Get freedom from your phone’s obvious limitations. Use 504 لغت ضروری ( آموزش زبان انگلیسی ), made by Smart-Ideas, a Education app on your PC or Mac with BlueStacks, and level up your experience.
Honestly, 504 لغت ضروری feels like one of those must-have apps for anyone trying to beef up their English vocab, especially if they’ve heard about that classic “504 Essential Words” book. It’s got all those important words laid out in neat categories, and the lessons are broken up to make things manageable—not overwhelming. What stands out is how the app mixes things up with quizzes and questions alongside each lesson, so it isn’t just dry reading. There’s the English word, its meaning in Persian, example sentences, and even audio to help with pronunciation (and it’s not just one voice, so it doesn’t get monotonous). The layout is really simple and straightforward—easy on the eyes, not distracting. There’s also this feature that tracks progress, which makes it easy to see what’s left and what’s been covered.
They’ve built in repetition, so each word pops up multiple times to actually stick, not just get memorized for a minute and forgotten. The examples are practical, too, pulled from the standard textbook but with Persian translations right there, which helps a lot. The quizzes go both ways, asking for English-to-Persian and vice versa, making sure nothing gets skipped. Running it on a big screen with BlueStacks is actually handy if tapping on a phone isn’t your thing—so it works well for folks who prefer learning at a desk. Overall, it keeps everything direct and focused, without clutter, so it does exactly what it says: help make those 504 words second nature for learners.
Switch to BlueStacks and make the most of your apps on your PC or Mac.
