SympLog

Track your health and lifestyle without giving up your privacy.

SympLog is a privacy-focused diary for tracking your symptoms, vitals, sleep, nutrition, medications, and cycle. Discover patterns through detailed statistics and get a clear timeline for your next doctor's appointment while keeping your data 100% on your device. It offers full flexibility for your categories and is optimized for fast, daily use.

FOCUS ON PRIVACY Your most private information stays exactly where it is created—with you: • No account needed: Start tracking immediately without any sign-ups or emails. • Fully encrypted & local: Your data never leaves your phone. We do not track you or use external servers. • App Lock: Secure the app via Biometrics (FaceID/Fingerprint) or a PIN.

TRACK WHAT MATTERS TO YOU Consistent logging is easier with a fast, adaptable interface: • Symptom Tracker: Log severity and notes in seconds. Create custom symptoms to track what matters to you. • Vitals & Measurements: Record weight, blood pressure, heart rate, or create custom values for anything. • Medication Manager: Manage intake with a calendar view, mark doses, and use automated schedules. • Sleep & Mood: Track duration and quality to understand rest patterns. Use the diary for dreams and personal notes. • Cycle Tracking: Log your menstrual flow and see a private estimate of your next cycle based purely on your history. • Lifestyle Logging: Track nutrition, activities, and life events alongside your health data.

DISCOVER PATTERNS & CORRELATIONS Understand your body, find potential triggers, and see how symptoms develop: • Spot Correlations: See how sleep impacts mood, how food relates to your well-being, or how symptoms align with your cycle. • Clear Timelines: Use intuitive charts to prepare for your next doctor or therapist visit. • Visual Trends: Visualize your health data over days, weeks, or months.

HELPFUL TOOLS Stay in full control of your data: • Health Connect (Android) / Apple Health (iOS): Optionally import data from your other apps (read-only, off by default, never shared). • Backup & Export: Create encrypted, password-protected backups or export a CSV for your own analysis. • Encrypted PDFs: Generate a PDF of your complete or filtered journal history for doctor appointments. • Custom Categories: Modify default categories or create your own. • Reminders: Define exactly which days and times you want to be notified. • Dark Mode: Fully supported for comfortable nighttime use.
