Your records. Your perspective.

01

03

FastCue provides tracking and information only, not medical diagnosis, treatment, or advice.

Frequently asked questions

Know what FastCue does before you begin.

Do I need to create an account?

No. In the current release, FastCue works without signup and keeps your fasting, weight, tag, and settings records on this device. The Privacy Policy explains diagnostics, subscriptions, exports, and support data.

How are Insights created?

Free Insights is a fixed sample kept separate from your records. Pro compares eligible personal records and shows available early summaries, evidence counts, and progress when history is limited instead of manufacturing a conclusion.

Does FastCue import weight automatically?

The first-release scope asks you to enter the morning fasted weight you measured, then review its broader trend alongside your own goal.

Can I move or restore my records?

Pro can export readable JSON through the system share sheet and import it again. Restore replaces current local data, so review the warning and keep any needed export first.

Does FastCue provide health advice?

No. FastCue is for tracking and information only. Consult a qualified health professional about whether fasting or a weight-management plan is appropriate for you.

Will notifications always arrive at the exact time?

Notification permission and device settings are required. Timed notifications may arrive late on Android when exact alarms are not allowed. Progress on iPhone depends on Live Activity support in iOS 16.1 or later and device settings. Notifications do not start or end a fast automatically.
