Australia prides itself on its strong ‘drinking’ culture. Many Australians as young as 18 years partake in the consumption of alcohol with their friends, family and work colleagues. We wanted to promote safe consumption of alcohol amongst such young Australians, especially since they are inexperienced in regard to consuming alcohol as per the Australian Guidelines.

For this reason, we have developed an personal alcohol consumption tracker that not only follows Australia's alcohol consumption guidelines, but is also personalised to the user and allows them to select/track the alcohol they consume based on liquor type, brand and their consumption amount. In this way, we would like to promote sake drinking habits in the Australian population.

What it does

Alchie is a mobile application that acts as a personal alcohol tracker, as the user can record what alcohol they have consumed and how much. The user will login to the mobile application, record the drinks they have consumed, with the number of standard drinks they have consumed. Having 4 standard drinks and over is considered binge drinking as per the Australian Guidelines, so users will be notified as they reach and go past the 4 standard drinks mark.

We also have a separate page providing users with emergency (000) and helpline phone numbers, that can be dialled at the touch of a button.

How we built it

This mobile application was developed using the Flutter framework (Dart programming language) on the client side. The application was hosted on AWS Elastic Beanstalk. The Spring Boot framework (using Java programming language) was used on the server side. Swagger Codegen was also used to generate APIs for the Flutter application.

Challenges we ran into

-Understanding the database relationships for the back-end. -Difficulties in deciding which video editing software to use for working on the pitch. -Had difficulty adding the Swagger-generated APIs to the Flutter application. -Formatting issues in the front-end. -Managing the audio in iMovie for Windows software.

Accomplishments that we're proud of

-Implementation of the AWS back-end. -Achieving the desired formatting for the application.

What we learned

-Learnt to develop a mobile application via the Flutter framework. -Understood how alcohol is classified and recognised (especially in Australia).

What's next for Alchie

In the future, we would like to expand our drinks list and increase the list of serving sizes for the alcohol to account for various drinking habits. We want to upgrade our current app to implement a system that allows for the use of a standards drink counter at restaurants or bars, to make it possible for the user to count their alcohol based on the drinks they consume when going out as well. In addition, we would like to implement image recognition software (e.g. Amazon image rekognition) to recognise the drinks by scanning them with the mobile’s camera and automatically calculate the standard drinks consumed, instead of the user having to manually input everything.
