Choose an exam area and study without creating an account. Pro access covers the areas included in the flagship app, but does not unlock the website or separate exam apps. Monthly and annual subscriptions and a one-time lifetime option are available. Only eligible monthly subscribers receive a three-day trial; annual and lifetime have no trial. Apple shows current local pricing before you confirm.

Study history, plans and bookmarks are stored on your device and do not sync with the website. Restore Purchases restores eligible Pro access, not deleted study history. Avoid deleting the app if you need to preserve local progress. If access is missing, use the original Apple Account, check your network connection and retry Restore Purchases in Settings.

Usage analytics are optional and off by default. Use Share usage analytics in the app’s Settings to change your choice. Study reminders are scheduled locally after you grant notification permission; turn them off in the app or iOS Settings. These settings are separate from web cookie preferences.

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. Restoring an eligible purchase is free and requires Apple verification; retry with a network connection if access is not restored.

Native app purchase options vary by app. MLO Exam Prep offers monthly, annual and lifetime Pro access. Only eligible new monthly subscribers receive a 3-day free trial; annual and lifetime plans have no trial. Confirm current regional prices and terms on the in-app purchase screen. Web plans are separate products.

No. Web, iOS, and Android are separate products today. A web purchase unlocks the browser platform at voltexam.com. An iOS purchase is tied to your Apple ID and unlocks that native iOS app. An Android purchase is tied to your Google Play account and unlocks that Android app. We do not currently have cross-platform account linking.

Most VoltExam apps include between 500 and 1,500 practice questions depending on the certification, for a total of 35,000+ questions across all 43 apps. Each app also includes detailed explanations for every answer so you understand the reasoning, not just the right letter.

Yes. All practice questions, study tools, and built-in calculators work completely offline. You can study on a job site, on the road, or anywhere without cell service. The only feature that requires internet is restoring purchases on a new device.

Every trade is available on iPhone and the web at voltexam.com, and a growing set of apps is also on Android (Google Play). Offline access is built into the native apps.

Yes. We review and update our question banks when exam standards or codes change — for example, when a new edition of the NEC is adopted or when the NREMT updates its test plan. Updates are delivered automatically through the App Store at no extra charge.

For Apple in-app subscriptions, go to iPhone Settings → your name → Subscriptions and select the app. Cancel before the trial or subscription renews. Lifetime purchases do not renew. Manage web subscriptions separately at voltexam.com/account under Billing.

Yes, within the same platform. Web access follows your VoltExam account email across browsers. iOS purchases follow your Apple ID across iPhone and iPad. Android purchases follow your Google Play account. Purchases do not currently transfer between web, iOS, and Android.

Free accounts on voltexam.com get 25 practice questions per trade — no credit card required. A paid plan ($9.99/month, $29.99/year, or $59.99 lifetime) unlocks unlimited questions across all 43 trades and saves your full study history.

If a payment fails, we'll email you right away and keep your access active for a short grace period while you update your card. Go to voltexam.com/account and click Manage Billing to update your payment method. If the card isn't updated in time, access is paused until the next successful charge — no data is lost.

Sign in at voltexam.com and go to Account. Your recent sessions, best score per trade, and overall progress are all shown there. Study history is tied to your account email, so it follows you across any browser or device.

For Apple App Store purchases, request a refund at reportaproblem.apple.com; Apple determines eligibility under its policies and applicable consumer law. The following applies to web purchases only: all sales are final and we do not offer refunds. That's exactly why the monthly plan includes a 3-day free trial before billing starts. Cancel anytime before day 4 from your Account page and you won't be billed. If a technical problem ever blocks your access, email us at arun@voltexam.com and we'll fix it right away.

Use the Contact Support button below — it opens an email directly to our team. We typically respond within 24 hours on business days. Please include which app you're using, your device model, and a description of the issue.
