The Google Play Android App store has over 1M apps but there are a handful of apps I found really useful in 2014 and they tend to be the first apps on a new phone and the apps I use most often.
1 - Drippler
Drippler is a neat little app that provides reviews, tech tips, updates and app recommendations in a well designed easy to use Android app. This app is a must for anyone interested in Android.
Drippler will provide tips and app suggestions based on the device it is running on. It's simple and straight forward.

2 - Slice: Online Shopping Tracker
Slice is a helper app for anyone that makes purchases online (and who doesn't). At it's core, it is a fantastically full featured package deliver tracker that has push capabilities (no more checking 5 online package tracking websites). It supports most major US package delivery carriers such as : USPS, UPS, FedEx, DHL, OnTrac, Lasership, Prestige, Ensenda, and more
In addition to tracking packages, it tracks recalls to see if anything you bought has been recalled or if the price has dropped (helping you claim under price match policies).
If you are in the US and use Android, you should download this now.

3 - Agent - do not disturb & more
Anyone that has met me in the last year, that uses a non Motorola Android device has heard me recommend this app. It is a must. Everyone that tries this app loves it.
It basically gives you some of the functionality that has made Motorola phones so popular. It is a smart background agent that automatically changes phones settings to save battery, prevent distracted driving, remembers where you parked, silence your phone when you are in meetings or sleeping (except for urgent calls), etc.
The Drive Agent is triggered by your cars bluetooth connection or by the motion of your car. It can be configured to read your SMSs, allow you to respond by voice or auto-respond to callers/texting letting them know you can't answer now because you are driving.
The Battery Agent is triggered when your battery drops below a certain threshold and allows you to turn off blutooth, dim the screen, etc. Everything comes back to "normal" when you charge your device automagically.
Meeting Agent knows when you are busy (based on your calendar) and then switches your phone to either silent or vibrate. You can specify your work week (days/hours) so it only applies during these windows.
Sleeping Agent allows you to automatically silence your phone when sleeping. You can configure different times for different days. It can auto-respond to callers/texters letting them know you are sleeping. You can specify which contacts can "wake" you.

4 - Time Hop
There was a fantastic online picture storage service (now gone) called Everpix. One of the coolest features they had was a flashback feature where you received an email everyday highlighting a picture from that day a week ago, a month ago, a year ago, etc. It was a great way to relive some of your past moments captured in photos.
Time Hop is a similar concept except it does this for all your social media networks. It brings back this day from your past by surfacing posts and pictures from your various networks: Phone, Facebook, Instagram, Twitter, and Foursquare.

5 - Lastpass
With all the hacks and breaches, you should already be using long unique passwords for each internet site you are registered with. Obviously keeping all of those in your head doesn't work otherwise your passwords aren't unique enough. Enter LastPass. It is a fantastic cross platform password manager that costs just $12 a year.
6 - Evernote
I love Evernote and everyone should have it, use it and love it.
