About these ASO tools
What are ASO tools?
ASO (App Store Optimization) tools help app developers improve how their app is found in the App Store and Google Play and how well its listing converts. That covers keyword research (finding the terms people search), auditing a listing for a score and fixes, writing metadata like promotional text, sizing icons and screenshots to each store's exact requirements, generating badges and QR codes, and analyzing keyword density. Appure gives you all of these, free.
Is there a free ASO keyword research tool here?
Yes. The ASO keyword research tool takes a seed term and returns real App Store and Google Play suggestions from each store's own autocomplete, each scored for traffic and difficulty so you can find low-competition keywords worth targeting. It's free with no login and no paid API — the one thing it can't show is the exact monthly search count, which the stores keep private.
Are these ASO tools free?
Yes, every tool here is completely free with no sign-up. The keyword research and ASO audit tools read live, public App Store and Google Play data on our server; the rest run entirely in your browser, so there's nothing to install and nothing to pay for.
Do these tools upload my app's assets or data?
No. Everything runs client-side in your own browser — icons, screenshots, and text you enter never leave your device. That means the tools work on unreleased assets without any privacy exposure, and some keep working offline once loaded.
Do these tools work for both the App Store and Google Play?
Yes. The tools cover iOS and Android where each applies — for example screenshot and icon sizing, badges, and QR codes exist for both stores, while store-specific fields like App Store promotional text or the Google Play feature graphic target one store.
