While I am sure apps like Facebook, Twitter, WhatsApp and Google Maps are the often used and must have apps, I am listing down other lifetsyle and productivity apps. Pl feel free to add your recommendations as comments.
Expense Tracker
Taking the time to track and analyze your income and where it's going is a crucial element of managing your personal finances. That's because doing so uncovers hidden money leaks so you can better allocate your resources, thereby ensuring you always get the most out your paycheck. It makes it easier to set financial goals, too.
Of course, if you want to track your expenses, you have to record them somewhere. Try Spending Tracker

Fitness Apps
Keep track of your weight fashionably with Carrot Fit or Carrot 3. It is only for people who love humor. The app is filled with sarcastic insults pushing you to lose weight. I find it entertaining and motivating. Download this app at http://www.meetcarrot.com/alarm/ [Only available for iOS]

Period Tracker ios version / Android version
Track your periods with a press of a button. Lots of apps predict your period’s monthly due date. But Period Tracker doesn’t base its projections on the standard, 28-day calendar—since so few women’s bodies actually adhere to it. Instead it will take out the average of your last three months’ menstrual cycle to predict the start date of your next period. Apart from your current and the future period dates, you can also know about the ovulation and the fertile days, the moods that you are going to witness and the symptoms in a simple month-view calendar. You can download here ios version / Android version
Mommies who use educational apps, should try The Honor Roll. The app was previously released as "Moms With Apps" and has been redesigned, refocused and renamed "The Honor Roll". It is now an expertly annotated and curated catalog of apps covering all developers in the entire iOS app store as opposed to a subset of developers.
