Frequently Asked Questions
Open the app on your new device, go to Settings (or the unlock/purchase screen), and tap "Restore Purchases." Make sure you're signed in with the same Apple ID you used for the original purchase. The restore is instant and free — you won't be charged again.
VoltExam is a one-time purchase of $17.99. You pay once and keep access forever — there are no monthly fees, no renewal charges, and no expiration date. All future updates to the app you purchased are also included at no extra cost.
Most VoltExam apps include between 500 and 1,500 practice questions depending on the certification, for a total of 19,000+ questions across all 19 apps. Each app also includes detailed explanations for every answer so you understand the reasoning, not just the right letter.

VoltExam apps are one-time purchases, not subscriptions — so there is nothing to cancel. If you accidentally purchased a subscription through a different app or service, manage it in iPhone Settings → your name → Subscriptions.
