## What is SympLog Health Journal?

Track your health and lifestyle without giving up your privacy.

SympLog is a privacy focused diary for tracking your symptoms and lifestyle. Log your vitals, sleep, nutrition, medications, cycle, and more. 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 and easy daily use.

SympLog is a personal lifestyle and wellness tracker, not a medical device. It does not diagnose, treat, or prevent any medical condition.


FOCUS ON PRIVACY
Local storage is the heart of the app. Your most private information stays where it is created—with you. That is why:
• No account needed. Start tracking immediately without any sign ups or emails.
• Your data is fully encrypted and stored locally on your device.
• Your data does not leave your device. We do not track you or store your information on external servers.
• You can activate extra security by locking the app via Biometrics (FaceID/Fingerprint) or a PIN. Your data is encrypted in any case.


TRACK WHAT MATTERS TO YOU
A solution that adapts to you and is fast to use, because consistent logging is easier when the interface is simple.
• Symptom Tracker: Log severity and notes in seconds. Create your own categories and symptoms to track exactly what matters to you.
• Vitals and Measurements: Record weight, blood pressure, heart rate, temperature, blood glucose, or water intake. Create custom values for anything you want to monitor.
• Medication Manager: Manage your intake with a simple calendar view. Mark doses as taken and use schedules that help fill in dates automatically.
• Sleep and Mood Journal: Record sleep duration and quality to understand your rest patterns. Use the sleep diary to write down dreams and other personal notes.
• Cycle Tracking: Log your menstrual cycle and flow on a calendar and see a private estimate of your next cycle, based purely on your own history.
• Lifestyle Logging: Track nutrition, activities, and life events alongside your health data so everything stays in one place.


DISCOVER PATTERNS AND CORRELATIONS
Consistent logging helps you understand your body, find potential triggers, and see how symptoms develop over time.
• Find correlations between factors, such as how sleep quality impacts your mood, how specific foods relate to your well being, or how your symptoms and mood align with your menstrual cycle.
• Use clear timelines and charts to prepare for your next doctor or therapist visit.
• Visualize your health trends over days, weeks, or months with clear statistics.


HELPFUL TOOLS
You stay in full control of your data and how you want to log.
• Apple Health: Optionally import data from your other health apps and devices (read only). Off by default, encrypted on your device, never shared.
• Backup and Export: Create encrypted, password protected backups to move your data safely or export it as a CSV for your own analysis.
• Encrypted PDF Reports: Generate a PDF of your complete journal history or just a currently filtered view—ready for your next doctor's appointment.
• Custom Categories: Easily change default categories or modify your own in the settings.
• Reminders: Create multiple reminders and define exactly which day and time you want to be notified.
• Built for Speed: A fluid interface designed for daily use to make logging feel effortless.
• Dark Mode: Fully supported for comfortable night time use.


DEVELOPED IN SWITZERLAND
Developed by BitByBit.ch with a passion for privacy respecting tools that keep users in control of their data.
