Track hot flashes, periods, HRT, sleep, and mood. Export a clean report for your doctor. That's it. HotFlash is a private menopause journal built for women who are tired of subscription apps that demand an account, store your symptom data in the cloud, and charge a yearly fee for what should be a simple log. No subscriptions. No account. No cloud. No ads. Pay once, log forever. ONE-TAP HOT FLASH LOG Tap once to log a hot flash with the current time. Hold to start a Live Activity timer that runs from the Lock Screen โ no need to dig through menus when it starts. Adjust severity, add triggers, and capture night sweats automatically. PERIMENOPAUSE-AWARE CYCLE TRACKING HotFlash counts up โ days since your last period โ and never pretends to predict an irregular cycle. Your cycle history shows your real pattern without false forecasts. HRT & MEDICATION LOG Patches, gels, oral estrogen, progesterone, vaginal estrogen, testosterone, and non-hormonal options โ log doses, set optional reminders, and track compliance. No prefilled drug database. You add what you actually take. SLEEP & MOOD QUICK CAPTURE A single morning log captures sleep quality, hours slept, wake-ups, night sweats, and morning mood. A REPORT FOR YOUR DOCTOR Export a clean PDF with hot flash frequency, time-of-day patterns, HRT compliance, sleep, mood, and your own notes. Take it to your appointment. No more "I think it's been getting worse" โ you'll have the data. PRIVATE BY DESIGN No account. No cloud. No analytics. No third-party SDKs. Optional Face ID lock for extra privacy. Your menopause data never leaves your device. Built for women who are tired of paying every year for features that should be a one-time purchase. If you've ever closed a "wellness" app because it asked you to sign in to track your own body, this app is for you. NOT MEDICAL ADVICE HotFlash is a personal log, not a medical device. It does not provide diagnosis or treatment recommendations. Always consult your healthcare provider about menopausal symptoms and HRT.
