Troubleshooting
- Requirements: Cexi runs on iPhone with a recent version of iOS. Keep iOS and the app updated for the best experience.
- Coach won't respond: the coach needs an internet connection. Check connectivity, then try again.
- Health data missing: confirm permissions (see above) and that the data exists in the Health app.
- Apple Watch heart rate: keep your iPhone nearby and ensure the Watch is unlocked and paired.
- Still stuck: reinstalling keeps your synced data; email us your device model, iOS version, and app version.
Service status
See the public service status page for current notices. Sync and account features depend on Supabase, and coaching depends on our configured AI service. If either provider has an outage, those features may be briefly unavailable while your on-device training data keeps working.
FAQ
Is Cexi a medical app?
No. Cexi is for general fitness and wellness guidance only. It is not a medical device and does not provide medical advice.
Does the AI coach replace a trainer or doctor?
No. Coach answers are informational, may be incomplete or inaccurate, and are not a substitute for a professional.
What health data does Cexi access?
Only the categories you approve in Apple Health: typically sleep, HRV, resting heart rate, and activity metrics used for recovery context. Access is optional and revocable.
Where does my data live?
The training-intelligence models run on your device. Cloud sync (Supabase) backs up your account and history. Coach and workout design send limited context over the network for AI inference. See the Privacy Policy.
Are there subscriptions?
No. Cexi is free, with no in-app purchases and no subscriptions.
