Hand washing is more important than ever, and we wanted to create an app to simplify the hand washing experience. We were inspired to build Rinzy because commonly used methods of timing how long we wash our hands, such as counting to 30 or singing Happy Birthday, are both repetitive and unreliable. Another problem we wanted to solve was the measurement of hand washing technique; it’s hard for people to know whether they’re washing their hands correctly or not. One of our goals was to be able to help people wash their hands better, and we aimed to accomplish this by utilizing the Apple Watch gyroscope.

What it does

Rinzy aims to hinder the spread of COVID-19 and other infectious diseases by both encouraging and taking the guesswork out of hand washing. Rinzy is a timer that lets you know when you have washed your hands for 30 seconds. It will also play your favorite music, because who doesn’t get bored while washing their hands? Future versions will also leverage the Apple Watch gyroscope to measure and correct the user’s hand washing technique.

How we built it

We built Rinzy using Swift and Apple WatchKit.

Challenges we ran into

We faced many challenges none of our group members had any previous experience using Swift.

Accomplishments that we're proud of

We are proud that we were able to successfully use Swift to create a watch app, and that we were able to learn so much about app development in this short time frame.

What we learned

We learned a lot about using Swift and creating iOS apps, and we plan to continue working on Rinzy. We also learned to effectively utilize and navigate the XCode interface. Furthermore, due to the current situation, we were able to sharpen our remote collaboration skills.

What's next for Rinzy

In the future, we hope to add features like music, voice activation for the timer, and a tracker that uses the Apple Watch gyroscope to tell users how actively they washed their hands.
