One navigation system for a five-era app
A single web app-shell — sidebar, header, embedded clock-in, theme system — replacing navigation accreted across five product eras, shipped as a migration, not a cutover.
Problem
Navigation had accreted across five product eras — five mental models fighting inside one app.
Outcome
MeasuredClock Now held ~14k weekly users at ~89% completion through the migration, flat across 52 weeks.
The problem
Five product eras, five navigation paradigms, one app. Every new feature had added a new way to move around instead of a place to live.
Constraints & context
Decisions & tradeoffs
Outcome
The riskiest number to hold: Clock Now — the single most-used action in the product — kept ~14k weekly users at ~89% completion through the entire migration, flat across 52 weeks (Amplitude-verified). A redesign that users didn't have to relearn.
