Aether is a personal visual instrument for iPhone and iPad, provided as-is for your own use.
Aether renders the centers of gravity you name as an abstract field that lives on your Home Screen, Lock Screen and StandBy. It is a visual instrument. It shows no charts, trends or insight reports; it does not measure, interpret or diagnose any mental or physical state; and it is not a health, therapy or diagnostic tool. Do not use it as the basis for any medical or safety-critical decision.
Aether Premium is offered as an auto-renewing monthly subscription ($4.99/month) or annual subscription ($39.99/year, with a 7-day free trial for new subscribers), and as a one-time Lifetime purchase ($79.99, family-shareable), all billed through your Apple ID. Subscriptions renew unless cancelled at least 24 hours before the current period ends; manage or cancel them in Settings → Apple ID → Subscriptions. The free tier remains fully functional regardless of any purchase.
The centers of gravity you name and the fields you create are yours and stay on your device. Aether claims no rights over them.
