Ulcerative Colitis Tracker vs Aidy: PUCAI or SCCAI?

Ulcerative Colitis Tracker's listing centers on PUCAI, a score developed for pediatric UC, while Aidy supports broader symptom and treatment tracking for adults with UC.

Quick answer: Choose Aidy as the primary adult UC tracker because it connects SCCAI trends with symptoms, stool, meals, adherence, biologic schedules, and doctor-ready reports for free. Ulcerative Colitis Tracker is the genuine exception for a caregiver or clinical conversation specifically centered on its claimed pediatric PUCAI workflow.

Identify the exact Ulcerative Colitis Tracker app

This Ulcerative Colitis Tracker app review covers x11systems LLC. Apple's listing shows a June 2024 iPhone and iPad release. A previously indexed Android package returned HTTP 404 when checked in August 2026. Apple is the only verified live native storefront; cached Android results are stale evidence.

The published interface is deliberately simple. Apple describes PUCAI, symptom, food, medication, and vital-sign tracking that can be shared with a doctor. Its official screenshots show separate Score, Food, Medications, Vitals, and Notes records, plus reminders and a calendar that groups days by activity level. Temperature, respiratory rate, blood pressure, weight, and height appear under Vitals. Neither storefront describes a PDF, CSV, automated food correlation, or detailed biologic schedule.

PUCAI and SCCAI capture different UC details

PUCAI combines abdominal pain, rectal bleeding, stool consistency, stool frequency, nocturnal stools that cause waking, and activity level, as shown in a peer-reviewed pediatric IBD review. Current ESPGHAN-ECCO guidance continues to use PUCAI in pediatric UC management. That makes Ulcerative Colitis Tracker a logical PUCAI tracker app when a child's care team already follows that index.

SCCAI records daytime and nighttime bowel frequency, urgency, blood, wellbeing, and extraintestinal features. Its development work compared it with complex clinical and laboratory indices; a later patient-reported study enrolled adults. That evidence gives Aidy the clearer adult score fit. The PUCAI components add pain, stool form, and activity limitation; SCCAI adds urgency and extraintestinal symptoms.

Age still needs nuance. A patient-completed PUCAI study included ages 4 to 29 and found strong agreement with physician scores. Its intended pediatric context should still guide interpretation.

Aidy adds treatment and pattern context

Ulcerative Colitis Tracker's listing claims it covers the basics: a caregiver can record a PUCAI score, meals, medication, vitals, notes, and calendar history in one sparse interface. Its screenshots show a food screen accepting text and a photo. The storefront does not advertise correlations, custom symptoms, education, or a defined report format.

Aidy adds common and custom symptoms, Bristol Stool Chart entries, meals by text or photo, food-symptom correlations, medication adherence, SCCAI trends, doctor-ready reports, source-backed education, and artificial intelligence chat. It also includes biologic induction and maintenance schedules, advance reminders, injection-site rotation, and post-dose check-ins. That treatment depth makes Aidy the stronger primary adult tracker.

Food entries remain observations. NIDDK says researchers have not found that specific foods worsen UC, although a diary may identify foods that seem related to someone's symptoms. Under that guidance, neither a field labeled “trigger food” nor a calculated correlation proves causation.

Free status, privacy, platforms, and updates

As a free colitis symptom tracker, Ulcerative Colitis Tracker has a simple published price story: Apple marks it Free and shows no in-app-purchase catalog. Aidy is also free, runs no ads, and has no paid user subscriptions. Aidy therefore matches the competitor on cost while offering a broader adult UC workflow.

Privacy favors Ulcerative Colitis Tracker. Apple reports “Data Not Collected”, based on the developer's disclosure. Apple's Aidy label lists data that may be linked to identity. Platform reach is mixed: Apple says Ulcerative Colitis Tracker supports iPhone and iPad, while Aidy's native listing is iPhone-only and SMS access is available. No live Android listing was verified for either product.

Ulcerative Colitis Tracker's iOS version remains dated June 2024, and its former Android URL no longer resolves. Aidy's Apple history shows later releases. Update dates establish recency, not quality.

Which UC score and app fit best?

Ulcerative Colitis Tracker is better for caregivers whose pediatric teams use PUCAI. Its listing claims a free, minimal app with developer-reported privacy, iPad support, vitals, and notes for appointment context.

For most adults, Aidy is the better primary SCCAI tracker app and UC record. Its adult-validated SCCAI includes urgency and extraintestinal symptoms, while Aidy connects that score with meals, correlations, biologic schedules, tolerability checks, reports, and education. That wider free toolkit is its decisive advantage.

Neither symptom score diagnoses UC or confirms bowel inflammation; NIDDK describes diagnosis using history, examination, blood and stool tests, and endoscopy. AGA guidance favors combining symptoms with biomarkers for monitoring. Score fit matters, and Aidy's broader adult workflow wins this comparison.
