Free Tools for App Store Optimization
Optimize your app store listings with our free ASO toolkit. Every tool is designed to help developers and marketers ship better-performing metadata without guesswork.
Why Free ASO Tools Matter
App Store Optimization is the foundation of organic growth for any mobile app. Whether you're publishing to the Apple App Store or Google Play, every character in your title, subtitle, and description counts toward discoverability and conversion. Getting metadata right from the start saves time, prevents rejection, and maximizes your ranking potential.
Our free tools help you validate your metadata before you submit it. The character counter ensures you stay within the strict limits imposed by both platforms, while the screenshot size calculator gives you the exact pixel dimensions required for every device type. These are the same checks our AI metadata generation engine runs automatically, now available as standalone utilities for anyone to use at no cost.
Each tool is built for speed. Paste your text, pick your field type, and see results instantly. No sign-up, no login, no limits. When you're ready to take your ASO to the next level, explore the full AppDrift platform for AI-powered metadata creation, translation into 40+ languages, and one-click store publishing.
