This is Emma from a start-up company named iSing. I followed Techtrickz site for years and really like the articles you write. So, today I sincerely invite you to review our free Android app named iSing Karaoke. It's an app which allows you to sing songs along with karaokes on your smartphone and record your songs in both MP3 and MV mode. It covers more than 100,000 songs in English, Hindi (coming in this week), Japanese, Chinese, Taiwanese, Thai and Portuguese. It now ranks Top 10 in Music&Audio of Google Play Store in Taiwan, according to AppAnnie. I think once the Hindi songbooks gets online officially, thus iSing Karaoke becoming the first karaoke app supporting Hindi language, it's about to get popular in India. How do you think?
