Use of English PRO

I've leaned on Use of English PRO through B1 Preliminary all the way up to C2 Proficiency, and it's the one app I keep recommending. Hundreds of exams and thousands of assessments that feel like the real Cambridge papers, plus instant Writing feedback. The whole library is reviewed by professional English teachers, it stays ad-free, and your progress syncs between the phone and web apps.

Why Use of English PRO earned a permanent spot on my phone

I've tried a lot of Cambridge English prep tools, and most of them fall apart exactly where students need help most: the Use of English and Reading sections. Speaking and Listening come easier to many of us, but the grammar control and vocabulary precision those papers demand are what separate a pass from a near miss. Use of English PRO, built by Shining Apps LLC, is the resource I wish I'd found sooner. It closes that gap with sheer, well-organised volume.

The coverage runs across every Cambridge level: B1 Preliminary (PET), B2 First (FCE), C1 Advanced (CAE) and C2 Proficiency (CPE). What sold me is that it doesn't just throw tests at you. Content sits in tidy topic cards for Grammar, Reading, Vocabulary, Idioms and Phrasal Verbs, so a study session actually feels structured instead of random.

The practice volume is genuinely hard to beat

When people ask me how much material there is, I struggle to keep a straight face, because the numbers are almost silly. You get the complete Use of English parts 1 to 4 for all four levels, and the Writing and Speaking practice is where the app quietly outclasses the other apps I've tried.

• Use of English: over 400 exams built from more than 1,500 individual assessments across open cloze, word formation and key word transformation.
• Reading: 200+ exams with over 1,000 targeted assessments to sharpen comprehension and gist.
• Writing: 300+ writing exams paired with an Immediate Feedback engine, so you see what to fix straight away instead of waiting on a tutor.
• Speaking: over 200 speaking exams to build verbal confidence before the face-to-face test.
• Grammar Zone: 200+ exercises holding more than 3,000 assessments, plus integrated level tests to track where you actually stand.
• Vocabulary depth: 26 deep-dive topics covering collocations and phrasal verbs, with 80 specialised exercises per topic.
• Listening: full practice for PET, FCE, CAE and CPE, including 50 casual situation tracks for real-world comprehension.

There's also a built-in English dictionary for instant lookups while you practise, 28 fluency-building texts with their own exercises, and everything is reviewed by professional English teachers. That last part shows in the quality of the answers and explanations.

Study anywhere and get real answers fast

This is the bit I appreciate most as someone who reviews these apps for a living. Everything syncs across mobile and the web-app through your account, so you can start a Reading paper on your phone on the bus and finish it on a laptop at home without losing your place. The interface stays clean and ad-free, which matters when you only have twenty minutes to study and don't want anything getting in the way. And on the rare occasion I've had a question, the support team has been quick and genuinely helpful, usually replying within a day with a real answer instead of a canned reply.

Who I'd hand this to

If you're serious about your Cambridge certificate and you want one clean, ad-free place to drill grammar, vocabulary, phrasal verbs, idioms and full exam papers, this is my default recommendation. The interface stays out of the way, the volume keeps you busy for months, and the instant feedback on Writing and Speaking turns weak spots into strengths. You can explore it at useofenglishpro.com. It's available on iOS, Android and the web, and it made my own exam prep feel far less daunting.
