The OTP step is where these apps quietly leak or annoy. On Android the SMS Retriever API fills the code without READ_SMS, and a resend timer with backoff stops users hammering it. Worth checking sign-in errors too, a distinct "no account" message hands an attacker a list of valid numbers.
I put together some of the fintech and product design projects we’ve done at the agency.
Great Work!
Complex FinTech data shouldn’t feel like a spreadsheet.
Most investment apps suffer from two major problems: either the UI is so cluttered that users drop off, or the developer struggles to render real-time interactive charts without frame drops.
As a Mobile App Developer who crafts clean UI/UX, here is how I designed and engineered Aivest—an AI-powered investment & portfolio simulation platform:
🔹 The Product Challenge: Users need to simulate financial futures and track live asset rebalancing without getting overwhelmed by raw numbers.
🔹 The UX & Visual Polish: Designed a high-contrast dark theme using neon accents (#D8FF00) and the clean geometric typeface Lufga to make key data points instantly scannable.
🔹 The Dev Architecture: Engineered custom interactive slider components, dynamic scenario simulations, and smooth 60fps graph renders with optimized state management for real-time portfolio updates.
Great FinTech products require pixel-perfect design built on high-performance, responsive code. 📈⚡
If you are building a FinTech or AI product, let’s build something users actually love using.
