Every new user gets 3 hours of full AI coaching free, to use within 7 days of starting. 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, to use within 7 days across as many sessions as you like. When the 3 hours or the 7 days 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.

The recording of your spoken answer is uploaded to our servers to score your pronunciation and delivery, and is deleted within 7 days by default. We keep it for longer only if you turn on saved recordings so you can play back past answers. Live transcription runs through Apple's Speech framework — on-device where available, though Apple's servers may assist for some languages and devices — and your transcript and speaking metrics are sent to our backend for AI coaching. You can ask us to delete your recordings at any time at interviewexpert.ai/delete-data. Full details in our Privacy Policy.

Yes, anytime. In the iOS app, Settings → Delete all my data deletes everything — the data on your phone and everything held under your device ID on our servers, stored recordings included — apart from your entitlement and anonymous analytics events, which are kept on purpose. If you no longer have the app installed, email support@interviewexpert.ai and we'll delete it for you. Full details at interviewexpert.ai/delete-data.

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.

Yes — the Android app is live on Google Play now. Search "Interview Expert" or use the Google Play button on this site to install it. We started with iOS because consistent hardware let us get speech recognition and feedback quality right first, and Android followed once that bar was met.

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 tell us directly. Real user feedback is what decides what we build next. Email support@interviewexpert.ai and you'll hear back from a real person, not a templated reply.
