Veli crypto investing app – portfolio, performance chart and mentor chat screens

UX Strategy & Research

Crypto can feel intimidating to new investors. Veli’s promise is to make better investment decisions easier, with tools, knowledge and real experts in one app.

The app is organised around five tabs, Portfolio, Market, Trade, Strategies and Mentor, so every main task is one tap away. Onboarding stays short: a welcome screen that explains the product, sign up with email or with Facebook, Google or Apple, and the option to leave some steps for later.

Guidance is part of the core experience rather than hidden in a help centre. Updates from the portfolio manager and a personal crypto mentor appear right on the portfolio screen, and the mentor can be reached through an in-app chat or a scheduled call.

Design Approach

A calm, confident interface in Veli blue, built so that numbers are easy to read at a glance.

The portfolio screen shows the total value up front and two ways to look at it: Performance, a line chart with time ranges from 24 hours to a year, and Allocation, a donut chart showing how the money is spread across assets, with the full asset list one tap away.

Every screen was designed in both light and dark mode with the same layout and components, so the app feels consistent whichever theme the user prefers.

Results & Impact

The design covers the whole journey, from the first welcome screen to managing a portfolio and talking to a mentor.

It gave the Veli team one consistent experience for iOS and Android, in both themes, and a clear base for the app published on the App Store and Google Play.

Nemanja brings clarity and polish to complex product work. Across my website, FK Crvena zvezda, and Veli, he was a reliable partner: fast, thoughtful, and consistently easy to work with.
