Wave Health vs Aidy for Crohn's: Which Report Helps More?

Wave Health's materials describe a chronic illness treatment journal, while Aidy organizes free Crohn's tracking around gastroenterology appointments and reports.

Quick answer: Choose Aidy as the primary Crohn's tracker because its free, disease-specific record connects symptoms, stool, meals, adherence, biologic schedules, modified HBI trends, and doctor-ready reports with less setup. Wave Health's claimed exceptions are cross-condition tracking, wearable data, vital signs, and customizable wellness fields.

Decision factor	Aidy	Wave Health (public claims)
Best for	Crohn's appointments	Multi-condition tracking
Daily IBD record	Symptoms, stool, meals	Symptoms, activities, measurements
Treatment tools	Medicines and biologics	General treatment journal
Reports and insights	Modified HBI and reports	Claimed correlations and reports
Access and cost	Free; iPhone and text	Platforms and Premium vary
Overall pick	Primary Crohn's tracker	Cross-condition wearable data

Wave captures a broad treatment journey

Any Wave Health app review should recognize how much context it can collect. The current iPhone listing describes physical and mental symptoms, mood, sleep, hydration, exercise, medications, treatments, notes, contacts, appointments, journal entries, menstruation, urination, bowel movements, and custom trackers. Apple Health can import wearable data. Wave’s patient guide also documents Health Connect integration, multiple conditions, medication reminders, visual calendars, personal insights, and a complete data export.

That claimed breadth is valuable when Crohn’s overlaps with pain, fatigue, anxiety, menstrual symptoms, or another serious diagnosis. Crohn’s itself may involve diarrhea, abdominal pain, weight loss, fatigue, fever, joint pain, eye symptoms, and skin changes (NIDDK). Wave's materials claim users can place many of these experiences beside sleep, activity, and treatment and also advertise Bristol stool logging. As a general health diary, Wave asks the user to choose which signals deserve space, and that flexibility is its central advantage.

Aidy gives the report Crohn’s context

For a Crohn's doctor report app, the usefulness of a chart depends on the data behind it. Wave claims users can share a filtered calendar for free or request a full export. Its patient guide says Wave+ adds a weekly PDF with seven days of entries and trends drawn from the prior three weeks (Wave patient guide). That advertised summary may suit someone documenting several treatments or updating more than one specialist.

Aidy's disease-specific report combines IBD symptoms, Bristol stool, meals, adherence, biologic timing, and modified HBI trends. The record supports biologic phases, reminders, injection sites, post-dose check-ins, and schedule changes. Crohn's treatment may include biologics and other medicines selected around individual disease factors (NIDDK). Linking symptoms to treatment gives Aidy's report a clear GI-visit purpose.

Modified HBI creates a consistent symptom snapshot. It is prominent in practice and pragmatic trials, although conversion to other patient-reported measures has uncertainty (PubMed). Wave claims customizable fields but documents no IBD activity index or comparable biologic workflow.

Neither report measures inflammation by itself

A polished report can improve recall without establishing whether Crohn’s inflammation is active. NIDDK explains that clinicians may use blood tests, stool tests, endoscopy, and imaging when diagnosing and assessing the disease. The American Gastroenterological Association recommends combining symptoms and biomarkers in several monitoring situations, with both inputs informing decisions.

That limit applies to both products. Wave’s broad charts can surface questions across conditions, while Aidy’s HBI trend organizes the symptoms a gastroenterology team expects to discuss. Research on an IBD point-of-care dashboard found that a shared view helped patients and care teams develop common language around symptoms, goals, and wellbeing (PubMed). A Cochrane review found web-based IBD monitoring probably has similar adult disease activity, flare, and quality-of-life outcomes to usual care, with a possible small adherence benefit (Cochrane). The report supports care; it does not replace tests or clinical judgment.

Price, access, and privacy shape the verdict

Wave's storefronts claim its core app is free on iPhone and Android. Its Google Play listing was updated in April 2026 and confirms in-app purchases. The official page claims Weekly My Reports come with a three-week Wave+ trial, after which users choose a monthly or annual plan. For anyone checking the Wave Plus price, Apple currently displays Wave+ at $13.99, a six-month subscription at $54.99, and a one-year subscription at $124.99. The exact offer should be confirmed at checkout.

Wave’s privacy policy says it encrypts personal data in transit and at rest, may use de-identified data for research and machine-learning development, and discloses personal information under specified circumstances. Google Play says personal and health data may be shared with third parties. Users should review both disclosures, particularly when connecting wearables or several diagnoses.

Aidy is free with no paid user subscriptions, carries no ads, encrypts data, and does not sell it. Wave claims free core access but reserves its weekly reports for Wave+, whose published subscription prices reach $124.99 yearly. Wave wins on Android access, wearables, multi-condition range, and general treatment journaling. Aidy is the stronger free Wave Health alternative for Crohn’s because its report arrives with IBD symptom structure, biologic context, adherence, food and stool detail, and HBI trends already connected.
