Indoor thermometer

What it does

Indoor thermometer checks the temperature around your phone using its built-in temperature sensor, where available. It also shows outdoor conditions based on your location, giving you a quick comparison between the room you are in and the weather outside. It suits anyone who wants a simple temperature check without carrying a separate thermometer, especially at home or while travelling.

Best suited to sensor-equipped phones

The app depends on the hardware in your device, so results can vary between phones. Some models do not include a suitable ambient temperature sensor, while others may report readings affected by the phone’s battery or processor heat. For a more useful indoor reading, the phone needs time to sit unused and cool down rather than being measured immediately after heavy use or charging.

Simple readings, with practical limits

This is a focused utility rather than a full weather station. Its value comes from putting indoor and outdoor temperature information in one place, not from replacing dedicated environmental equipment. Location and network access support the outdoor reading, while the indoor result depends on the phone’s sensor and its surrounding conditions. If you need consistent precision for heating, storage, or monitoring a room, a dedicated thermometer remains the safer choice.

Why it stands out

Indoor thermometer has earned a 4.61 rating from 24,804 reviews and has passed 1,000,000 installs. Those figures suggest it works well for a broad group of users looking for a straightforward temperature tool. Developed by Sweetvrn, it is most compelling when your phone includes the required sensor and you want a fast, readable estimate rather than a collection of extra weather features.
