4K Download is a family of desktop apps for downloading video and audio. My work covered app interfaces, new user workflows, monetisation and concepts for new products.
I redesigned five apps for Windows, macOS and Ubuntu. Their interfaces had changed over many years, so I focused on making the screens and controls more consistent.
Desktop applications
The main app window.
YouTube sign-in and download settings.
Video download settings.
Workflows and monetisation
I proposed a built-in browser and a shared control panel. The new features and workflows helped improve activation and retention.
I later continued to work on 4K Download on a project basis and contributed to adding AI post-processing.
Empty states for video and audio.
The library of downloaded media.
New product concepts
By 2020, I had defined demand hypotheses and core features for 4K Tokkit and 4K Image Compressor: who might need them and which problems they should solve. Both products were released later.
The team and design system
4K Download app icons.
Team and process
I built a team of three designers and created a desktop app design system with more than 100 components. This shortened the UI release cycle from about three weeks to ten days.
Later, using Figma and AI tools, I reduced the time needed to prepare graphics from about five days to two.
Website and subscriptions
The 4K Download homepage.
The 4K Video Downloader Plus product page.
The app overview on the website.
Product pages and navigation
In later work on the project, I was responsible for the website and subscriptions as Head of Design: product pages, plan selection, checkout and the website design system.
I redesigned the navigation, app overview and download steps. Together with developers, I built a token-based design system with more than 60 components. This reduced design handoff time by about 35%.
Pricing cards.
The subscription selection page and promotional offer.
Subscriptions and checkout
Subscriptions were a new direction for 4K Download. I worked on product pages, pricing cards, promotional screens and checkout for several apps with users in 190 countries.
Subscription activation and checkout.
A screen for long-term subscribers.
