There are two ways in:
- While reading, tap Reader settings (the gear at the top). Changes show straight away behind the sheet; More reading settings opens the full list.
- From the library, open Settings and choose Reading & Appearance. A preview at the top shows how text will look.
Free for everyone
- The Automatic, Light and Dark themes. Automatic follows your device.
- Text size for the reading text, separate from the size of the rest of the app, which follows iOS text size.
- The System font and OpenDyslexic, a dyslexia-friendly font.
- Focus guides and Hide controls while reading.
- The accessibility settings it supports: larger text, increased contrast and Reduce Motion. Accessibility is never part of Pro.
With Pro
- More themes (True Black, Sepia, Paper, Dusk and Forest) and Custom with your own Background and Text colours.
- More fonts, such as New York and Rounded.
- Focus letter on or off, and its Focus letter color.
- Presets: tap Save Current Settings as Preset… and give it a name, such as Night or Study. Switch between presets in one tap; swipe one away to delete it.
On the free plan, Pro settings show a lock. Tapping one opens the Pro offer and leaves your current settings exactly as they were.
Your choices are kept
If you set something up during the 7-day Pro trial and the trial ends, the reader goes back to the free look, but nothing you chose is deleted. Buy Pro later and it all comes back; Settings → Plan says how many of your saved customizations Pro would restore.
