By no means am I taking credit for this. I have copied this over from the 9505 with permission from IRONMAN link to original thread

I will be maintaining this thread over here.....

As said per IRONMAN:

Hello, everyone. I have decided to make this Recommend-An-App thread so that YOU can share your favorite apps with everyone in this community.

****BUT THERE IS ONE CONDITION NO SUPER POPULAR APPS****

Don't post apps like PowerAMP and Flipboard and Swiftkey. EVERYONE knows about these apps.

The purpose of this thread is to make everyone aware of new apps which are largely unheard of. Apps which are not so popular. I was too tired of seeing numerous lists full of apps I already knew about.

So everyone, start posting! A brief summary would be appreciated (Unless the name is self-explanatory) as well as a PlayStore link (we all are too lazy to search for ourselves)

I will try to keep this list as up-to-date as possible.

1) Atom Launcher- A great launcher with many options for customization while maintaining a minimalistic look. I personally recommend Typo Black Theme to go along with it.

https://play.google.com/store/apps/...GwsMSwxLDEsImNvbS5kbHRvLmF0b20ubGF1bmNoZXIiXQ..

Typo Black Theme- https://play.google.com/store/apps/...oZXJleC50aGVtZS5OYW11U01vZGVyblR5cG9CbGFjayJd

2) WordWeb - In my opinion, THE best dictionary out there. Why? Because its offline. Doesn't require an internet connection!

https://play.google.com/store/apps/...53b3Jkd2Vic29mdHdhcmUuYW5kcm9pZC53b3Jkd2ViIl0.

3) Wallbase - I've tried 'em all and nothing has helped me find better wallpapers than this app. And most of them are full HD.

https://play.google.com/store/apps/...t=W251bGwsMSwxLDEsImNvbS5jaXRjLndhbGxiYXNlIl0.

4) LyricsPlayer - This app shows a notification on the status bar when you're playing music, clicking on it automatically searches for the lyrics and displays them.

https://play.google.com/store/apps/...EsImNvbS5saW5rLmFuZHJvaWQubHlyaWNzcGxheWVyIl0.

5) Holo Compass - The most minimalistic and cool looking compass around.

https://play.google.com/store/apps/...1bGwsMSwxLDEsInBsLnN1cml4LmhvbG8uY29tcGFzcyJd

6) Circle Alarm - A holo themed and minimalistic alarm app.

https://play.google.com/store/apps/...=W251bGwsMSwxLDEsImNvbS50amVhbm5pbi5hbGFybSJd

7) Node- Just a super cool live wallpaper

https://play.google.com/store/apps/...?t=W251bGwsMSwxLDEsImNvbS5zdWZmaWNrLm5vZGUiXQ..

8) Pimp My Music - This is great for fixing up the ID3 tags in your songs and for finding all the right cover art.

https://play.google.com/store/apps/...t=W251bGwsMSwxLDEsImF1LmNvbS5waWNrdXAucG1tIl0.

9) T.E.A.M. Battery Bar - This displays a coloured bar on top of the status bar showing the battery level (remember MIUI?). A must have for me.

https://play.google.com/store/apps/...=W251bGwsMSwxLDEsImNvbS5wdnkuYmF0dGVyeWJhciJd

10) Active Lockscreen - I think this is one of the best lockscreens out there.

https://play.google.com/store/apps/...wsMSwxLDEsImNvbS5jZWxsdGljay5sb2Nrc2NyZWVuIl0.

11) ConvertIt - Another holo themed and minimalistic app, this one is a unit converter.

http://xdaforums.com/editpost.php?do=editpost&p=42539176

12) Phone Addict - This great little app counts how many times I check my phone. Over a period of time, shows the day I checked my phone the most times, the least times, and how often I check on average.

https://play.google.com/store/apps/...5wYW5kdXRlY2hub2xvZ3kucGhvbmVhZGRpY3RmcmVlIl0.

13) Llama - For me this app is a MUST HAVE. I'll explain how it works. Basically, when you're at home or at work, your phone is getting signal from multiple cellphone towers nearby. What this app does is remember these towers and triggers certain profiles when they are in the vicinity. So, when I reach home, my phone automatically turns silent and when none of these towers are in range i.e. when I'm outside, it automatically increases the ring volume. You'll have to let it scan once, of course.

https://play.google.com/store/apps/...t#?t=W251bGwsMSwxLDEsImNvbS5rZWJhYi5MbGFtYSJd

14) Godville - This is a super simple game. You are God and you create your hero and lead him on quests etc. Superb time-killer.

16) Sensor Music Player - A music player which lets you use various sensors to change track, pause etc. For example, if I'm using my headphones and my phone is in my pocket, I can just tap my pocket to change the track. Pretty cool. eh?

https://play.google.com/store/apps/...51bGwsMSwxLDEsImNvbS56Z3VpLm11c2ljc2hha2VyIl0.
