Online Prescence and Trading
Cosmic Sway Method® was established online following registration of the domain cosmicswaymethod.com on 28 December 2021. Public trading commenced in January 2022, with consultations, digital tools and related services offered directly through the official website prior to wider retail publication of the first edition.
Publications
The first edition of The Cosmic Sway Method was written in 2021 and launched via the official website in February 2022. In September 2022, the e-book edition was published through Amazon Kindle Direct Publishing, extending retail distribution.
A professionally published second edition, The Cosmic Sway Method: Choose the Sex of Your Next Baby, was released on 06 November 2024 by Michael Terence Publishing under ISBN 9781800948938 and is available through major retailers including Waterstones and Amazon.
App and Technology
Development of the Cosmic Sway App began in February 2022 alongside expansion of the method’s digital framework. Following over a year of internal development, the application launched publicly in 2023 across iOS and Android platforms.
The app was originally released under its prior title and was renamed to Cycle Aligned Fertility TTC following a platform update in February 2026. The application is built using proprietary software developed internally rather than relying on third-party astrology or calendar platforms. This enables the application of internally defined lunar transition standards and fertility timing calculations within a consistent system.
While the full multi-layer polarity analysis remains part of consultation-based services, the app provides structured lunar transition timings and fertility tracking tools aligned with the wider Cosmic Sway Method® framework.
