Requirements

System requirements

Page Turner runs on iPhone and iPad with iOS or iPadOS 17.0 or later.

Note The app installs under the name iTurner. Use that name to find it on the Home Screen and in the device Settings app list — for example when you change a permission or check storage use.

In-app Settings is organised into four tabs: General (account, reading preferences), Assistant (AI features), Sync (iCloud backup and storage), and Dev (diagnostics). This page names the tab whenever a requirement is checked or changed there.

Storage

Importing stores a copy of each picked file inside the app; the original file is not moved or modified. Keep enough free space for:

• the copied score files — large PDFs, page images, and bulk imports add up;
• takes you record in Recording Studio.

To see what the app is using, open the Sync tab of Settings: the On this device row shows the total with a per-category breakdown, and Free up space now merges duplicate re-imported scores and removes orphaned files no score points to. It asks for confirmation first and does not touch your annotations.

Files kept in iCloud Drive or another Files provider may need to download before they can be imported. That download is controlled by iOS and the provider, not by Page Turner.

Network

Reading a stored score, turning pages, and annotating work without a connection. These features need one:

• Browsing and opening scores from the Catalog tab.
• Convert to Smart Score (PDF → editable notation runs on the conversion service).
• Assistant answers that use the cloud service. With Apple Intelligence (on-device) turned on in the Assistant tab, answers the on-device model can handle work without a connection.
• Ask our server when a page is too hard (Assistant tab): when a page can't be mapped on the device, that page is sent to the analysis service to place the tracking bands. Off, you place the bands yourself on those pages.
• iCloud Backup & Sync in the Sync tab of Settings.

Note Cloud page analysis is opt-in. The first PDF import shows a one-time consent sheet (Enable / Not now); the same switch stays available afterwards in the Assistant tab.

Feature requirements

See Permissions for what each system permission is used for and how to change a decision later.

Limit On devices where the system document camera is unavailable, Scan a score does not appear in the Add score menu at all — it is absent, not disabled.

Note Apple Intelligence (on-device) is free: it runs entirely on the device, with no account and no usage limits. On devices without Apple Intelligence support, the assistant uses the cloud service instead, which needs network access.

Page pedals

Page-turn pedals — AirTurn, PageFlip, Donner, and the like — pair with your iPad as a Bluetooth keyboard in the device Settings, under Bluetooth. Once paired, they turn pages in Page Turner with no extra setup and no in-app permission request. Pedal and face-gesture options live in the reader's Toolbox, not in the app Settings tabs.

Accounts

Two separate sign-ins matter, and they are easy to confuse:

• Apple Account (in-app) — Sign in with Apple, at the top of the General tab of Settings. Signing in unlocks PDF → MusicXML conversion beyond the anonymous free allowance and contributing scores to the public library.
• iCloud (device-level) — the account the device itself is signed in to. It backs iCloud Backup & Sync in the Sync tab and the iCloud Drive locations in the Files picker.

Important Signing in with Apple Account inside the app is separate from being signed in to iCloud on the device. A feature may depend on one, both, or neither.
