The Challenge

Children and the elderly are especially vulnerable to inhaler error with no solution available that helps them retain correct technique. Patients also find it difficult to manage and comply with their medication routine, often forgetting if they have taken their daily dose. Because of this, many still have poor control causing exacerbation of symptoms such as shortness of breath and resulting in twice the number of hospitalization and three times higher healthcare costs.

The Whizz, improves the management of respiratory conditions by increasing the efficiency of medication delivered into the lungs while tracking intake data to augment the assessment of treatment outcomes. The Whizz spacer helps deliver medication effectively to patients, paired to a mobile application that has multiple features to track and encourage compliance through gamification as well as manage treatment regimen.

Meracle successfully created iOS version of the Whizz mobile application and were seeking a partner to build a version that runs on Android devices.

Meracle also potentially planned to expand into the Europe, Japan and Taiwan markets in late 2023 and 2024. This must be evaluated while creating the new application. ​

The Solution

SmartDev came up with two different approaches to provide the new applications: building an Android native application and building the application on cross platform technology. In the approach 1, we will build another Android application besides the current working iOS application. The team has finally decided to implement approach 2, which will build cross platform app with React Native tech stacks.​
