Healsens – Free AI Health Tracker & Mood Journal Healsens is a European AI health and biomarker tracking platform for blood tests, longitudinal health tracking and preventive wellness. Order blood tests through Healsens in supported European countries and receive results directly in the app, or import existing lab results from your doctor or any laboratory worldwide. Track 350+ biomarkers alongside biological age, symptoms, mood, sleep, stress, weight and lifestyle data — all in one longitudinal health record. Built for Europe • Order blood tests through Healsens in the Netherlands and other European markets (where available) —no separate lab portal needed for many wellness panels. • Import existing blood test results from any laboratory worldwide. • Track 350+ biomarkers over time. • Follow cholesterol, glucose, hormones, vitamins, inflammation markers and more. • Compare results across multiple blood tests and see trends instead of isolated numbers. • Biological age insights based on your data and lifestyle context (wellness guidance, not a clinical diagnosis). • Connect wearables and lifestyle data—sleep, activity, habits—alongside labs and mood. Emotions & mood tracker (granular, not just good/bad) • Emotion wheel app – Healsens Modern Emotional Awareness Wheel combines pleasant/unpleasant feelings with energy level and more specific emotion labels. • Granular emotion tracking – Move beyond “fine” or “stressed” and describe your emotional state with greater precision. • AI Emotional Guide – Optional neutral questions and suggestions when naming a feeling is difficult; you always choose what fits. • Mood journal – Log multiple emotions, intensity, energy and context, and follow emotional patterns across weeks and months. The AI Emotional Guide supports wellness self-reflection and emotional awareness — not therapy or diagnosis. Symptoms, habits & daily log • Log headaches, migraines, fatigue, pain, stress, weight, BMI, heart rate, blood pressure, water, alcohol, and custom symptoms. • Spot patterns in your own data—what often appears together over time. • Unit converter (kg/lb, g/oz, cm/in) for global users. AI health insights + doctor-reviewed Health Tips • Explore your blood test results and biomarkers with AI-assisted explanations. • Ask questions about your health data and understand changes across your longitudinal health history. • Access doctor-reviewed educational Health Tips for supported biomarkers. • Follow links to published sources behind the Health Tips, giving you an additional evidence-based reference alongside AI-generated explanations. Healsens is designed to make health information easier to understand while reducing reliance on AI-generated information alone. Health Tips provide educational context, not diagnosis or individualized medical advice. Why one app? Most mood apps don’t store ferritin. Most lab apps don’t ask how you felt that week. Healsens links mind and body on one timeline—blood test tracker app for Europe, mood journal, and prevention-focused wellness log in one place. Privacy Your data is yours. Secure, private, under your control. We do not sell your health data.

Verdict
Healsens and Function Health both sit at 5.0 stars, but that hides the real split: 100% of Healsens's written reviews are positive against 62% of Function Health's. Function Health's advantage is in-app purchases (none vs 2) and ratings volume (25K vs 1). On price, rating, ads and device support there is nothing between them.
