FocusField — Work Smarter
Deep Work Timer & HRV Insights
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
Find your focus zone with biometric feedback. FocusField pairs Pomodoro timers with HRV data to show when you're truly focused — and when to take a break.
By pairing Apple Watch heart rate variability with real-time noise, light and pressure readings, it builds a personal map of where and when you do your deepest work. No manual logging. No journaling. Just evidence.
• FOCUS SCORE — A personal 0–100 score for every work session, weighted by HRV stability, session length, focus onset speed and environmental conditions. Normalised to YOUR baseline, not a universal benchmark.
• FOCUS WEATHER — Location cards show your average score, conditions and best time-of-day window for each venue you visit. Home Office: 84 Excellent. Coffee shop: 61, try afternoons.
• PASSIVE SENSING — Start a session and forget about it. FocusField reads HRV from your Watch, ambient noise (dB only, no audio stored), barometric pressure and GPS — all silently in the background.
• LOCATION INTELLIGENCE — GPS coordinates are clustered into named venues. Each accumulates a focus profile: noise range, best hours, session count, average score.
• SESSION REPLAY — After each session, see how your HRV evolved, which noise events correlated with focus drops, and what conditions produced your peaks.
• APPLE WATCH — Companion app with session controls and live focus score. Watch complication shows your current state at a glance.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
The app is built around a dark design, but menus, pickers and share sheets were still following your phone's light setting and flashing bright against it. Everything now stays dark, so the whole app looks like one piece.
