Why SYMPTOLOG?

Symptom Diary

Use SymptoLog as a digital symptom diary to regularly document symptoms, pain, and well-being in a clear and structured way.

Mood & Symptoms

Record your current condition quickly, in a structured way, and always analyzable.

Share easily

Share your evaluations directly with doctors or therapists – digitally or as a printout. (Note: Some practices are technically limited; it's best to check beforehand.)

Privacy

Privacy-first: Your data is stored locally and processed without the cloud. Optionally, you can enable a personal backup (e.g., Google Drive) – fully under your control.

History & Trends

Identify patterns, developments, and connections – helpful for sessions and your own reflection.

Usable everywhere

Optimized for smartphone, tablet and desktop – fast, reliable and stored locally.

Weather data

Weather data can be included to identify possible weather-dependent patterns. Main source: German Weather Service (DWD) (Licences & sources).

Medical appointments

Manage medical appointments and enter notes for the conversation in advance.

Medication intake

Record medications with name, dosage and intake time – clear and traceable.

Start immediately

No account needed – open the app, create your first entry, and off you go.

Clear and focused

All areas are intentionally separated – so you can focus on what matters right now.
