Frequently asked questions

What is App Store Optimization (ASO)?

ASO is the process of improving your mobile app's visibility in the App Store and Google Play search results. It includes optimizing your title, keywords, description, screenshots, and other metadata to rank higher and attract more organic downloads.

What does ASOZen do?

ASOZen is an ASO analytics platform. It analyzes any app on the App Store or Google Play and gives you a detailed score, keyword analysis, competitor insights, and prioritized recommendations to improve your store listing.

What is the Creative Audit?

The Creative Audit reviews your screenshots against ASO creative best practices. It checks the first-screen hook, screenshot sequence, caption clarity, feature-to-benefit framing, and whether an app preview video is worth testing for that app type. You can also upload candidate drafts, drag to set the order, audit them against the same rubric, and compare side-by-side with the published set before shipping. Uploaded drafts stay on your device, never on our servers.

Is ASOZen free to use?

Yes. Free accounts include 3 full app audits per month, 10 keyword checks per month, up to 1 saved app, 1 AI generation total, full ASO scoring with prioritized fixes, keyword rank checks, competitor comparison, and Creative Audit preview only. Starter is for regular basic usage without free-plan friction: 10 analyses per day, 50 keyword analyses per month, up to 3 saved apps, daily automated tracking, 14-day recent changes, a basic weekly digest, competitor comparison, and 10 shared AI credits each month. Advanced workflow tools remain on Pro. Pro unlocks score history, keyword trend history, weekly tracking digests, recent changes, smart recommendations, bulk keyword scoring, the What-If Optimizer, Release Planner, Market Opportunities, Brand Safety reporting, CSV exports, and 50 shared AI credits each month for AI Metadata Writer and Creative Audit.

Do I need to connect my developer account?

No. ASOZen analyzes publicly available store listing data. You do not need to connect your Apple Developer account or Google Play Console. Just search for any app by name, URL, or bundle ID.

Why does ASOZen offer Google sign-in?

ASOZen uses Google sign-in as a fast, secure way to create your account. We only access your name and email address to identify your account. We do not access your Google Play console, app data, or any other Google services.

Which platforms are supported?

ASOZen supports both the Apple App Store (iOS) and Google Play Store (Android). You can analyze, compare, and track apps on either platform from a single dashboard.
