Book Tracker is sold as two separate apps: one for iPhone/iPad and one for Mac.

Why two purchases?

• Each app is developed and maintained independently, optimized for its platform.
• By keeping them separate, you pay only once per platform with a lifetime purchase.
• There are no subscriptions, no hidden costs, and no forced upgrades.

How Book Tracker differs from other apps

Many popular book apps use a different model:

• They often require an account, which means your reading data is stored on their servers.
• They may show ads or sell aggregated user data.
• They usually work with recurring subscriptions, so you pay every month or year to keep using them.

Book Tracker is different:

• Privacy-first: your data never leaves your devices or your private iCloud.
• No ads, no tracking, no selling of user data.
• One-time purchase per platform, with unlimited access.
• Free updates since 2019, including all major features released so far.
