Your backlog isn't
going to track itself.

Backlog Zero is free for macOS 12+ and Windows 10+, requires no account, and keeps your data exactly where it belongs — on your machine.

Pay what you want — including nothing. Downloads are handled via itch.io. Available for macOS 12 or later and Windows 10 or later. Mac users will need to approve the app on first launch — see the FAQ for instructions.

All of it. No tiers, no asterisks.
