Only for iPhone

Track food, sleep, mood, activity, cycle, and wearable data. Krissi connects every signal and surfaces the patterns shaping how you feel.
Krissi is a holistic personal health companion. She tracks the dimensions of how you feel - food, sleep, mood, activity, cycle, gut health, and your wearable data - and uses AI to surface the patterns shaping all of it to give you meaningful, personalized insights.
Krissi is a wellness companion, not a medical device. She doesn't diagnose, treat, or prevent any condition. But she will help you understand your body better than you have before.
THE WHOLE PICTURE, NOT A SLICE
Most trackers show you one dimension. Krissi brings every signal together, because your body doesn't work in isolated pieces. Sleep affects mood. Stress affects gut. Cycle affects energy. Krissi treats your body the way it actually is: connected.
WHAT KRISSI UNDERSTANDS
Food and meals, with intelligent gut-health guidance
Sleep: duration and quality
Mood and the things shaping it
Movement and exercise
Menstrual cycle and hormonal patterns
Caffeine, alcohol, and other substances
Gut and digestive patterns
Weight
Wearable data: HRV, resting heart rate, body temperature, blood oxygen, blood glucose, and more
AI THAT READS BETWEEN THE LINES
Logging is only useful if someone reads it back to you. Krissi's AI cross-references everything you track, then tells you what she's noticing: the foods that affect your sleep, the cycle phases that shift your energy, the patterns you couldn't see on your own.
Three AI-powered ways to log and learn: voice meal logging (just say what you ate), photo meal logging (snap your plate), and a conversational assistant that knows your full history.
WORKS WITH APPLE HEALTH
Krissi integrates with Apple Health, so the wearables and health apps you already use just work. Your data flows in automatically - no manual entry needed for the signals your devices already track.
YOUR HEALTH DATA LIVES ON YOUR DEVICE
There's no Krissi account, no cloud sync, and no Foddies-side database holding your records. Everything you log is stored locally on your device. If you choose to use Krissi's insight features - voice logging, photo logging, or asking Krissi a question - your health data is sent to Anthropic, the company behind the language model Krissi uses. How Anthropic handles that data is governed by their privacy policy. If you never use these features, no data ever leaves your device.
