Business Goals:
The main goal was to make an Android app that works offline and safely stores credit and debit transactions. The app had to have a clean, easy-to-use interface and support password protection, PDF generation, handling multiple currencies, and a way to back up and restore data.
Challenges:
We had to deal with several real-world problems to make this vision a reality:
There was no digital system to keep track of and manage daily transactions.
Users didn't have a safe and easy way to store sensitive financial information.
There was no way to make financial summaries that could be shared.
Need for an offline solution that doesn't use a lot of resources.
Need for sorting transactions by date and supporting multiple currencies.
These weren't just technical problems; they were "usability puzzles" that needed a lot of understanding of the end user.
Solutions Delivered
We built a robust Android app that is user optimised supporting complex business logic for all non-technical users. It offers usability, offline reliability and efficiency.

3. Development: Built core modules that work offline.
4. QA and Testing: App testing on a variety of devices and Android versions.
5. Deployment: Released to the Google Play Store and set up to collect structured user feedback.
6. Maintenance: post launch updates and changes based on user reviews and real-time analytics.
