## What is Hemogoblin?

Hemogoblin tracks your period, symptoms and moods, finds your patterns, and keeps every bit of it on your devices. No account. No servers. No ads. Nobody reads your cycle but you.

TODAY AT A GLANCE
• Where you are in your cycle, when the next period is likely, and what usually shows up around now
• Reminders before your period and on the day, with a discreet mode that keeps your lock screen boring

LOG IN SECONDS
• Flow, spotting, symptoms, mood, pain and notes, for today or any day
• Press and hold a symptom to rate how bad it is
• Log from your Apple Watch, or start from a widget, Control Center or Siri

INSIGHTS WITH RECEIPTS
• Your usual cycle and period length, and how much they vary
• Patterns like "cravings 3 days before", with every cycle behind them
• Tap any bar, row or night for the detail
• Each cycle against your usual, plus flow and pain over time
• How close past estimates actually landed

BODY SIGNALS, IF YOU WANT THEM
• Bring in sleeping temperature, basal temperature, resting heart rate and ovulation tests from Apple Health
• See each cycle's temperature shift, and how the days after it hold steady

PRIVATE BY DESIGN
• Everything stays on your iPhone and Apple Watch, out of iCloud and out of device backups
• Face ID lock, and the app hides itself in the app switcher
• Encrypted backups you control, plus CSV export
• Optional two-way link with Apple Health

ALSO
• iPhone, iPad and Apple Watch, with widgets and complications
• Moon phases on the calendar, for fun and profit
• Curiosities 

Every estimate follows published rules: chungus-actual.github.io/hemogoblin/estimates

Hemogoblin estimates; it doesn't diagnose. It isn't birth control and isn't a medical device. Best used in partnership with a healthcare professional.
