Is Bloom really free? ▼
Yes. Full cycle tracking, pregnancy planning, pregnancy mode, AI chat (with message limits), insights, and all core features are free. Invite friends to earn more Lily messages — 5 referrals = 15 messages, 25 referrals = unlimited.
Do I need to create an account? ▼
No. Bloom works entirely offline with local storage on your device. No account, no email, no phone number required. Create an account only if you want cloud sync across multiple devices.
How accurate are the predictions? ▼
After 6+ logged cycles, Bloom achieves 85-90% accuracy within ±2 days. Every prediction shows a confidence score so you always know how reliable the forecast is. The ML model uses weighted moving averages and trend detection — not static 28-day math.
How does pregnancy planning work? ▼
Log your BBT (basal body temperature), cervical mucus type, and OPK (ovulation predictor kit) results daily. Bloom calculates your daily conception probability using a Bayesian model based on the Wilcox 1995 fertility study. It predicts your fertile window, detects ovulation via thermal shift, and generates a conception report at the end of each cycle showing how well your timing aligned.
How do I switch to pregnancy mode? ▼
Go to Pregnancy Planning or Profile → tap "I'm Pregnant" → enter your last menstrual period (LMP) date. Bloom calculates your due date (280 days from LMP) and transforms into a full pregnancy tracker with gestational age, weekly milestones, symptom logging, and trimester-specific guidance.
Can I switch back from pregnancy mode? ▼
Yes. You can disable pregnancy mode anytime in your Profile settings and return to regular cycle tracking. Your cycle history is preserved.
Is my data safe? ▼
Your data is stored on your device by default — it never leaves your phone unless you explicitly enable cloud sync. If you do enable cloud, data is encrypted in transit and at rest. Bloom never sells, shares, or uses your health data for advertising. Couple mode uses end-to-end encryption — the server cannot read shared data.
What is Couple Mode? ▼
Couple Mode lets you share selected cycle/fertility data with your partner. Pair with an 8-character code, choose what to share (fertile window, mood, cycle summary, symptoms), and all shared data is end-to-end encrypted. The server only sees encrypted blobs. Unpair anytime — all shared data is permanently deleted.
Who is Lily? ▼
Lily is Bloom's AI wellness companion powered by GPT-4o. She has three expert roles: gynaecological guide (OB-GYN knowledge), mental health coach (anxiety, mood, stress), and productivity advisor (cycle-synced work optimization). Every response is personalized to your current cycle day, phase, moods, symptoms, or pregnancy week.
What languages does Bloom support? ▼
English and Hindi (695+ translation keys each). Choose your language during onboarding or change anytime in settings. More languages are planned.
Does Bloom replace my doctor? ▼
No. Bloom is an informational tool — not a medical device and not a substitute for professional medical advice, diagnosis, or treatment. Always consult your healthcare provider for medical decisions, especially during pregnancy or if you notice unusual symptoms.
Is Bloom available on iOS and Android? ▼
Bloom is live on Android via Google Play. The iOS version is fully built and ready — it can be launched on the App Store immediately. Both versions have identical features.
