How to Install

Install Certaminis on your phone or computer for one-tap access — the official closed-beta install path, no app store required.

Closed beta

Certaminis is not on the Google Play Store or Apple App Store yet. During closed beta, you install it directly from the web — the same way many products ship before a public store listing. Web install is intentional: it lets beta testers get the real app experience now, without waiting for store review.

One-tap launch

Open Certaminis from your home screen or Dock — no typing the URL.

App-like window

Runs full screen without browser tabs and chrome clutter.

Same secure app

Identical sign-in, registrations, and payments as the website.

Your browser has not offered one-tap install yet. Follow the written steps below for your device — or visit this page again in Chrome or Edge after browsing for a moment.

Common questions

Why isn't Certaminis in the app store?

Closed beta builds ship over the web first. Store listings come later once we're ready for a public release.

Do I need to install again after creating an account?

No. The installed app and your account are separate — sign in once inside the app and you stay signed in on that device.

What if my browser never shows an install button?

Follow the written steps for your platform below. iOS requires Safari; Android and desktop work best in Chrome or Edge.

Can I remove How to Install from the menu?

Yes. After you've installed and signed up, open Settings and turn off Show How to Install in navigation.

All set? Hide this from the menu

Once you've installed Certaminis and created an account, you don't need How to Install in the top navigation anymore. After you sign up, open Settings and turn off Show How to Install in navigation. You can always return to this page at certaminis.com/install.
