The first website edition
This edition includes seven calculator routes using one monthly engine, with fixed-minimum baselines, Snowball and Avalanche comparisons, monthly schedules, and a locally generated date-only share card.
Three launch guides cover starting a payoff plan, comparing methods, and exploring sustainable extra payments. Their worked examples are generated from the calculator engine.
The site also includes its calculation methodology, editorial policy, source notes, and privacy information. This note records the website build, not an App Store release or a claim that the domain is already deployed.
