Overview
Ellie is a mobile application created for individuals who have taken GLP-1 medications such as Ozempic, Wegovy, Zepbound, or Mounjaro and are now looking to maintain their weight loss after the medication has been reduced, tapered, or discontinued. The app, built by Metellus Productions, offers a structured, week-by-week plan designed to help users navigate the physiological and psychological transitions that occur when these medications are no longer part of their routine. Based on the premise that the appetite returns on a predictable schedule, Ellie aims to give users a roadmap for what comes next, focusing on holding the line against weight regain. The product is currently available for iPhone on the App Store, with an Android version planned for the future. Ellie positions itself as an educational companion rather than medical advice, and it never suggests dosing or intervals. Instead, it brings the user's chosen regimen into a supportive framework that includes trend tracking, protein and strength targets, and tools to manage food noise.
Services & Expertise
Ellie offers a range of capabilities that directly address the challenges of transitioning off GLP-1 drugs. Its core services include:
-
The After Plan: A personalized, week-by-week timeline that starts from the last dose or current taper stage. The plan details when water-weight jumps typically occur, when food noise peaks, and which weeks pose the highest risk for regain. By mapping out these milestones, Ellie ensures users are prepared and know what actions to take during each phase.
-
Food Noise SOS: An emergency feature designed for moments when cravings or obsessive thoughts about food become intense. The SOS tool walks users through a 10-minute protocol and provides a chart that tracks the decline of food noise over time. This feature is intended to give users a concrete way to manage their mental and emotional response without relying on willpower alone.
-
Trend Line Tracking: Users define a threshold weight they are not willing to exceed. Ellie monitors the 7-day moving average rather than isolated daily weigh-ins, allowing it to detect drift at 4 pounds instead of 20. This early warning system helps users take corrective action before small gains become large ones.
-
Protein and Strength Floor: To combat muscle loss during maintenance, Ellie sets daily protein targets and recommends 20-minute strength training sessions that can be done at home. The emphasis is on maintaining lean mass, with no requirement for excessive cardio, and the program is designed to be sustainable for people with busy schedules.
-
Medication Modeling: Ellie adapts its recommendations based on the exact way each user is taking their medication, whether it is a standard weekly injection, a stretched dose, a stepped-down taper, or complete cessation. The app incorporates the user's regimen into its calculations but explicitly avoids suggesting any changes to dose or frequency.
-
Bring-to-Prescriber Export: This feature generates a clean, one-page summary containing the user's real medication regimen, weight trend, and plan in progress. This document is designed to be shared with a clinician, facilitating more productive conversations about the next steps in the patient's treatment journey.
-
Free Educational Tools and Guides: The website also hosts a suite of free calculators, including a washout calculator, microdosing chart, taper schedule visualizer, maintenance calorie calculator, and protein calculator. Additionally, there are 26 evidence-based guides covering topics such as what happens when you stop Ozempic, how to wean off GLP-1s, whether lifelong use is necessary, and how to manage side effects like nausea, hair loss, and fatigue.
How They Work
Ellie operates as a mobile companion that begins with a single goal: help users hold a predetermined weight line. The onboarding process starts with setting that boundary number, the weight that the user is determined not to cross. From there, the app asks users to log their weight each morning. Over time, Ellie builds a 7-day trend line, which is far less sensitive to daily fluctuations than individual weigh-ins. Based on the trend, the app provides feedback and adjusts the user's weekly plan. For example, if the trend shows a 4-pound drift upward, Ellie signals a "tighten week," where the user may be asked to increase protein intake, add strength sessions, or use the Food Noise SOS more frequently. The app also incorporates the user's specific medication schedule, whether they are still taking a weekly dose, stretching it out, or have stopped entirely. It uses published research and real-world clinical data to predict when appetite surges and water-weight swings are most likely. Users can expect to receive a week-by-week plan that evolves as they progress. The companion also includes a "Bring to Prescriber" export, which allows users to walk into appointments with a concise summary of their status, making it easier to discuss the right next steps with a doctor. The app is designed to be non-punitive; it does not shame users for missed days, but simply pauses and resumes when needed.
Ideal Client Profile
Ellie is designed for a specific population, and the following scenarios illustrate who could benefit:
-
The Recent Stopper: Someone who has taken Ozempic for over a year and decided to stop due to side effects, cost, or personal preference. They want to maintain the weight loss they achieved but are concerned about the well-documented 66% regain rate. Ellie provides the structure and early detection tools to help them stay on track.
-
The Tapering Patient: A Wegovy user who is working with their prescriber to step down their dose gradually. They are looking for a companion that understands the taper process and can adapt recommendations week by week as the medication level changes.
-
The Stretched Doser: An individual who, with medical approval, stretches their Zepbound injections to save money or manage supply. They need guidance on how to maintain good habits during the off-weeks, especially when food noise begins to creep back.
-
The Post-Mounjaro Maintainer: A person who has been off Mounjaro for several months and is doing well, but wants to ensure they keep their gains. Ellie's continuous trend tracking and protein floor can help them stay vigilant against slow, creeping weight gain.
-
The Evidence Seeker: A user who does not want to rely on hearsay or online forums. They value a tool that cites clinical studies like STEP-1 extension and SURMOUNT-4, and they want a systematic, research-backed approach to their maintenance journey.
Pricing & Engagement Models
Ellie is available as a free download from the Apple App Store. Once installed, users can begin logging their weight and accessing basic features without cost. The full plan, including the week-by-week guidance, Food Noise SOS, and all premium tools, requires a subscription. The website does not list a specific monthly or annual price, instead directing visitors to the App Store for current pricing details. The free tier also includes a handful of tools and guides that require no signup, allowing prospective users to try the product's approach before committing. The subscription model is typical for health and wellness apps that provide ongoing, personalized guidance. Given the app's focus on long-term maintenance, it is likely to be structured as a recurring monthly or yearly plan, though the exact terms are not disclosed on the landing page.
Why Consider Them
Ellie stands out in a crowded health app market because it addresses a very specific, underserved need: life after GLP-1 therapy. According to the site, there are zero published protocols for coming down from these medications, and most prescribers admit there is little guidance to offer. Ellie fills that void with a structured plan based on extension studies and clinic data. Its strength is not just in tracking weight, but in anticipating the psychological and biological changes that come with stopping or reducing the drug. The app's calm, non-judgmental approach is also a differentiator. Instead of turning health into a game that can be lost, Ellie acts as a steady companion, helping users maintain their results through architecture rather than willpower. The ability to export a prescriber-ready summary sets it apart from other trackers, aligning with the medical community's desire for data-driven conversations. While the app is currently iOS-only, its free tools offer a taste of the methodology, and for the target audience, the potential to avoid significant weight regain makes the subscription a compelling investment.
