Fever’s aren’t friendly, Andi is.


Andi is a smart thermometer product that allows users to easily record and understand temperature readings instantly. With the paired app, Andi syncs all of your temperature readings to its database so that you can quickly access, understand and share this information.

The Problem

Temperature readings have become increasingly more important over the past year as users have begun to routinely record their temperatures for work, school, social and health purposes. Traditional thermometers can be intimidating and can cause discomfort to children and adults alike. Especially in households with multiple family members, having to share a thermometer that requires contact with body fluids can be unsanitary. Furthermore, parents typically fail to detect fevers one quarter of the time and struggle to keep an accurate timeline of their child's temperatures.

How can we design a smart thermometer product that alleviates the discomfort that traditional thermometers bring while helping users better understand and track their temperature readings?

The Solution

Andi is a smart thermometer that is friendly, easy to use and accessible. Andi uses infrared technology so that there is no need for skin to skin contact making the product suitable for multiple users. The companion app syncs via bluetooth allowing users to easily track and manage temperature timelines for up to ten profiles. The app also allows users to manually add important information such as weight, medications or symptoms to gain a more comprehensive understanding of temperature readings. Readings can then be shared with medical practitioners, schools and others.

Process Summary


Going into the project, my group had little knowledge about thermometers and what kinds of challenges they brought to users. We wanted to develop a better understanding of how traditional thermometers are problematic, what kinds of limitations they have and where current smart thermometers fall short. To launch our process, we began with a benchmark analysis to see what kinds of smart thermometer products already existed. We realized that there weren't many existing smart thermometers in the market, giving us a lot to consider in designing our product. We then consolidated our findings into a chart to clearly outline the pain points and opportunities in the field, and what kinds of solutions we would be able to implement to fill these gaps. We also started our PACT analysis to establish all the different aspects of our product.

After conducting our preliminary research, there were five clear trends that we noticed. After clearly outlining the key trends, we came up with key questions that we wanted to solve in creating our product.

Infrared thermometers are the most hygienic way to take temperature readings across multiple users with no contact.
Traditional thermometers aren’t intuitive enough to take biometrics into consideration when providing a temperature analysis.
Other smart thermometers can only be used when the user has downloaded and paired with the app making the thermometer useless on its own.
Most thermometers are not designed to be accessible for elderly and disabled users.
No other smart thermometer allows for the information to be shared with others i.e. medical practitioners

Defining our
Target Users

Product Ideation

In designing our product, we began by mapping out the user flow for the device from start to finish and finalized what features the physical product would have. We then moved on to creating four different iterations to see the potential shapes our product could take. These iterations were revised twice before creating the final rendering.

The product takes the form of a vertical stick shape resembling a Wii remote, something that most users are familiar with. It is slightly larger on the top to accommodate for the infrared technology and LED screen and has a thinner bottom with grooves to fit the hand comfortably. The device only has two buttons that complete the tasks of turning the device on and off and recording temperatures. Andi is also equipped with a speaker for text to speech purposes. We’ve designed the product so that it could also be paired with silicone sleeves making the product friendlier, more comfortable, and easier to hold than other thermometers.

Prototyping the Companion App

After designing the product, we moved on to designing the mobile app which began with a systems requirements chart as well as the app’s information architecture. We decided to include three different pages within the app that would fulfil the needs of our users: home where all the profiles would be displayed, calendar where users can easily filter through preferred information, and reminders where users can set notifications to remind them to take readings. After the site map we moved on to creating low, mid and high fidelity wireframes.

User Scenarios

We created four user scenarios to map out how our target users would interact with the product and app,  what journey they would take, and what features they will need.

Final Product

Efficient and Thorough Onboarding
First time users are able to easily set up their account with basic personal information. Additional profiles can be added in the onboarding or through the home page.

Easily access and add information
Users can quickly access their most recent temperature readings and can see a detailed timeline of their temperature history. Through the profile timeline, they can also add important information such as diagnoses, medication, notes, symptoms and manual temperature.

Understand readings and monitor progress
Andi uses the profile’s health information and the user’s manual information inputs to develop a more comprehensive analysis of specific temperature readings. Andi also shows the progress of the users temperature readings recorded across a select period of time. This allows users to monitor a fever’s progress and potential duration.

Calendar and export features
The in app calendar allows users to review specific information on a selected day. This feature is especially useful for users with multiple profiles. Desired information can then be exported along with a covid-19 form if desired.

Temperature Reminders
Andi lets users set post notifications for desired profiles, reminding them to take their temperature recordings on specific days. These reminders can be repeated.

Product Video

We created an animated product video to highlight Andi's core features.



I enjoyed this project as I got to create both a product and an app–something I haven’t done previously. The biggest learning outcome I had was the importance of collaboration and making informed design decisions within a team setting. I also developed a better understanding of the research process in designing a product. What I enjoyed most about this project was furthering my skills in After Effects and Illustrator. I spent a good amount of time creating visuals for our branding and developing our animated product video. 

Going forwards, I hope to develop a 3D rendering of the product that includes its selection of silicone skin and animating the LED screen on the thermometer. I also hope to conduct more user testing to see users are happy with the current features offered.
