Why Appsium

Most apps are not lost on quality. They are lost on a store page nobody can find, written in one language, with screenshots that don't sell and a rejection waiting in App Review. Appsium fixes the page, so the product gets its chance.

From a blank brief to a
ready-to-ship listing.

App brief

Describe your app once

Connect App Store Connect or just paste an App Store link. A short brief captures purpose, audience, features, tone and target countries. Or let AI draft it from your current listing.

Competitors & keywords

Find the words people search

Appsium discovers your real competitors from App Store results, scores keyword coverage across title, subtitle and keyword field, and shows monthly search volume and 12-month trends for every keyword. Connect Apple Ads to add Apple's own popularity scores.

Metadata editor

Write it in every language

Generate title, subtitle, keywords, promo text and description per locale, always inside Apple's character and byte limits. Then preview exactly how it will look on the store.

Screenshot studio

Turn your app screens into store-ready visuals

Generate a campaign with AI or start from a template, for iPhone, iPad and Apple Watch. Localize the finished set into every language and upload it straight to App Store Connect.

Pre-Review Check

Catch potential review issues before Apple does

Pre-Review Check walks through the guidelines that reject most apps: Sign in with Apple, account deletion, paywalls, privacy, store text and screenshots.

One workspace.
Fewer launch headaches.

Search simulator

See what people find when they search for your app.

Run a search as if you were on the App Store in Germany, Japan or Brazil and see exactly where your app lands next to competitors.

Questions,
answered.

Still curious? Write to support@appsium.io.

Do I need to connect App Store Connect?

No. You can add any app by name or App Store link and prepare all of your store text without sharing a key. Connect App Store Connect when you want to pull live metadata and screenshots or push changes back.

How is my App Store Connect key protected?

Keys are stored with envelope encryption using Google Cloud KMS and are only decrypted on our servers when you ask Appsium to talk to Apple on your behalf. You can remove a key at any time.

What is a credit, and what happens when I run out?

Credits are a single balance for every AI action, from rewriting a subtitle (2 credits) to a full ASO analysis (18 credits). Monthly credits refresh each billing month; credit packs and your free sign-up credits never expire. If an action fails, its credits are refunded automatically. When you run out, everything you created stays in your workspace.

I don't have a website. Where do my privacy policy and support pages go?

Appsium can host them for you. Answer a few questions about the data your app collects, and App pages builds a landing page, a privacy policy, terms of use and a support page on appsium.page, with URLs you can paste straight into App Store Connect. They're included on every plan, including Free.

Can I cancel or get a refund?

Yes. Cancel from your account and your plan stays active until the end of the period you paid for. Within 14 days of a purchase or renewal you get a full refund if you have not used its credits, or the unused share if you have. Payments and refunds are handled by Paddle, our Merchant of Record. See the Refund Policy.

store page it deserves.
