What Leanos is
Leanos is an iPhone app with an AI coach and the trackers built in. You log meals by photo or by typing what you ate, your steps sync from Apple Health, and your lifts, weight and progress photos sit in the same app. The coach answers from all of it, so when you ask how your week went, the answer comes from your own meals, training and weight.
It's built for people coming off a GLP-1 who want to keep the weight off, whether they're planning to stop, stepping down, or already off. It works for anyone holding or losing weight.
Leanos gives no advice on starting, stopping, tapering or going back on a medication. Those decisions belong to you and your prescriber.
Who makes it
Leanos is made by LeanOS Inc., an Ontario corporation federally incorporated in Canada. The app has been on the App Store since June 2026.
Who writes the guides
The guides on this site are published under the byline YK Carap Cirtap, the pen name Leanos uses for its health writing. The editorial standards set out how every page is sourced, and the coming-off dataset explains how we read and coded 4,014 posts from people coming off a GLP-1.
