How to Use the Roast My Screen Figma Plugin to Improve Your App UX

Most UX issues are caught too late. A paywall that confuses users, an onboarding flow with one step too many, a CTA that’s not compelling. By the time analytics surface the problem, the damage to retention and conversion is already done.

Roast My Screen changes that. Our AI-augmented Figma to Purchasely plugin reviews your UI screens directly inside your design environment, before a single line of code is written.

This guide walks through exactly how to use it, what types of screens it works best on, and how to act on the feedback it generates.

What Screens Can You Review?

Roast My Screen works across all major screen types in a mobile app.

Onboarding flows: Identify steps that add friction before first value, flag unclear value propositions, and surface unnecessary permission requests.

Paywalls: The highest-leverage screens in any subscription app. The plugin detects weak CTAs, missing social proof, confusing pricing layouts, and poor benefit communication.

Feature screens: Reveal cognitive overload and inconsistent UI patterns

General UI screens: Can be audited for visual hierarchy issues, navigation clarity, and interaction design gaps.

Step-by-Step: How to Use the Plugin

Step 1: Install the plugin. Search for "Roast My Screen" in the Figma Community and install it directly into your Figma workspace.

Step 2: Open the screen you want to review. Select the frame or component you want to optimize. For best results, review one screen at a time rather than full flows.

Step 3: Run the plugin. Launch Roast My Screen from your plugin menu. The AI will analyze the selected frame and generate a structured feedback within seconds.

Step 4 : Fix them instantly. Click "Fix them" on any suggestion and watch the plugin auto-fix it directly in your Figma file, no manual edits needed.

Step 5: Iterate directly in Figma. Address each flagged issue in your design file before moving to handoff or development.

How AI Detects UX Problems

Roast My Screen is powered by an AI trained on UX principles, conversion design patterns, and mobile interface standards. It evaluates screens against established criteria and data points rather than subjective preference, which means the feedback is consistent and grounded in what actually affects user behavior.

This is especially valuable for paywall and onboarding screens, where even small friction points have measurable impact on conversion rates. To go further, we recommend you read our guide on the 10 Most Common UX Mistakes in Mobile Apps in 2026.

For Purchasely Users: From Figma to Live Screen

If you use Purchasely to manage your paywalls and create personalized in app interactions, Roast My Screen fits directly into your workflow. Once you have iterated on a screen in Figma and addressed the AI recommendations, you can transfer the optimized design directly into your Purchasely space, where elements are automatically translated into console components, without any involvement from engineering.

Ship Screens That Work

The cost of a bad UX decision compounds over time. Every user who drops off a broken onboarding flow or a confusing paywall is a conversion you will not recover. Roast My Screen puts a quality gate at the design stage, where fixes are fast and free.
