Twino invest

Chili Labs partnered with TWINO to bring their 10+ years of regulated investment experience to the App Store and Google Play.

Through rigorous design and mobile app development, we engineered a high-performance platform for modern investors. The new app provides a frictionless way to:
• Access and trade asset-backed securities
• Manage complex investment portfolios in real time
• Use automated investing strategies

About the Company / Project

TWINO is a leading European investment platform dedicated to making asset-backed securities and P2P lending accessible to everyone. Our team designed and developed Flutter applications for both Android and iOS from the ground up. By prioritising security, clarity, and ease of use, we transformed a complex investment environment into a streamlined mobile experience that empowers users to manage their portfolios anytime, anywhere.

Project Tasks

Main Idea

The core objective was to translate TWINO’s decade long expertise in the European fintech market into a mobile environment. As the company shifted its focus toward Asset-Backed Securities (ABS) and high liquidity products like FLEXI, they needed a mobile presence that matched their status as a regulated, licensed investment firm.

Define Issues / Problems

Web-Only solution
Until now, the services were only available on the website and limiting user engagement on mobile.

Information Overload
Displaying complex financial data and real-time portfolio updates in a way that feels clear and easy to navigate on a small screen.
Holistic UI/UX Design
We created a mobile-first design system tailored for iOS and Android, transforming complex financial data into clear, intuitive interfaces focused on usability and trust.
Agile Flutter Development
Using Flutter’s cross-platform capabilities, we accelerated development while ensuring both iOS and Android users received the same premium experience simultaneously.
Future-Ready Architecture
We built the app with scalability in mind, allowing TWINO to quickly roll out new financial products (like FLEXI) to their mobile users as soon as they are ready.

What Was Done

From idea to market ready product

To bring the Twino Invest mobile experience to life, we established a high transparency workflow that turned TWINO's vision into a functional, market ready product. Our process focused on speed, precision, and continuous alignment.
Platform Audit & Conceptualisation
We began by deep-diving into the existing TWINO web platform to understand its core logic. Our goal was to translate that complex investment data into a mobile format that retained the brand’s identity while optimising it for smaller screens and touch interactions.

Full Cycle UI/UX Design
From initial wireframes to the final polished interface, we designed every screen for both iOS and Android. This included creating a custom design system for the app and a full set of store assets (screenshots and graphics) to ensure a professional first impression on the App Store and Google Play.

Flutter Mobile App Development
We developed the application using the Flutter framework, ensuring a unified codebase that delivered native performance and a consistent look across both platforms simultaneously.

Weekly Demo Feedback Loop
Transparency was at the heart of our collaboration. Chili Labs held weekly demos with the TWINO team, showcasing tangible progress and gathering immediate feedback. This allowed us to stay perfectly aligned with their expectations and the project's evolving needs.

Agile Iteration & Refinement
We didn't wait until the end to polish. If a feature felt "off" or a flow didn't feel intuitive once implemented, we made rapid updates. This iterative "test-and-tweak" approach ensured that the final product felt natural and user friendly from day one.

Fresh & Engaging Design
For Twino Invest, the design challenge was to strike a perfect balance: it needed to feel as trustworthy as a traditional bank, yet as innovative and "snappy" as a modern fintech disruptor. Moving elements from web to mobile wasn’t an option; we reimagined the entire visual journey.

The Foundation: Respecting the DNA
We started with the TWINO Brandbook as our North Star. By utilizing their established color palette, typography, and core identity, we ensured that long-time investors would feel immediately at home. We took the functional logic of the web platform and simplified it for mobile, removing unnecessary complexity and focusing on clarity and speed.

Attention to Security

In the fintech sector, a beautiful interface means nothing without ironclad protection. Since Twino Invest is a regulated investment brokerage firm, we had to ensure the app met the highest European security standards without compromising the user experience. We implemented a multi-layered security architecture designed to keep assets safe and give investors peace of mind.
A Layered Defense Strategy
Chili Labs team built a comprehensive defense system that protects the user at every touchpoint:

• Robust Password Protection: The first line of defense, requiring strong, unique credentials to ensure account integrity from the start.
• Custom PIN Access: For quick yet secure sessions, we implemented a personalized PIN code. This allows users to check their portfolios on the go without re-entering complex passwords every time.
• Seamless Biometrics: Using the latest hardware capabilities of iOS and Android, we integrated FaceID and TouchID. This provides a login experience that is both high-speed and high-security.
• 2FA (Two-Factor Authentication): To prevent unauthorised access, we integrated 2FA via authenticator apps. This ensures that only the rightful owner can perform sensitive actions or log in from new devices.

Regulated & Reliable
By combining security features with encrypted data transmission, we ensured the mobile app fully complies with strict EU financial regulations. The result is a secure platform where users can focus on growing their investments. Their data and funds remain protected by industry-leading security standards.

The Result: A New Chapter for TWINO

The successful launch of the TWINO Invest mobile app marked an important step for the brand. By delivering a high-performance and fully functional MVP for both iOS and Android, we enabled TWINO users to manage their investment strategies wherever they go.

Key Outcomes

Dual-Platform Launch
Using Flutter, we delivered releases on the App Store and Google Play at the same time, ensuring no part of the user base was left behind.

Operational MVP
While this version represents a "Minimum Viable Product," it is a robust, production ready tool that handles real time financial transactions and regulated asset management with zero compromise on stability.

Foundational Success
We established a clean and scalable codebase alongside a consistent mobile design system. This gives TWINO a strong foundation for future updates, user feedback gathering and new feature releases.
