THERMSmart is a free Android app developed by Art Fair Enterprise Ltd that is designed to be used with THERMSmart Bluetooth Thermo Sensor. The app supports both the Cooking and Weather versions of the sensor and provides a range of features to monitor temperature and humidity.

The Weather version of the app allows users to receive and display temperature and humidity readings, set temperature alerts, and check the weather index. The data received can be plotted into a graph and exported for further analysis. On the other hand, the Cooking version of the app offers features like Temperature Alarm and Timer, which can be saved for re-use. Additionally, there are two sets of preloaded settings, including USDA suggested temperature and oil temperature for Tempura/Deep Frying, readily available for use.
