The best interview prep apps are CoPilot Interview for mock interviews built from your résumé and the job description, with each spoken answer scored out of 10 (we make it), Huru for unlimited free video practice on an iPhone, Big Interview for a structured course with iOS and Android apps, and LeetCode for coding practice on your phone. Aced (formerly Exponent) and interviewing.io are the strongest web options for peer and technical mock interviews, and ChatGPT or Gemini voice mode is a free fallback on any phone.
Disclosure: we make CoPilot Interview, the first app on this list. Everything we say about the other apps comes from their own websites and app-store listings, checked in October 2026. Prices and free tiers change often, so confirm them before you pay.

Which interview prep apps have phone apps?
Of the nine, five run as phone apps: Huru (iPhone and iPad), Big Interview (iOS and Android), LeetCode (iOS and Android), ChatGPT and Gemini. The other four are web or desktop tools. The split matters less than it sounds: answering out loud and hearing what to fix works best at a desk anyway.
| App | iPhone | Android | Web browser | Desktop |
|---|---|---|---|---|
| CoPilot Interview | No practice app; use the browser mock | No practice app; use the browser mock | Browser mock: 113 questions, 9 tracks | Windows and macOS: full Mock Interview |
| Huru | App (iPhone and iPad) | No app; its FAQ points to the web app | Yes | Use the web app |
| Big Interview | App | App | Yes on a computer; mobile browser not supported | Use the web version |
| LeetCode | App (iPhone and iPad) | App | Yes | Use the website |
| Aced | None listed | None listed | Yes | Use the website |
| interviewing.io | None listed | None listed | Yes | Use the website |
| Yoodli | None listed | None listed | Yes | Not on its pricing page |
| ChatGPT | App | App | Yes | Yes |
| Gemini | App | App | Yes | Listed as Gemini for desktop |
A phone is good for short reps: one coding problem on the train, a voice drill on a walk. It is weak for anything that needs a keyboard or a full screen, such as writing a full solution or sketching a system design. Treat phone sessions as the warm-up and desk sessions as the real mock interviews.
The 9 best interview prep apps, reviewed
1. CoPilot Interview: best for scored mock interviews from your own résumé
What it does: CoPilot Interview is a desktop app for Windows 10+ and macOS 12+. Its Mock Interview mode reads your résumé and the job description, then builds the interview: you choose the level, 3, 5 or 8 questions, and the mix of behavioral, technical, system design and coding. It reads each question aloud, listens to your spoken answer and scores it out of 10 with what to fix and a model answer, then ends with a report card. If you'd rather not install anything, the free browser mock interview has 113 real questions across 9 tracks, from behavioral to SQL and security.
Strengths: the questions name your actual projects and the stack in the posting, which generic question banks can't do. Free tools sit alongside it, including the STAR story builder and the coding interview cheat sheet.
Limits: no phone app for Mock Interview, and the free plan caps you at 15 minutes a day. Pair it with at least one session in front of a real person.
Price (as of October 2026): free plan with 15 minutes every day, no card and no signup; Standard $14.99/mo (sale; regular $19.99) for 60-minute sessions, up to 100 minutes a day; hour packs from $5.99. It is not affiliated with Microsoft Copilot or GitHub Copilot. The AI interview app page lists what runs on each device.
Who it fits: anyone with a specific job in view who wants daily spoken reps, including technical rounds.
2. Huru: best free video practice on an iPhone
What it does: Huru asks interview questions, records your spoken answers on camera and scores each one out of 100, with feedback and a stronger version of the answer. Its site says the score weighs relevance, structure, specificity, impact and ownership, and articulation. A Chrome extension turns a job post into a custom mock interview.
Strengths: as of October 2026, every job-seeker feature is free with no subscription, and there is an iPhone and iPad app on the App Store. The debrief includes a STAR table showing which parts of each answer you covered.
Limits: no Android app (its FAQ sends Android users to the web app), no human feedback, and no code editor for coding rounds. Our Huru AI review covers the details.
Who it fits: zero-budget job seekers who want as many recorded reps as possible.
3. Big Interview: best course-style app with iOS and Android
What it does: Big Interview combines about 170 video lessons, an interactive answer builder and an Interview Simulator that gives AI feedback on recorded video answers, covering delivery, body language and content. Its support guide says the official iOS and Android apps let you practice questions and record answers on your phone, complete assignments and track progress.
Strengths: the most structured teaching on this list, and the only dedicated interview-coaching app on this list with both iOS and Android versions.
Limits: no free plan or trial on its pricing page as of October 2026. You must register on the desktop version before using the app, résumé tools are desktop only, and practicing in a mobile browser is not supported.
Price (as of October 2026): $39 for 30 days, $99 for 3 months or $299 one time for lifetime access, with a 30-day money-back guarantee. Many colleges and workforce programs license it, so ask your career center before you pay. See our Big Interview review.
Who it fits: career changers and returners who want lessons first, then recorded practice on any device.
4. LeetCode: best for coding practice on your phone
What it does: LeetCode is the standard coding problem bank. Its iOS and iPadOS app, published by LeetCode on the App Store, lets you search company questions, practice problems, manage lists, track progress with widgets and register for contests. LeetCode LLC also publishes an Android app on Google Play.
Strengths: the standard place to build a coding habit, and a phone app that makes a daily problem easy.
Limits: it trains problem solving, not talking through a solution under time pressure, which is what the interview grades. Typing full solutions on a phone is slow, so treat the app as review and warm-up.
Price (as of October 2026): free account; Premium is $35 a month (shown as a discount from $39) or $159 a year, adding company-tagged questions, premium content and timed Interview Simulations. Our guide on whether LeetCode Premium is worth it does the math.
Who it fits: software engineers building a daily coding streak. For the wider coding stack, see our list of the best coding interview prep tools.
5. Aced (formerly Exponent): best for courses and peer mock interviews
What it does: Aced, the company formerly called Exponent, sells courses for product management, software engineering, system design, data and other tech roles, and runs Aced Practice, the peer mock interview service that replaced Pramp. Peer sessions cover product management, data structures and algorithms, system design, behavioral, SQL, data science and ML, frontend and investment banking.
Strengths: real people to practice with, plus a question database and video answers on paid plans.
Limits: web only; we found no phone app on its site. AI mock interviews and AI interview feedback sit on the top Expert plan.
Price (as of October 2026): Basic $0 with sample lessons and 5 peer mocks a month; Pro $79 a month or $12 a month billed annually; Expert $99 a month or $20 a month billed annually. Its FAQ offers full refunds within 5 days of purchase. More in our Exponent (Aced) review.
Who it fits: tech candidates, especially product managers, who want frameworks and a human partner.
6. interviewing.io: best for FAANG-style technical practice
What it does: interviewing.io runs anonymous mock interviews with engineers from large tech companies. Its free AI Interviewer conducts coding and system design interviews in the style of a FAANG mock, and you can work through more than 200 problems from Beyond Cracking the Coding Interview for free.
Strengths: a technical round with a real engineer from a large tech company.
Limits: web only, technical rounds only (the AI Interviewer doesn't cover behavioral), and human sessions are expensive.
Price (as of October 2026): human mock interviews start at $179, depending on the subject and whether you want an interviewer from a specific company. See our interviewing.io review.
Who it fits: engineers facing a big-tech onsite who have done their volume practice elsewhere.
7. Yoodli: best for delivery feedback in roleplays
What it does: Yoodli runs AI roleplays: you choose the role you're preparing for, answer interview questions and dynamic follow-ups in a simulated conversation, and get feedback on your answers and delivery, including pace and clarity.
Strengths: follow-up questions, which most question banks skip, and coaching on how you sound.
Limits: the company now positions itself mainly for sales and training teams, the free tier is small, and its pricing page lists no phone app. Our Yoodli review covers the shift.
Price (as of October 2026): Starter includes 5 lifetime roleplay sessions; Pro is $8 a month billed annually for up to 10 roleplays a week; Advanced is $20 a month billed annually for unlimited roleplays.
Who it fits: people whose content is fine but whose delivery, pace or filler words let them down.
8. ChatGPT voice mode: best free fallback on any phone
What it does: ChatGPT is a general AI assistant with apps for iOS and Android and a web version. You can set it up as an interviewer: paste the job description, ask for one question at a time and answer out loud by voice.
Strengths: free to start, on every device, and flexible about role and question type.
Limits: as of October 2026 the Free plan lists limited voice chats, and you have to design the session and the scoring yourself. Our ChatGPT voice mode interview practice guide has setup steps and prompts.
Price: Free plan available; for Go, Plus and Pro prices, see the vendor site.
Who it fits: anyone who wants quick spoken drills on a phone at no cost.
9. Gemini Live: free voice practice in the Gemini app
What it does: Gemini Live is the voice conversation feature inside the Gemini app. Google describes it as a back-and-forth voice chat you start by tapping the Live icon. The Gemini app is available on Android and on iPhone.
Strengths: a natural conversational feel, and you can interrupt or change direction mid-answer.
Limits: no interview structure or scoring unless you prompt for it, and Google notes that some features require setup or a subscription.
Price: free app; for paid Google AI plans, see the vendor site.
Who it fits: Android users who want a free spoken practice partner.
Google Interview Warmup, once a common pick on lists like this, was retired in April 2026, so it is not included.
How we chose these apps
We looked for apps that help you rehearse, not apps that only list questions. For each one we compared the published features, free tier, price and platforms on the vendor's own website, support pages and app-store listings in October 2026. We did not test them hands-on or run user surveys, and we don't report ratings or download counts. We gave weight to four things: spoken practice, feedback that says what to fix, a free option you can use for a week, and a plain answer on where it runs.
Every app here is a practice tool. If your interview itself is a phone call, our phone interview tools comparison covers call setup separately. For apps focused purely on AI interviewers, see the best AI mock interview tools.
Which interview prep app should you pick?
- You have a specific job and a week or two: run a CoPilot Interview Mock Interview from the posting each day, and redo your two lowest-scoring answers the next day.
- You only have a phone: Huru on an iPhone; on Android, Big Interview if your school licenses it, or ChatGPT or Gemini voice for free drills. CoPilot Interview's browser mock also opens without an install.
- Software engineering: LeetCode for daily problems, interviewing.io's free AI Interviewer for coding and system design, then one human mock before the onsite.
- Product management or data roles: Aced for frameworks and peer mocks in your track.
- You want lessons before practice: Big Interview's course and answer builder.
- Your delivery is the problem: Yoodli roleplays or Huru's recorded answers, played back.
- Zero budget: combine Huru, CoPilot Interview's free 15 minutes a day, interviewing.io's AI Interviewer and Aced's 5 free peer mocks a month. The free interview prep tools fill the gaps.
Most people do best with two apps: one for daily spoken reps and one that puts a real person or problem in front of them.
