Notes, patterns, and care
Keep the whole story together.
FND Sentinel 2 brings a playful watch companion and a calm phone workspace for check-ins, events, personal notes, a care plan, and appointment preparation. The watch can save records offline and transfer them when the paired phone reconnects.
Private by design: No account. No ads. No analytics. No tracking. No developer server. Your Health data, episode records, and app activity are not sent to William Evans. Your devices use Apple WatchConnectivity to exchange records. You choose when to share reports or open external information resources.
Support
Connect Health, learn the watch controls, troubleshoot syncing, and contact support.
Privacy
See how Health data, check-ins, care plans, offline queues, backups, exports, and deletion are handled.
Method and limits
Understand the personal baseline, pattern score, retrospective learning, and known uncertainty.
Important: FND Sentinel is a personal pattern-tracking aid, not a medical device, diagnosis, treatment, emergency service, or reliable predictor. Expect missed events and false alerts. Never use it for safety-critical decisions or instead of a clinician-approved care plan. If someone may be in danger, contact local emergency services.
