Open it in the browser first
If the product only works after a mystery sideload, that is not an app advantage. That is a risk.
App as in you will actually open it

An app is a habit. It should be easy to open and hard to misunderstand.

Who this setup is for
App-store shoppers want an icon, a badge, a rating, and a deposit button. That distribution channel trains people to trust a listing. OpenFidex is a web application you can install to the home screen. The icon is convenient. The listing is not the custodian.
What makes it an app instead of a brochure is the loop: you return, you see markets, you maybe sign. If you wanted a game with candles, there are plenty. This one keeps the adult sentences.
A short onboarding, then you stay in control
Install as PWA if you like icons
Home screen is fine. Read the origin. Phishing loves icons too.
Use the same account everywhere
Phone and desktop should not become two different custody stories.
Interface details that matter for this audience
Designed as software people reopen
Not a landing page that dies after the first scroll.
Mobile dock thinking
Thumbs exist. The product has to respect them without hiding the signature.
No rating-theater as proof
Stars are not an audit of the wallet model.
Sibling pages for form factors
Mobile, desktop, browser, PWA each have their own URL because the jobs differ slightly.
Questions this page actually answers
Is there an iOS / Android store build?
The supported path is web and installable PWA. Do not download a random “OpenFidex” binary from a third-party store listing you cannot verify.
Does the app work offline?
You may see a shell. You cannot honestly trade a live venue offline. Anyone who says otherwise is selling a screenshot.
Why not a native app?
A browser origin is easier to reason about than a privileged binary when the asset is a signing key.
Is this the same as the web-based page?
Web-based is the architecture. App is the habit and the icon. Different landing jobs.
Does OpenFidex hold my funds or place trades for me?
No. OpenFidex is a non-custodial software interface. A wallet is created in your browser, you keep the keys, and you cryptographically sign every order before it reaches a third-party venue such as Hyperliquid. The software does not take custody of assets and does not submit transactions unless you sign them.
