Frequently Asked Questions
Is Calculator Hub really free?
Yes! The core app with dozens of calculators is completely free to download and use — no sign-up required. PRO unlocks AI, scenario saving, and screenshot sharing for $3.99/month or $24.99/year.
Does it work without an internet connection?
100%. Every calculator runs entirely on your device. No data is sent anywhere and no internet is needed. It works on planes, in basements, wherever you are.
Is my data private and secure?
Your calculations, scenarios, and inputs never leave your device. We don't collect or sell personal data. There are no accounts to create and nothing is synced to a cloud without your consent.
Are there ads in the app?
Zero ads. Not on the free tier, not on PRO. We believe a calculator should be a tool, not a billboard. The app is funded entirely by PRO subscriptions.
Which platforms are supported?
Calculator Hub is available on iOS (iPhone & iPad) and Android. Download it from the App Store or Google Play Store — search "Calculator Hub" or use the buttons on this page.
