The 18-Minute Workout is built for anyone—any age, any fitness level—to train anywhere, in the shortest time required to live young. Designed by Shane Ellison and Lea-Ann Ellison—and led in part by their daughter Lily Ellison—this precision-engineered system targets hormone Balance, Output, and Sensitivity (BOS). In just 18 minutes, strategic aerobic and anaerobic intervals trigger hormesis—a powerful biological response that drives fat loss, supports muscle growth, and sharpens energy and focus without wasted time or guesswork. Paired with the Discipline Dashboard, the app tracks your adherence to the Core 3 disciplines of Living Young—workout, get sunshine, and quit sugar—turning proven habits into real accountability. The result: improved insulin sensitivity, faster recovery, controlled cravings, and a body that performs younger, longer.

Both are free to download. The 18 sells 2 in-app purchases, starting at $19.99 per month and SipFirst sells 2 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.9 for The 18 against 5.0 for SipFirst. That said, the two scores are not equally well evidenced: The 18 has 401 ratings behind it against 1, so its average is the more settled of the two.
