In short: two options. “Add to Home Screen” uses the browser — no app store. The APK is an Android install file when you want a separate system app icon.

Which to choose

Add to Home Screen — the site opens like an app: its own icon and a fuller screen. Best for most people. No store download.
Serpmonn for Android (.apk) — an install file. Useful if the browser doesn’t offer install, or you want a classic Android app icon.
Serpmonn Messenger — a separate Android app (pre-alpha). There is no web chat yet: the menu item opens a page where you download the Messenger APK.

Add to Home Screen

Open serpmonn.ru in your phone browser, then follow your OS.

Android (Chrome): browser menu (⋮) → “Install app” / “Add to Home screen” → confirm. Or in the Serpmonn menu: Apps → “Add to Home Screen”.
iPhone / iPad (Safari): Share → “Add to Home Screen” → Add.
Then open the Serpmonn icon from your Home Screen — it launches without the full browser chrome.

If you don’t see Install, update the browser or try Chrome / Safari. On some devices the option appears after visiting the site again.

Download for Android (.apk)

Find it under Apps → Mobile apps → “Serpmonn for Android (.apk)”.

Download the file to your phone.
Open the download. If Android asks to allow installs from that source, allow it for the Files app or browser.
Install and open Serpmonn from the Home Screen.

This APK is not from Google Play, so Android may show a warning — expected for sideloading. Only download from serpmonn.ru.

About Messenger

“Serpmonn Messenger” opens the app page. Messenger currently works only as a native Android app — download the APK from that page and install it on your phone. You cannot chat in the browser yet; a web client is not available. This is not the same as “Serpmonn for Android” (site shortcut): Messenger has its own install file.

FAQ

Home Screen vs APK?

Home Screen is a browser-installed shortcut to the site. APK is an Android package. Both open Serpmonn; pick APK if browser install isn’t available.

Do I need Google Play or the App Store?

No. The browser or the site APK is enough.

Is it safe?

Install only from serpmonn.ru. Don’t install “Serpmonn” from random sites or messages.

Can I install both?

Yes, but one method is usually enough so you don’t end up with two icons.

Summary: Try “Add to Home Screen” first. If that fails, download “Serpmonn for Android”. Messenger is separate: Android APK only from its page — no web version yet.
