📱 Android

Direct APK download — install it straight on your phone, no Play Store account needed.

⬇ Download for Android (.apk)

💡 First install only: Android will ask you to allow installs from this source. Go to Settings → Apps → Install unknown apps, allow it for your browser, then open the downloaded file. This is a standard Android prompt for any app installed outside the Play Store — it doesn't mean anything is wrong.

🖥️ Windows

Installable MSIX package for Windows 10/11 — runs as a proper desktop app with its own Start Menu entry.

⬇ Download for Windows (.msix)

💡 After downloading, double-click the file to install. If Windows SmartScreen shows a warning because the app isn't yet signed through the Microsoft Store, click More info → Run anyway.

🍎 iOS / iPhone

A direct download isn't available yet. In the meantime, you can add USAFinCalc to your home screen for a full app-like experience:

This gives you a home-screen icon that opens full-screen, without Safari's address bar.

Why Install the App?

Frequently Asked Questions

Is the USAFinCalc app free?

Yes. No sign-up, no in-app purchases — it's the same free calculators from usafincalc.com, packaged as an installable app.

Is the Android app safe to install outside the Play Store?

Yes. It's a direct APK download of the same app we submit to app stores. Android shows an "unknown sources" warning the first time you install any app this way — that's a standard OS prompt, not a sign of a problem.

Is there an iOS app?

Not yet available for direct download. Use "Add to Home Screen" in Safari in the meantime — see the iOS section above.
