Q: Do I need an account?
No. This app has no account system. All training data stays on your device.
Q: What training is included?
Three convergence modules: Pencil Push-ups, Brock String, and Jump Convergence, plus a combined “convergence intensifier” session and optional daily reminders.
Q: What should I know before using it?
This is a training aid, not for diagnosis or treatment. Complete an eye / optometric exam and wear proper correction. Stop and seek care if double vision, eye pain, headache, or symptoms worsen. Users under 12 should train with a parent or guardian.
Q: How does the free trial work?
You get 30 days of full access from first launch. The trial is managed on-device by the app; it is not an Apple introductory offer.
Q: What happens after the trial?
You can unlock via a monthly subscription or a one-time lifetime purchase. Entry points: the unlock prompt when starting training, or Settings → Membership / Subscription.
Q: How do I cancel a subscription?
iPhone Settings → Apple ID → Subscriptions, then cancel this app’s subscription. You can also tap Manage Subscription on the unlock screen.
Q: Does lifetime unlock transfer to a new phone?
Yes, with the same Apple ID. Open the app and tap Restore Purchases.
Q: Are effect-record photos uploaded?
No. Photos are stored locally for your own comparison. The app does not read EXIF location data and does not upload photos.
Q: How many sessions per day?
By default, at most two full combo sessions per day to avoid overtraining; follow the limits shown in the app.
