Overview
When it comes to health and habit-change apps, the right tool depends entirely on your specific goal. Ellie and SoloUno are two distinct apps designed for very different challenges. Ellie focuses on weight maintenance after or during GLP-1 medication (like Ozempic or Wegovy), while SoloUno targets body-focused repetitive behaviors (BFRBs) such as hair pulling, skin picking, and nail biting. This comparison will help you understand their features, pricing, and ideal use cases.
What is Ellie?
Ellie is a week-by-week companion app for people coming off or reducing GLP-1 medications. It helps you maintain weight loss by tracking your trend line, setting a personal "line you will not cross," and providing a structured After Plan that anticipates the biological phases of appetite return. Key features include a Food Noise SOS panic button, a protein and strength floor, and a bring-to-your-prescriber export. The app never suggests doses—it simply records your regimen and supports your decisions. Ellie is free to download on iPhone, with a subscription unlocking the full plan. An Android version is planned.
What is SoloUno?
SoloUno helps people take control over body-focused repetitive behaviors (BFRBs) such as hair pulling (trichotillomania), skin picking (dermatillomania), and nail biting. Inspired by Habit Reversal Training, CBT, and ACT, it works as a gamified self-help tool. You progress by achieving small daily wins: habit-free challenges and streaks, quick habit logging, trigger analysis, and urge-acceptance sessions. No shame—just steady progress. SoloUno offers a 2-week free trial and is available on mobile and desktop.
