The Question Coach is unavailable

  1. Check that your iPhone or iPad supports Apple Intelligence.
  2. Turn on Apple Intelligence in the Settings app under Apple Intelligence & Siri.
  3. Give the on-device model time to download. Keeping the device on Wi-Fi and charging helps.
  4. Open a lesson or question and tap Ask about this lesson or Ask about this question again.

One conversation is free. Full Access unlocks unlimited conversations. Every other feature works without Apple Intelligence.

Progress is not syncing

  1. Sign in with the same Apple Account on each device.
  2. In the Settings app, tap your name, then iCloud, and make sure iCloud is on for CS Revision.
  3. In the app, open Settings → Data & Sync and check that iCloud Sync is active.
  4. Connect both devices to the internet, open the app on each and allow a few minutes. Low iCloud storage or Low Power Mode can delay syncing.

Restore Full Access

  1. Make sure you are signed in to the App Store with the Apple Account that made the purchase.
  2. Tap the gear button on Home to open Settings, then tap Restore Purchases. It is also on the Full Access screen.

Full Access is a one-time purchase, not a subscription. For billing questions or refunds, use Apple’s Report a Problem.

Practice reminders

Open Settings → Practice Reminders to turn on a daily reminder and choose its time. The app asks for notification permission only when you turn it on.

Not getting reminders? If notifications are off for the app, use the button on that screen to open the Settings app and allow them.

Add the Due Review widget

  1. Touch and hold an empty area of your Home Screen.
  2. Tap Edit, then Add Widget.
  3. Search for CS Revision, choose Due Review and add it.
  4. Tap the widget at any time to jump straight into Due Review.

Export your progress

Open Settings → Data & Sync → Export Study Progress and choose where to save or send the file. It is a readable JSON summary of your progress, practice history and bookmarks. It does not include your typed answers, answer keys or purchase information.

Reset or delete your data

Settings → Data & Sync → Reset All Progress clears lessons read, practice history, answers, review dates and bookmarks on all your devices. Your study profile and Full Access stay.

To remove everything, delete the app, then delete its data from iCloud in the Settings app under your name → iCloud. Exported files are separate copies you delete yourself.

  2. Choose what seems wrong and add any details.

Frequently asked questions

Does the Question Coach send my questions anywhere?

No. It runs on your device using Apple Intelligence. Conversations are not saved and nothing you type is sent to us. See the Privacy Policy.

Can I use the app without iCloud?

Yes. Without iCloud your study data is saved on that device only and does not sync between your iPhone and iPad.

Does the app work offline?

Yes. Lessons and practice questions are built into the app. Syncing, purchases and restoring Full Access need an internet connection.

Is Full Access a subscription?

No. It is a single, one-time purchase. You can restore it on your other devices with the same Apple Account.

How do I get a refund?

Apple handles all payments, so refunds are requested from Apple at reportaproblem.apple.com. We cannot see or refund App Store payments ourselves.

Which devices are supported?

iPhone and iPad with iOS 26 or iPadOS 26 or later. The Question Coach also needs a device that supports Apple Intelligence.

I used version 1. Where is my account?

Version 2.0 is a fresh start with no accounts, so version 1 accounts, community features and progress are not carried over. If you would like your version 1 account data deleted, email gdoch9@gmail.com from the address you used for it.

Is this an official IB app?

No. CS Revision is an independent revision aid. It was developed independently from, and is not endorsed by, the International Baccalaureate (IB). Use it alongside your teacher’s guidance and the official course materials from your school.
