About

Femmflo

Read full description

Femmflo is a proprietary AI women’s health platform that connects hormones, mental wellbeing, and lab data into personalised, guided care plans. The app is designed to move beyond symptom tracking by helping women understand how hormonal patterns, lab results, and psychological wellbeing interact over time. Instead of fragmented information, Femmflo brings these data points into one intelligent system that surfaces meaningful insights and next steps. Users begin with a guided onboarding experience that captures health, hormonal, and lifestyle information. Ongoing check-ins track symptoms, mood, and overall wellbeing, building a personalised health profile. Where appropriate, users are guided to complete relevant lab tests through trusted partners, with results securely uploaded into the app. At the centre of Femmflo is Gabi, the AI assistant that analyses lab data alongside check-ins and health history to generate clear, lifestyle-led care guidance. This support is designed to complement, not replace, medical care. When clinical input is needed, users are guided to consult trusted doctors, with outcomes feeding back into the platform (with consent) to support a seamless, continuous care journey. Femmflo gives women clarity, context, and control over their health.

About

Period Tracker

Features
Read full description

Bloom tells you when your next period is coming, when your fertile window opens, and which phase you are in today β€” and keeps every answer on your phone, where only you can see it. Most period trackers ask for an account, an email, and permission to study your cycle. Bloom asks for nothing. Log your flow in a tap, and Bloom learns your rhythm from your own history, predicts the month ahead, and surfaces the patterns in your symptoms and mood. No sign-up, no cloud, no ads. WHAT YOU GET β€’ Know the day your next period is due, with a live countdown from your own average cycle β€’ See your fertile window and ovulation day in advance, so the month never surprises you β€’ Understand which phase you are in right now with a calm phase ring and a one-line guide β€’ Spot the symptoms and moods that return every cycle, ranked by how often they show up β€’ Learn how regular you really are: average cycle, average period, and a full cycle history β€’ Get a gentle heads-up the morning your period or fertile window is predicted to begin PERFECT FOR β€’ Anyone who wants to stop guessing when their period will start β€’ Planning ahead for trips, workouts, and big days around your cycle β€’ Trying to conceive and wanting a clear view of the fertile window β€’ People who refuse to hand their cycle data to an app company WHY NOT JUST USE A BIG-NAME TRACKER? The well-known apps are built around accounts, community feeds, and data collection. Bloom is built around a single calendar, a quick log, and a clean insights page. Open it, log the day, see what is next, and close it. Your history stays on your device, and the app stays out of your way. PRIVATE BY DEFAULT Everything you log β€” flow, symptoms, mood, notes β€” is stored only on your iPhone. There is no account to create, no server that receives your entries, and no analytics tracking. Reminders are scheduled on-device too. You can erase everything with one tap in Settings. Bloom is a personal tracking tool, not a medical device. Predictions are estimates based on your logged history and should not be used for contraception or medical decisions. Always consult a qualified healthcare provider for medical concerns. FULL ACCESS Bloom is a premium app. Choose a weekly or yearly auto-renewing subscription, or a one-time lifetime purchase, to unlock unlimited cycle history, predictions, fertile window and ovulation forecasts, and full symptom, mood and flow insights. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Payment is charged to your Apple ID account at confirmation of purchase. Manage or cancel any time in your App Store account settings. Download Bloom and log today's flow β€” your first prediction appears the moment you do.
