Book Tracker is available on the entire Apple ecosystem:
- 📱 iPhone (iOS)
- 🖥️ iPad (iPadOS)
- 💻 Mac (macOS)
- ⌚️ Apple Watch (watchOS, paired with the iPhone)
Your library is the same across all of them and stays in sync through iCloud, no account required.
How purchases work
Book Tracker is sold as a one-time purchase per platform, not a subscription:
- One purchase covers the iPhone + iPad + Apple Watch apps (they all live in the same iOS/iPadOS app).
- A separate purchase is needed for the Mac app.
Both are available on the App Store / Mac App Store. Once you’ve purchased Pro, all future updates on that platform are free, as they have been since 2019.

A note on Apple Watch
The Apple Watch app is included with the iOS purchase, there’s nothing extra to buy. It mirrors a subset of your library from the paired iPhone and lets you:
- See what you’re currently reading
- Start, pause, and stop a Reading Timer from the wrist
- Log reading progress
The Apple Watch app needs the iPhone app to work, it’s not a standalone app.
