LEEG
Career OS
An end-to-end redesign that revealed one problem. Users couldn't understand what they were doing or why it mattered
A two-person UX team redesigning a career development app from the ground up — competitive analysis, usability testing across 11 participants, hi-fi prototype, and a full developer handoff.
What Leeg needs
A redesigned daily engagement flow that keeps users coming back consistently — with clear information architecture, an onboarding experience that sets the right expectations, and a handoff package that a development team can actually build from.
What users need
To understand what they're doing and why it matters. To feel like their daily actions connect to real career growth. To not be confused by terminology, navigation, or data that has no context attached to it.
How I did it
ITERATIONS
What i changed
ITERATION 01 - NAVIGATION
We restructured the bottom nav from 4 tabs to 5 and removed redundant icon buttons after A/B testing confirmed both changes reduced confusion


✗ Goals buried inside Profile — no dedicated tab
✗ Icon buttons for Boosts, Goals, Reflection redundant with nav tabs and Today cards
✗ Users unsure where to find goal progress
✓ Goals gets its own dedicated tab — 5-tab nav
✓ Redundant icon buttons removed — cleaner, less cognitive load
✓ Both changes validated through A/B testing
Insight
A/B testing revealed two things: users couldn't locate their goals without a dedicated tab, and the icon buttons for Boosts, Goals, and Reflection were redundant — those features already had cards on the Today page and their own tabs in the nav. Removing the buttons reduced clutter and the added Goals tab gave users a clear, persistent home for their progress.
ITERATION 02 - BOOST CONTENT STRUCTURE
We added a single line of context to the Boost entry point after 100% of participants couldn't engage without an explanation


✗ No context for what a Boost is before entering
✗ Users arrived at Hook/Core/Do/Takeaway without understanding the purpose
✓ Subtitle added — "A quick, focused lesson to help you build one skill at a time"
✓ Users now understand what they're doing before engaging with the content
Insight
Even with Hook, Core, Do, and Takeaway already color coded and visually differentiated, 100% of participants still needed the Boost explained before they could engage. The fix wasn't restructuring the content — it was adding a single line of context at the entry point. One sentence changed how users approached everything below it.
ITERATION 03 - TERMINOLOGY EXPLAINERS
We added plain-language tooltip overlays after Boost, True North, Fading, and Evidence were flagged as unclear in both testing rounds



✗ "True North" — no participant could explain it
✗ "Fading" and "Evidence" equally unclear
✓ Plain-language definitions on first encounter
✓ Tooltips triggered by info icon tap
Insight
Boost, True North, Fading, and Evidence were flagged as unclear across both rounds. Info icons were added next to every key term triggering tooltip overlays with plain-language definitions — so users spend mental energy on their growth, not decoding the interface.
ITERATION 04 - INSIGHTS PAGE
We redesigned the insights page to surface actionable metrics first after 73% of participants found it overwhelming on first view


✗ 73% found it overwhelming on first view
✗ Metrics unexplained — no "so what" context
✓ Most actionable metrics lead the page
✓ Fewer competing tabs, clearer hierarchy
Insight
73% of participants found the insights page overwhelming on first view. The layout was simplified to lead with the most actionable metrics — giving users clearer next steps tied to their actual growth patterns rather than presenting every data point at once.
