LaunchLedger

LaunchLedger is a web app (with optional mobile companion) for self-published authors who are tired of guessing what actually drives book sales. It pulls together your promotional calendar, ad spend, newsletter swaps, price changes, and platform metrics into one timeline so you can see what happened and what it likely caused. Instead of pretending it can perfectly attribute sales (it can’t), it focuses on practical correlation: before/after deltas, channel-by-channel trends, and repeatable “launch playbooks” you can reuse. You can log events manually or connect accounts where available, then generate a simple post-launch report: what cost money, what moved the needle, and what to stop doing. It’s not a magic growth button—just a clearer dashboard for decisions that authors already make under uncertainty.
