Everyone could use some grammar help now and then—and a host of new apps are ready to lend a hand, says New York Times tech reporter Kit Eaton. He found the most polished of those he tested to be the Practice English Grammar from Cleverize. It works on iOS and Android devices and provides quizzes and flash cards on a range of grammar topics. The core app is free, but different learning modules are $1 each, or you can subscribe for $10 a month.
Other apps Eaton tested and enjoyed include LearnEnglish Grammar from the British Council, available in both British and American English; English Grammar Test by SevenLynx; Grammar and Practice for Business by HarperCollins; and Grammar Up from Webrich Software.
