Development Challenges

Ensuring Up-to-Date Financial Data

Grassfeld's features heavily rely on transaction history, and any new or modified transaction can invalidate related data like budgets and financial goals.

Solution

To track this, we crafted reactive Grassfeld software that always displays real-time financial information.

Developing Extensive User Interface

With over 130 pages, menus, and pop-ups, creating the UI for Grassfeld was a significant challenge.

Solution

Leveraging the Flutter framework allowed us to build a flexible UI Kit and reuse components, saving valuable time and effort.

Supporting Multiple Locales

Grassfeld supports over 20 locales, requiring robust localization capabilities.

Solution

By utilizing the Crowdin platform and built-in Flutter features, we localized not only text content but also time, currency formats, and even image and video content.

Device Compatibility

We aim to support a wide range of customer devices.

Solution

Thanks to Flutter, Grassfeld mobile apps run on iOS 12.0 and Android 5.0, covering approximately 99.5% of active mobile devices. Additionally, iBilly Navigator, a progressive web app, functions smoothly on modern web browsers.

We consider ourselves fortunate to have such an amazing community that consistently provides us with valuable feedback to enhance iBilly as a product.

Data Encryption: All stored data and cache is encrypted to ensure data security.

Secure Communication: Communication with the backend is conducted via secure HTTPS connection.

2FA Authentication: A two-factor authentication process is implemented for secure app access.

Biometric Security: Leveraging biometric solutions like Face ID and Touch ID for for enhanced user experience and protection.

Conclusion

With more than 15,000 banks on board, 18 languages support, web and mobile presence iBilly is a challenging project to build. Careful planning and decomposition allowed us to release it on time and within the initially estimated budget. We used Flutter as a backbone of our technological solution, time showed that this was the right choice.

Looking ahead, it is clear that the absence of iBilly in the MacOS and Windows App Stores leaves a noticeable void that we will fulfill thanks to Flutter’s multi-platform capabilities.
