Every new user gets 3 hours of full AI coaching free — lifetime, with no time limit on when you use it. If you want more, there are three subscription tiers: Pro (US$9.99 / NT$320 per month, 20 hours of practice), Pro Max (US$14.99 / NT$490 per month, up to 60 hours), or Pro Max Annual (US$89.99 / NT$2,990 per year, up to 60 hours per month — the best value). All auto-renew, cancel anytime, and are billed via the Apple App Store — the same payment method you already use for other apps.

Yes. No credit card up front, no auto-conversion to paid. You get 3 hours of full coaching with every feature: voice analysis, bilingual feedback, alternative phrasings, the whole thing. Use it across as many sessions as you like. When the 3 hours run out, you choose whether to upgrade.

Right now it's focused on English-language interview practice. That's the bottleneck most of our target users face. The app UI itself is available in English and 繁體中文 (Traditional Chinese). Practice answers can be given in either Chinese or English; coaching feedback is bilingual.

Your audio recordings are never uploaded to our servers. Speech-to-text runs through Apple's Speech framework — on-device where available, though Apple's servers may assist for some languages and devices. Only the text transcript and speaking metrics are sent to our backend for AI coaching. Full details in our Privacy Policy.

Yes, anytime. Settings → Delete all my data removes everything stored on your iPhone. To delete your backend data too, email us your device ID — it's included in the file from Settings → Export my data — and we'll remove it.

You can browse questions and review past attempts offline. Recording and AI coaching require an internet connection. Coaching responses come from our backend in real time.

Not yet. We're iOS-only at launch. The reasons: Apple IAP simplifies payments, iOS device consistency lets us ship faster, and our target users skew iPhone. We'll re-evaluate after we have real iOS traction.

Yes. Every drill returns a score from 0 to 100, plus an accuracy and fluency breakdown for refinement attempts. The score is one signal among many: the inline annotations, alternative phrasings, and coaching summary are usually more useful than the number.

Yes. When you set up your profile, you can specify a target role and target company. The app will use that to personalize the question pool. For example, it surfaces more situational questions if you're targeting a consulting role at McKinsey, or more technical depth questions if you're targeting a senior engineering role at a FAANG.

Please send it. Direct user feedback is the highest-signal thing we get. Email support@interviewexpert.ai and you'll hear back from a real person, not a templated reply.
