TK-Doc App review
A free mobile symptom checker for families, with AI assessments and practical next steps.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
TK-Doc’s Symptom Checker is an AI-powered chatbot in Techniker Krankenkasse’s mobile app. It asks about symptoms and factors such as age, gender and potential risk factors, then provides an initial assessment, possible matching conditions and suggested next steps. It is intended for people seeking an early sense of whether self-care may be appropriate or medical advice is recommended, including families checking symptoms for children or relatives. It is guidance, not a diagnosis or emergency service.
The checker’s scope goes beyond matching symptoms to conditions: it also provides information about causes, treatment and risks, and recommends actions. Users can download a PDF of the assessment results. Use can be anonymous, but the results report is available for 30 minutes. This makes the tool suited to a quick assessment that users may want to retain, while the report’s limited availability is worth considering before starting.
TK-Doc is free and available on iOS and Android, with no web access. TK says members aged 16 and over can use the app free of charge; the checker’s page describes use for people 18 and over while also allowing checks on behalf of children and relatives. Families seeking a free, mobile-first checker with follow-up questions and practical care guidance may find its focus appropriate. It is a less suitable choice for anyone who needs a desktop checker, a diagnosis, or emergency support.
