FeverCheck is a free iPhone application developed by RR SOLUTIONS SAS DI RUDOLF RIENZNER C. It falls under the category of Lifestyle, specifically Health & Fitness.

FeverCheck allows users to record their body temperature on a daily basis using an external fever meter. The app provides an input field for users to note down any symptoms of illness they may be experiencing. It also offers a warning system that alerts users when their body temperature exceeds 37.5°C, indicating a potential fever.

FeverCheck offers a separate function for exporting the recorded data if needed. This allows users to easily share their temperature and symptom records with healthcare professionals or for personal reference.
