Room Temperature Thermometer is a straightforward utility app designed for taking quick ambient temperature readings. For someone wondering if a bedroom is suitable for sleeping or if a home office is at a comfortable working temperature, this app serves as a convenient digital substitute for a physical thermometer. Its primary function is to display a real-time temperature reading by utilizing the internal sensors within the iPhone itself, presenting the data in a clear, large-font digital display.
Key features for this use case include the ability to view readings in both Celsius and Fahrenheit, a simple interface with no complex setup required, and the option to view historical minimum and maximum readings, which can help identify temperature trends in a specific room over a few hours. This is particularly useful for monitoring a nursery, checking a basement, or verifying the consistency of a thermostat's reading.
However, it's important to note the app's limitations. Reviews indicate the accuracy is dependent on the iPhone's own hardware, which can be influenced by the device's own heat generation if it has been used heavily. For critical applications like monitoring sensitive equipment or medical supplies, a dedicated, calibrated hardware sensor would be more reliable. The app also displays basic humidity data. While it contains ads, they are reported as non-intrusive for casual use. For a free, immediate solution to settle debates over room climate or to get a general sense of indoor conditions, Room Temperature Thermometer provides a functional answer.

I use this to check if my baby's room is at the right temp before naps. It's not lab-grade, but it gives me a good enough idea so I'm not constantly buying little standalone thermometers.
