About the Project
This app allows users to view the value of currencies, mainly focusing on the US Dollar. The main idea is to compare the value of the Brazilian Real (BRL) with the US Dollar (USD).
Users can check the current value of a currency, view historical price charts to understand trends, access other currencies, set price alerts, and manage general app settings such as language and primary currency.
For users in Brazil, the app also includes an import calculator for products. This tool estimates the taxes and fees that may be applied depending on the value of the imported product.
Unlike the web version of the project, the mobile application introduces different challenges.
Publishing an app on the Google Play Store requires creating a developer account and completing a testing period of at least 14 days for each application.
During this period, testers need to use the app frequently to ensure it works properly. After the 14-day testing period, it is possible to request production access. At this stage, the app goes through a review process and, if no issues are found, it is approved and allowed to be published on the store.
