The Problem vs The Solution

The blind submission headache is over.

Preview without developer accounts

Marketers validate and finalize store listings independently. Hand over paste-ready copy to developers.

Previously:Drafting blindly in docs without device context

Live updates vs. binary releases

Instantly distinguish what changes go live on the fly versus what requires developers to compile a new build.

Previously:Zero visibility into app rebuild requirements

Realistic phone & tablet mockups

Preview in real time across phone and tablet screens. Catch awkward text cutoffs long before release day.

Frequently asked questions

Everything you need to know about Store Preview Studio, licensing, and offline usage.

Does Store Preview Studio ensure my app will pass App Store or Google Play review?

No, and no software tool on the market can. Store Preview Studio gives you realistic visual mockups and catches mechanical formatting mistakes (such as wrong icon dimensions, transparent alpha channels on iOS, or invalid screenshot aspect ratios). However, final app approval is determined entirely by the official Apple and Google review teams based on your compiled code, privacy policies, and store guidelines.

Does Store Preview Studio really work offline?

Yes. All mockup rendering, metadata drafting, character counting, and 4K exporting run directly inside your browser with zero tracking and zero server storage. An internet connection is only needed if you choose to import a public store listing from a URL.

Where can I find the exact character limits and submission rules for Apple & Google Play?

Official specs are scattered across Apple Developer and Google Play Console documentation. If you'd rather not dig through dozens of doc pages, we've summarized all exact rules, character limits, and asset dimensions into a single free reference sheet.

How do updates work after purchase?

You receive all maintenance patches and store spec adjustments for the current version for free via your download link. Major future editions with new platforms or hardware generations will be offered to existing customers at a steep upgrade discount.
