Notice what's happening before it decides for you.
Interoceptive training for Apple Watch + iPhone
Your body knows before you do.
Interoception — awareness of what's happening inside your body — is trainable. Improve it, and you catch emotions earlier: before the spiral, before the reaction. Earlier noticing is where the choice lives.
No product trains this skill. No product measures the change.

Claude streams contemplative response
The metric no one else measures
Shorter lead time means noticing sooner — more moments where you can choose to respond rather than react. If the reduction tracks MAIA-2 improvement, that's a peer-reviewable finding: the first objective measure of interoceptive skill gain.
Three trust paths, one protocol.
Biometric data never leaves the Watch-iPhone pair.
Raw data stays on the device; only relative descriptors transmitted.
Cloud data pulled to phone, processed locally, never re-uploaded.
Three categories. None connect all three layers.

WHOOP reads only WHOOP. Oura reads only Oura. Notice reads all three — and builds a unified awareness layer on top.
Core: $80/yr (AI reflection limited). Full: $149–199/yr (unlimited AI, multi-device). Positioned between meditation apps (~$70) and health trackers (~$200).
On-device personalization + an app that grows with the user.
