How the apps work

All Pancho Whampoa apps are offline calculators. There are no accounts, no logins, and no syncing. Everything runs on your device — just enter your numbers and get your answer.

Frequently asked questions

• Do I need an account? No. Open the app and start calculating.
• Does the app save my data? Some apps save your last-used settings locally on your device for convenience. Some apps allow you to manually store and recall your data. This data never leaves your phone.
• Does it work without internet? Yes, fully offline.
• I found a bug or a wrong calculation. Please email us — this is exactly the kind of thing we want to know about.
• Can I request a feature? Absolutely. We read every email.
