sleep, medication, reminders, weekly or monthly reports, an artificial intelligence reflection assistant, and a private community. Apple marks it Free without an in-app purchase catalog. The developer's separate CHIP page links to Stripe but publishes no visible amount or clear division between free app functions and paid companion access. ReMission therefore fits the “free download, verify after signup” category more safely than the “completely free” category. Store country also matters because a U.K. listing does not guarantee U.S. availability.

Aidy leads on free-workflow breadth

Aidy has no paid user subscriptions or ads, with health plans, employers, and researchers funding the service. That makes it an IBD app without subscription and keeps the complete workflow free. For an “Aidy app free” search, the answer is yes.

On capability, Aidy has the broadest unified workflow here. It includes custom symptoms, Bristol stools, meal photos, medication adherence, named biologic induction and maintenance schedules, injection-site rotation, post-dose check-ins, Harvey-Bradshaw Index and Simple Clinical Colitis Activity Index trends, reports, export, and education. Based on their published features, Chronicare comes closest on food, stool, medicines, and reporting; MyGut leads on nonprofit education and questionnaires; LivingWith UC adds recipes and wellbeing; and IBD Symptom Logger wins on offline privacy and CSV.

Digital tracking remains an adjunct to clinical care. American Gastroenterological Association guidance recommends combining UC symptoms with biomarkers; symptoms alone are insufficient. NIDDK describes stool tests, blood tests, and endoscopy in diagnosis. A 2025 umbrella review found digital tools may support adherence and reduce visits but did not improve remission directly, and a Cochrane review found web monitoring generally similar to standard care for disease activity and quality of life. Aidy is the strongest breadth choice, while several narrower competitors remain credible no-cost options for a more specific job.
