Focus Sentry
A focus tracking web app exploring lightweight real time signals and feedback loops, aimed at helping users reflect on attention patterns without overcomplicating the experience.
Problem
Focus is hard to measure without turning it into a surveillance project.
Many tools overwhelm users with metrics instead of useful feedback.
Real time systems need to be lightweight to feel usable.
Solution
A simple loop: detect signals, summarize them, and present a clear reflection.
Designed around usability first, with signal quality improving iteratively.
Kept it fast and minimal so it feels like a helper, not a monitor.
Key Engineering Decisions
Prioritized low friction UX over maximal model complexity.
Focused on practical feedback loops, not vanity accuracy.
Built the system to be extendable as signals and features evolve.
What I Learned
Good product feedback beats perfect measurements.
Real time constraints force better engineering decisions.
