FocusField
Read full descriptionHide full description
Find your focus zone with biometric feedback. FocusField pairs Pomodoro timers with HRV data to show when you're truly focused β 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. β’ FOCUS SCORE β A personal 0β100 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. β’ FOCUS WEATHER β 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. β’ PASSIVE SENSING β Start a session and forget about it. FocusField reads HRV from your Watch, ambient noise (dB only, no audio stored), barometric pressure and GPS β all silently in the background. β’ LOCATION INTELLIGENCE β GPS coordinates are clustered into named venues. Each accumulates a focus profile: noise range, best hours, session count, average score. β’ SESSION REPLAY β After each session, see how your HRV evolved, which noise events correlated with focus drops, and what conditions produced your peaks. β’ APPLE WATCH β Companion app with session controls and live focus score. Watch complication shows your current state at a glance. FOCUSFIELD PRO Unlock the full intelligence layer: β’ Unlimited session history and locations β’ AI-powered recommendations ("You focus 34% better before 10am") β’ Watch face complication β’ Focus Weather forecast β’ CSV export Monthly Β£2.99 or Annual Β£19.99 (best value).
