About

Glasyn

Read full description

Glasyn is a calm, private diary for hot flashes, with an optional daily check-in for how each day felt. Log a hot flash in two taps, watch your own patterns take shape, and walk into your next appointment with a clear summary to share. WHAT YOU CAN DO - Log in two taps. Tap the button, choose how strong it was, and you are done. Add a note, a trigger, or the time of day only if you want to. - See your patterns. A simple calendar and insights show how often hot flashes happen, day versus night, and how many woke you up. - Notice what tends to come first. Tag triggers like caffeine, alcohol, stress, or a warm room and see which ones show up most. - Keep a night record. Mark episodes that happened at night and the ones that woke you, so sleep is part of the picture. - Note how the day felt. An optional daily check-in records mood, sleep, joint or muscle ache, and foggy thinking, in your own words, so the picture is more than hot flashes alone. MADE FOR THE CONVERSATION WITH YOUR DOCTOR Appointments are short. Glasyn turns weeks of entries into one clear page you can hand to your clinician, as a PDF, with a CSV of the raw data if they want the detail. It is organized, easy to read, and ready to discuss. PRIVATE BY DESIGN - Everything stays on your iPhone. Nothing is uploaded. - No account to create. No sign-up, no email. - No ads, no tracking, and your information is never sold or shared. SIMPLE ENOUGH TO ACTUALLY USE Large text, plain words, and one clear action on every screen. Built to be quick when you are warm and uncomfortable, not one more thing to manage. GLASYN PLUS Logging is always free and unlimited. Glasyn Plus unlocks the doctor report and full insights. Choose monthly ($4.99, 7-day free trial), yearly ($39.99, 14-day free trial), or a one-time lifetime purchase ($59.99). Manage or cancel any time in your Apple ID settings. Glasyn is a personal wellness diary. It does not provide medical advice, diagnosis, or treatment, and it does not describe menopausal status. Always talk with a qualified healthcare provider about your health. Glasyn Plus is an auto-renewable subscription (or a one-time Lifetime purchase). Payment is charged to your Apple ID at confirmation. Subscriptions renew automatically unless cancelled at least 24 hours before the period ends; manage or cancel in your Apple ID settings.
