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

- Tap Add to Home Screen
This gives you a home-screen icon that opens full-screen, without Safari's address bar.
Why Install the App?
- Faster access — one tap from your home screen or Start Menu, no typing a URL
- Works offline — calculators still load without a signal, since the math runs locally on your device
- Same site, same trust — it's the identical calculators from usafincalc.com, just packaged as an 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.
