What you can do in the app
Book, move or cancel in a few taps
Book live 60-minute sessions with your coach, or your free 30-minute trial. Move or cancel more than 24 hours before the start and you keep the credit.
Practise for your real interview
Behavioural, HR and technical rounds, including coding and system design. Your coach plays the interviewer and corrects your English line by line.
Upload your CV, we fill in your profile
Add your CV and the app fills in your profile for your coach. Keep different CVs for different roles and add the jobs you're applying for, so your coach prepares the right questions.
Message your coach between sessions
Send a question, a job description or an answer you want checked, and your coach replies in the app.
Written feedback after every session
See what went well and what to practise next, so the next session starts where the last one ended.
Reminders before each session
Push notifications remind you before every session, so you don't miss a booking across time zones.
Who's behind it
Real coaches, not an AI simulator
Every session in the app is with Sophie or Tom, British data engineers who coach interview English on Google Meet. They run the real round, then correct your English line by line and have you say it again.

Testimonials
What engineers say about Mockly
“Thanks to Mockly’s preparation and mock interviews, I passed multiple interviews, received several offers, and landed a new job. The sessions increased my confidence as we worked through initial screening and technical interview questions. Mockly didn’t just improve my English - they gave me great advice on how to answer questions and approach interviews strategically. I truly recommend them to anyone seeking a role at an international company.”
“Mockly has been the best investment I’ve made in the past year. The mentors don’t just have a deep knowledge of the language - they bring extensive experience in the IT industry. They understand the tech job market and are well-versed in modern engineering practices and the culture of top companies. Sessions aren’t just about improving your English; they’re an opportunity to sharpen your soft skills, gain valuable insights beyond engineering, and become a stronger communicator overall. Highly recommended.”
“Mockly knows what it takes to get hired. The preparation covers behavioral, algorithm, and system design interviews thoroughly - with real expertise in the STAR method, LeetCode, and Alex Xu’s system design frameworks. And when it comes to English and communication skills, the native-speaking mentors make all the difference.”
“Mockly’s approach is genuinely personalized - they use a variety of methods tailored to your specific needs. With their help, I improved my spoken English and prepared thoroughly for behavioral interview questions across different companies. This not only helped me refine my stories grammatically but also ensured I was using the right examples to answer specific questions effectively.”
“Mockly was a huge help in preparing for my interviews. We worked on both technical and behavioral questions, and I received great advice on how to approach them and what to focus on. I feel significantly more confident as a result. They also helped me with my CV and cover letter - showing me how to structure them properly and highlight my strengths. I appreciate that they always ask how you’d like to structure your sessions and adjust to your goals. It keeps you on track and makes the whole process far more effective.”
“I’ve had the pleasure of practicing English with Mockly and I truly appreciate the progress I’ve made. I highly recommend their services to professionals in tech and beyond. I particularly enjoy the teaching style and the philosophy behind it: “If you enjoy the process, you’ll get it.” The personalized learning plans make every session practical and useful. Their hands-on knowledge and genuine interest in the world of technology will genuinely boost your English skills.”
“Mockly has helped me enormously in working toward my goals in Tech. Highly recommended.”

FAQ
Questions about the Mockly English app
Does Mockly English have a mobile app?
- Yes. Mockly English has a free iPhone app called Mockly English on the Apple App Store, published by Speak Tech Eng Ltd. It lets you book live 1:1 interview English coaching, message your coach, get session reminders and upload your CV. You sign in with the same account as the website.
Is the Mockly English app free?
- The app is free to download and your first session is a free 30-minute trial with no card. After that, live 60-minute sessions cost $50 each, or less per session in packs of 5 ($237.50), 10 ($450) or 20 ($850). Credits last 12 months and work with either coach. There is no subscription for coaching.
Is there a Mockly English app for Android?
- Not yet. The app is iPhone only for now. On an Android phone, open app.mocklyenglish.com in your browser: you can book, message your coach and see your sessions there with the same account.
What is the best app to practise English for tech job interviews?
- It depends on what you need. General apps like Duolingo or ELSA build vocabulary and pronunciation but don't run a real interview. AI chatbots give unlimited practice but can't reliably judge a technical answer. Mockly English is built for one job: getting non-native engineers and data professionals through interviews in English, with a human coach who is a practising data engineer, runs the real round and corrects your English line by line. Many people use a general app or AI for daily practice and Mockly for live mock interviews.
Can I practise a mock interview in English on my phone?
- Yes. Book a session in the Mockly English app and join the call on Google Meet from your phone or computer. Your coach runs a behavioural, HR, coding or system design round and gives you line-by-line English feedback. For system design or live coding, a laptop is easier because you share a diagram or code.
Is Mockly English an AI app?
- No. Mockly English is live coaching with human coaches, Sophie and Tom, on Google Meet. The app is how you book and manage those sessions and talk to your coach. It is not an AI interview simulator, and it is not related to other products called Mockly or Mockly AI.
Who are the coaches in the app?
- Sophie and Tom, British data engineers who also teach English. Sophie has a first-class BSc in Mathematics from Cardiff University; Tom has a BSc in Mathematics and 8+ years teaching English to tech professionals. Together they have taught more than 2,700 sessions.
Who is the Mockly English app for?
- Non-native English speakers in tech: software engineers, data engineers, data analysts, product managers and engineering managers preparing for interviews in English, or who want business English for meetings, stand-ups and stakeholder updates.
Do I need a separate account for the app?
- No. Use the same email and password as the website. Your sessions, credits, messages and profile are the same on the app and the website.
How do I book my free trial in the app?
- Download Mockly English from the App Store, sign in or create a free account, choose Sophie or Tom and pick a time that suits you. The trial is 30 minutes on Google Meet, with no card. You get a calendar invite and the Meet link by email.
Can I cancel or reschedule a session in the app?
- Yes, in a few taps. Move or cancel more than 24 hours before the start to keep your credit. Cancelling later than that, or not showing up, uses the credit.
What does uploading my CV do?
- The app reads your CV and fills in your profile, so your coach knows your experience and the roles you want before the session. You can keep several CVs for different roles and add the jobs you're applying for, so sessions are built around those interviews.
Does the app work on iPad or Mac?
- The app is designed for iPhone. The App Store lists it as available on Apple silicon Macs and Apple Vision, but it is not optimised for them. On an iPad or computer, the website gives you everything the app does.
What data does the app collect?
- According to its App Store privacy label, the app collects your name, email address, user ID, purchase history and how you use the app, to run your account. Some usage data is used for analytics and is not linked to you. Details are in the Mockly privacy policy.
Is there a referral offer in the app?
- Yes. Refer a friend from the app: they get $10 off and you get a free session.
