How to Check Room Temperature with iPhone (Update Guideline)

How to Check Room Temperature with iPhoneWondering how to check room temperature with iPhone?

Sadly, iPhone itself can’t measure temperature even if it has sensors. They aren’t made for the purpose rather than helping the phone to fight unfavorable conditions like overheating or any other sort of damages.

But there’s good news!

You’ll find many different iOS applications and external thermometers that can easily be integrated into your iPhone for accurate temperature measurement.

We’ll go deep inside and explore what apps to use. Also, review some of the best devices for measuring a room’s temperature with ease! Just before we get right into that, here’s why it’s important to monitor your room’s weather condition.

Why You Should Monitor Room Temp Regularly?

measure room temperature

Temperature has a massive impact on air quality. In summer, hot temperature causes more water evaporation from the environment. Consequently, it contains more moisture meaning the air is highly humid.

Humidity over 50% of the air will eventually damage the interior of our home.

It creates a favorable living condition for biological contaminants. Also, water-prone areas will become a breeding ground for mildew and mold that are highly responsible for many diseases.

On the other side, when it's cold temperature, air can't hold enough moisture so it's low humid or dry. When humidity is below 30%, it starts to collect moisture from anywhere it possibly can.

From water-prone areas like shower, kitchen to wooden furniture or even your skin, lips, and nasal passages will dry out because of this dry air sucking up all.

So as you can see, both over humid and low humid air have an impact on our house and health. There comes the necessity to monitor a room’s temp regularly. If it’s over humid, you can use a dehumidifier to control the level.

Besides, you can use humidifiers and other cost-effective solutions to add humidity when it goes below what’s normal.

Does iPhone have a Thermometer? Can You Measure Temperature with it?

Does iPhone have a Thermometer

Talking straight to the question, it does NOT come with a default thermometer. Indeed, the apple smartphone temperature sensor is used for predicting a smooth operation of its functionalities like detecting battery damages, overheating, etc.

However, these sensors are integrated with thermometer software to predict temperature. Now the question is, can iPhone measure temperature with these apps?

The sad news is that it’s not very helpful. The fact is that the phone has its own body temperature and it dissipates heat to the air. That’s why it’s hard to measure accurate room temperature using the unintended sensor.

So, do you still want to measure room temperature on your iOS device?

Well, there are two different options to go -

1. Weather measurement apps.
2. Install temperature measurement thermometers in your room and connect them with your iPhone using their associated apps. (Best Option)

Does Room Temperature App Give Accurate Data?

Does Room Temperature App Give Accurate Data

There’re many thermometer apps for iOS devices. Some of these apps are free to download and have limited features. So for more advanced features, useful widgets, and historical data, you’ll have to pay a fee.

When you install them, they will integrate with your iPhone’s sensor. So that’s how it’ll try to collect weather information and provide you.

However, since it’s the sensor is designed for the phone's functionalities, data accuracy might be compromised. You might not get accurate readings always.

Other apps will connect to nearby weather forecasting services to collect reports. Hence, the prediction is precise but not useful guessed you didn’t want to know the outside weather condition. Actually, maximum app will provide you outside temperature data from their weather prediction system. 

In a nutshell, there are no iOS apps for checking your room temperature accurately!
