Your watch doesn't know how you feel. Your ring doesn't know what you ate. You're more than a data point. Krissi puts it all together.
Free to start · No account needed · Android & iOS
Your wearable data comes in automatically. Log whatever you like on top: food, mood, sleep, exercise, cycle and more. Krissi brings it together to show you what's really going on.
If it syncs with Apple Health or Health Connect, it works with Krissi.
From your day at a glance to the patterns underneath.
Today
Everything from your day in one place: how you slept, your HRV and resting heart rate, steps, exercise, what you ate, how you're feeling. No digging through separate apps.
Trends
Your health timeline puts every dimension side by side across the week, so you can see how one thing moved when another did, and whether you're tracking better or worse than usual.
Connections
Krissi lays out the patterns she's found across your logged days, each one rated by how strong the link is, and double-checked against other things that could explain it.
Krissi answers questions about your health, using your own data.
Krissi surfaces patterns from your data, not medical advice.
Your activity level is genuinely impressive, and your recovery metrics suggest your body is mostly handling the load well, but there are some patterns worth keeping an eye on.
Your sleep is the headline story here, and the wild swings between nights are what stand out most.
The gut-brain connection is real, and your sleep data suggests your nervous system may already be under more strain than you realize.
Asking Krissi uses AI to analyze your data. Read how that's handled in our privacy policy.
Get started
Krissi is free to start. Available now on Android and iOS.
Free to start · No account needed · Android & iOS
Everything you log is stored locally - no account, no cloud sync, no Foddies-side database. Krissi does her pattern analysis right on your device. AI is only used for a few specific features - Ask Krissi, plus voice and photo meal logging - and only at the moment you use them, when your data is sent to Anthropic to generate a response (governed by their privacy policy). If you don't use those features, nothing ever leaves your phone.

Krissi is a holistic personal health companion developed by Foddies, Inc. We built Krissi with privacy at its core: your health data is sensitive and personal, and we treat it that way. This policy explains exactly what data Krissi handles, where it lives, and what happens when you use the app's AI features.
Krissi is operated by Foddies, Inc ("we", "us", "our"), the data controller for the purposes of UK GDPR and EU GDPR. Our registered address is 325 N St Paul Street, Suite 3100, Dallas, Texas 75201, United States. You can reach us at info@foddies.com for any questions about this policy or your data.
When you use Krissi, you may choose to log: food entries and meal photos, symptoms, mood and mood drivers, sleep, exercise, bowel movements (Bristol stool scale), weight, menstrual cycle phase, substances (caffeine, alcohol, nicotine), gut score check-ins, and an optional profile (first name, age, sex, conditions, medications). Everything is optional. You decide what to track.
If you grant Krissi access to Google Health Connect (Android) or Apple Health (iOS), Krissi reads the following data types from your wearables and connected health apps to provide pattern analysis and personalized insights:
Each data type is read only to display it inside Krissi and to feed Krissi's pattern analysis. You can revoke permissions at any time through the Health Connect app (Android) or Settings > Privacy & Security > Health (iOS).
All data (what you log directly and what Krissi reads from Health Connect or Apple Health) is stored locally on your device. There is no Krissi account, no cloud sync, and no Foddies-side database holding your records.
If you choose to use any of the AI features (described below) your health data will be transmitted to a third-party processor only at the moment you use them.
Krissi has three AI-powered features: voice meal logging, photo meal logging, and the Krissi conversational assistant. If you choose to use any of them, your health data is transmitted to Anthropic, the company providing the underlying AI model (Claude). For voice and photo logging, this includes the food database and your transcript or photo. For the conversational assistant, this includes a comprehensive snapshot of your recent health data - food and symptom entries, sleep, exercise, mood, bowel movements, wearable biometrics, supplements, and any profile details you have entered.
How Anthropic processes, retains, and handles this data is governed by Anthropic's privacy policy.
If you do not use the AI features, no data ever leaves your device through Krissi.
Krissi uses PostHog to capture pseudonymous product analytics: which features are used, how long onboarding takes, whether features are working correctly. Each device is identified by a randomly-generated ID created on first launch; this ID is not linked to your name, email, or any other identifying information.
Under UK GDPR and EU GDPR, our legal basis for processing your data is:
Under UK GDPR and EU GDPR, you have the right to access, correct, delete, or export your personal data, and to object to or restrict processing. Because Krissi stores your data on your device, you can exercise these rights directly: open the app to view or edit any entry, delete entries individually, or clear all data via your phone's settings or by uninstalling the app. For specific questions or formal requests, contact us at info@foddies.com.
UK and EU users also have the right to lodge a complaint with their local data protection authority (in the UK, the Information Commissioner's Office at ico.org.uk).
Because there is no Krissi account, deletion is straightforward. Uninstalling Krissi removes all of your logged data from your device. Alternatively, you can clear the app's storage from your phone's Settings (Settings → Apps → Krissi → Storage → Clear data). Both actions are permanent and cannot be undone. There is no backup on our end to restore from.
Krissi is not intended for use by anyone under 18. We do not knowingly collect data from anyone under 18. If you believe someone under 18 has used Krissi, please contact us at info@foddies.com.
We may update this privacy policy from time to time. Any changes will be reflected on this page with an updated date at the top. For material changes (for example, new categories of data being processed, or a new third-party processor) we will surface the change inside the app so you have a chance to review before continuing to use Krissi.
For any questions about this privacy policy or how Krissi handles your data, please contact us at info@foddies.com.
