German startup TimeTeller has introduced a saliva test kit designed to help individuals understand their circadian rhythms, potentially reducing side effects from cancer treatments. Led by CEO Angela Relógio, the company emphasizes the importance of timing in treatment effectiveness, aiming to personalize medicine based on individual biological clocks.

The startup has gained traction, particularly among longevity clinics, and has partnered with Techniker Krankenkasse, a major German health insurer, to reimburse the test for certain cancer patients.
