Aidy vs Mirae Health: Which IBD Companion Fits Daily Life?

Aidy and Mirae offer distinct UC tracking experiences: Aidy creates a structured daily record, while Mirae's listings describe a conversational AI companion available on iPhone and Android for day-to-day life with Crohn's or UC.

Quick answer: Choose Aidy as the primary UC tracker because it creates an auditable free record of stool, symptoms, meals, medicine adherence, biologic schedules, SCCAI trends, and clinician reports. Mirae is the genuine exception for someone who prefers the conversational AI experience and Android availability its listings advertise.

What Mirae Has Actually Shipped

The current Mirae Google Play listing describes a plain-language diary that builds a health timeline from symptoms, flares, bowel movements, energy, medications, food, sleep, and stress. The listing says it includes medication reminders, appointment summaries, and recent bathroom-finding support. Mirae’s website also advertises photo input, laboratory results, possible pattern analysis, and permission-based connections to available health records and wearables.

Mirae’s own company page calls the product live and “still learning,” a useful warning against treating every planned connection or AI insight as equally mature. Mirae’s strongest current advantages are a conversational interface, a native Android option, and a broader ambition to combine self-reports with outside clinical and wearable data.

Conversation Versus Structured UC Logging

Mirae says a user can describe what happened in ordinary language, then have the app attempt to organize that account. This can reduce the burden of navigating forms when fatigue or urgency makes detailed entry feel difficult. In a qualitative study of real-time symptom monitoring in UC, participants described greater awareness and a sense of control, while also identifying practical burdens.

Aidy favors more visible structure. It records bowel movements using the Bristol scale, urgency and other symptom severity, custom symptoms, meal photos or text, medication adherence, and food-symptom correlations. The structured fields make it easier to see what was captured and repeat the same observation over time. Aidy gives a person with UC a more auditable record when stool, blood, urgency, meals, and treatment timing need consistent definitions.

Treatment Tools and Appointment Reports

Mirae says it records medications, sends reminders, and prepares a summary the user can choose to share. Its website says it can bring scopes, laboratory results, diagnoses, medicine, and daily context into appointment preparation.

Aidy covers routine medication adherence plus configurable biologic induction and maintenance phases, dose countdowns, injection-site rotation, post-injection or infusion check-ins, and later route or interval changes. The original SCCAI study found strong correlation with established clinical and laboratory-based indices, supporting its use in initial assessment. A self-reported score still cannot show inflammation by itself. For someone on biologic therapy, Aidy’s explicit schedules and adherence history make its appointment report the more complete UC treatment record.

AI Insights Need a Clear Boundary

Mirae is unusually direct about this limit. Its website says its AI may be incomplete or wrong, and its terms say the platform does not provide medical advice, diagnosis, or treatment. A 2025 systematic review of health-advice chatbot studies found large reporting variation and noted that fewer than one-third addressed ethical, regulatory, and patient-safety implications. That research did not test Mirae itself. It still supports healthy caution around conversational medical outputs.

Aidy’s patterns and symptom scores support care conversations; they do not prove what is happening clinically. The AGA UC biomarker guideline favors combining symptoms and biomarkers in many monitoring situations. NIDDK describes blood tests, stool tests, and endoscopy as tools for diagnosis and assessment. Mirae’s AI can help organize questions. Aidy’s structured trends can help organize evidence. Clinical decisions still require the wider medical picture.

Free Access, Privacy, and the Better Fit

Mirae states that it has no paid patient plan, trial period, or card requirement. It says health systems and payers fund the service through shared savings. Aidy is also free with no patient subscription. Price is therefore a tie for patients comparing the two services.

Mirae’s privacy policy says chat health information can be sent, after consent, to third-party AI providers including OpenAI, Anthropic, and Amazon. It also describes permission-based EHR and wearable connections, de-identified research, and possible sharing with academic or pharmaceutical research partners. Aidy data is encrypted, exportable, and deletable, with no ads or sale of patient information.

Mirae is better for conversational logging, native Android, and people who want to connect external records or wearables. Aidy is the stronger overall UC tracker for granular symptoms, consistent stool fields, medication adherence, biologic organization, SCCAI trends, and a clearly structured report. Aidy’s deeper IBD treatment workflow gives it the edge for daily ulcerative-colitis management.
