Does Solve f(x) need an internet connection?

No. Every calculation runs on your device, so it works in airplane mode, in an exam room, or anywhere without signal.

What does Solve f(x) Pro unlock?

Degree 4 and higher, complex roots, multiplicity detection, extended precision at 8 or 12 decimal places, and solve history. It is a single one-time purchase, not a subscription.

How do I restore my purchase on a new device?

Open Settings inside the app and tap Restore Purchases.
