Frequently asked questions
How do I restore my Formulae Pro purchase on another device?
Sign in with the same App Store or Google Play account you used to purchase. Open the app, go to Settings and tap "Restore purchases".
Which platforms is Formulae available on?
App Store (iOS), Google Play (Android), Microsoft Store (Windows), AppGallery (Huawei) and as desktop builds for macOS and Linux.
Can I download formulas to study offline?
Yes. Formulae Pro lets you export any formula sheet to PDF for printing or saving. Formulae Community does not include this feature.
What is the difference between Pro and Community?
Pro removes ads and adds tasks, PDF export and a ChatGPT-powered assistant. Community is free but ad-supported and lacks those extras.
