Flashpoint
Log a hot flash in three seconds — then find out what actually set it off
Tap for a day flash, hold for a night sweat, tag what was true that day, and Flashpoint runs the lift correlation right here in your browser to name your top three triggers. Plus a 24-hour clock heatmap and a raw CSV for your gynecologist. Free, no account.

What you can do in Flashpoint on the web
Three-second logging
One big button: tap for a day flash, press and hold for a night sweat. Two buttons under it ask for severity 1–5 when you want to be precise.
Daily trigger tagging
Caffeine, alcohol, spicy food, sleep under six hours, warm room, HRT taken late, period day, plus a 0–5 stress score — one row saved per calendar day.
Your top three triggers
The same lift maths as the iPhone app: average flashes on trigger-present days versus trigger-absent days across 28 days, ranked by absolute lift, with the with/without bars and the day counts behind every number.
24-hour clock heatmap
Twenty-four wedges around a clock face tinted by flash count, plus hour totals and a day-versus-night split — so a 3 a.m. cluster is impossible to miss.
Raw CSV export
Every flash and every trigger row downloads as plain CSV you can hand to your clinician. No email signup, no upload.
Nothing leaves the tab
The correlation runs in your browser and the log is stored locally — no account, no subscription, no employer paywall.
