A Free AI Interview Assistant App for Android: CoPilot Interview's Phone Companion (Beta)

What the Android beta does, how to install the APK safely, what stays on the desktop app, and how to use your phone to practice anywhere.

Yes, there is a free AI interview assistant app for Android: CoPilot Interview's phone companion, now in beta. It runs on Android 10 or newer, comes as an APK of about 8 MB from copilotinterview.com rather than from Google Play, and does the core job of the desktop app on your phone. It listens to a question through the phone's microphone, captions it live and shows a structured answer you can learn from.

It is a companion, not a replacement. Phones can't capture system audio or screens, so the screenshot tools and the floating answer window stay in the Windows and macOS app. Where the phone version shines is practice: rehearsing answers out loud wherever you are, running drills with a friend, and getting ready for phone screens when your laptop isn't with you.

Below: who the app is for, how to install the APK safely, what works on the phone versus the desktop, the free plan and privacy basics.

What the phone companion does

The phone companion is CoPilot Interview on your phone. Put the call on speaker, or keep the phone near the laptop the call is on, and the app listens, transcribes and answers the way the desktop version does: it hears the question through its own microphone, shows live captions so you can check what was asked, and returns a structured answer you can compare with your own.

"Beta" means what it says: the app is newer than the desktop version, it isn't on Google Play yet, and features may change. If you want everything today, including the four modes, Dual AI Mode and a coding mode that can read a pasted screenshot, the desktop app is the complete free AI interview assistant. The phone app covers the listening-and-answering core.

One technical point matters before you plan around it. Android gives an active phone call priority over the microphone: according to Android's documentation on sharing audio input, the call always receives audio, and other apps that were capturing usually receive silence. So don't count on the app hearing a call you take on the same phone. Take the call on another device, such as your laptop, a second phone or a landline, on speaker, with the companion phone beside it.

Who the Android app is for

Start with the desktop app instead if you're preparing for coding rounds and want a problem read from a screenshot, if your interview is a video call on the same computer, or if you use an iPhone, since that version isn't out yet.

How to install the Android APK safely

Because the app isn't on Google Play yet, you install it like any APK: download the file, let your browser install apps once, then turn that permission back off. Menu names vary a little between phone makers.

  1. Check your Android version. In Settings, open About phone (Software information on some phones). You need Android 10 or newer.
  2. Download from the official page. On your phone, open the download section on copilotinterview.com and tap Download for Android (APK). The file is about 8 MB.
  3. Expect a browser warning. Browsers warn about APK downloads in general, because any APK can install software. What matters is that you got the file from the official site.
  4. Allow installs from your browser once. When you open the file, Android says your phone isn't allowed to install unknown apps from this source and offers a Settings shortcut. Turn on the permission for your browser only, then go back.
  5. Install and open the app. If Google Play Protect offers to scan it, let it; Play Protect also checks apps from outside Google Play. Grant the microphone permission when asked, because that's how the app hears questions.
  6. Turn the install permission off again. Go to Settings, then Apps, then Special app access, then Install unknown apps, choose your browser and switch it off. The app stays installed.
Tip: Only install the APK from copilotinterview.com. If you come across a "CoPilot Interview" APK on a mirror site, in a forum or in a chat message, don't install it. You can't verify where it came from, and the official download is free anyway.

Google Play doesn't update apps it didn't install, so get newer beta builds from the same official download page.

What works on the phone vs the desktop app

Both apps hear a question and give you a structured answer, but they hear it in different ways, and that decides which features each one can offer.

Best forPractice anywhere and rehearsing audio-only phone screensFull sessions, coding rounds and scored mock interviews

In short, the phone listens the way a person in the room would, which is fine for practice and calls on speaker. The desktop app reads the meeting audio directly and runs in its own window beside Zoom, Microsoft Teams, Google Meet, CoderPad and HackerRank, which makes it the full real-time interview assistant. Our system requirements guide explains why system-audio capture matters on a computer.

Follow the rules of the employer or assessment you're in — many people use it only to practice, which works on the free plan.

Practice drills you can run on your phone

The phone app works best as a practice partner you carry with you. Each drill takes 10 to 15 minutes, so one fits inside a free daily session.

1. The in-person drill

Ask a friend to read you questions from a list while the phone sits between you. Answer out loud first, then check the captions and the structured answer. Note one point the answer covered that yours didn't, and answer again.

2. The speaker-call drill

Have a friend call your laptop or a second phone, put that call on speaker, and keep the companion phone nearby. Run a mock recruiter screen: "walk me through your résumé", "why this company?" and "what are your salary expectations?" Our technical phone screen guide covers the coding version of the same call.

3. The solo read-aloud drill

Read a question aloud, pause, answer it, then compare. It's less realistic than a partner but works anywhere quiet. Behavioral questions suit it well: a conflict with a teammate, a project that failed, a call you made with incomplete information. After each answer, check that yours had a clear first sentence, one specific example and a result; if the app's answer is organized differently, retell your story in that structure.

Tip: Practice somewhere quiet. The app hears through the phone's microphone, so a TV, traffic or a busy café makes the captions less accurate, and the answer can only be as good as the question it heard.

Back at a computer, move up to a scored session. The desktop app's AI mock interview builds questions from your résumé and a job description, reads them aloud, scores each spoken answer out of 10 with what to fix and a model answer, and ends with a report card. For more solo formats, see mock interview practice without a partner.

Privacy on your phone

CoPilot Interview's site FAQ describes the data flow: audio is streamed in short encrypted segments through our proxy to a speech-to-text model, and the question text goes to the AI model you chose. Nothing is kept on our servers beyond the request, and on the desktop app your session files stay in your own Documents folder. The security page and privacy policy have the details. On the phone itself:

iPhone and other Android options

An iPhone version is coming soon, with no date to share yet. On an iPhone, use the desktop app on Windows or macOS for now, or open the free in-browser demo to see how it works.

FAQ

Is there a free AI interview assistant app for Android?

Yes. CoPilot Interview's phone companion is in beta for Android 10 and newer. It listens through the phone's microphone, shows live captions and returns a structured answer. The download is free, and the Free plan gives you 15 minutes every day with no credit card.

Why isn't the CoPilot Interview app on Google Play?

It's in beta and isn't on Google Play yet, so you download an APK of about 8 MB from copilotinterview.com. Your phone asks you to allow installs from your browser once, and you can turn that setting off after installing.

Is it safe to install the CoPilot Interview APK?

Download it only from copilotinterview.com, never from a mirror site or a link someone sends you. Allow installs for your browser only, let Google Play Protect scan the app if it offers, and switch the install permission off afterwards.

Can the Android app read a coding problem from my screen?

No. Phones can't capture system audio or screens, so the screenshot tools stay in the desktop app for Windows and macOS, whose coding mode can read a pasted screenshot of a problem.

Can I use the Android app for a phone interview?

It hears questions through its own microphone, so take the call on another device, such as your laptop or a second phone, on speaker. Follow the rules of the employer or assessment you're in. Many people use it only to practice, which works on the free plan.

Is there an iPhone version?

Not yet. An iPhone version is coming soon. Until then, use the desktop app on Windows or macOS, or try the free in-browser demo.
