One of my favourite apps right from the start was PHOTOBEAMER (which allowed you to stream your photo libraries on your phone to any internet-enabled display).   Nokia has released PLAY TO now which goes a step further and allows for streaming of all audio/video content from your phone to any DLNA device in the home.  Two of my favourite windows-phone (albeit Nokia-exclusive) apps for sure.

Package Tracker

If you ship or receive packages on a regular basis this a must-have app for keeping track of them.  It supports over 60 carriers and also syncs with the Windows 8 app.  It supports Live Tiles and you can pin specific packages to the start screen.  It costs $2.49, but well worth it.

The Nokia Black update is rolling out today with several new features and improvements.  My favorite is the App Folder app which lets you put groups of apps in a single folder, much like how you do on iOS.

If you have the update through the developer preview updates, you can also download the App Folder app from the Windows Store.

Oops, I misread the OP to say Windows Phone Thread, I missed the word app. 

Yeah, I don't care anything about Android, or Google for that matter.

i have the Folder app. it works like a champ. as for android already doing it, wp will too with the Black update. i doubt android did it at the beginning of its existence either. i am completely happy with WP and my 920. when my contract expires in december 2014, i'll get a new phone with a larger screen. an example would be the 1520. what a great phone! my ex has one and my son-in-law is considering one, also.

Yeah, same here!  I had an Android phone and didn't like it much at all.  I keep hearing people saying that Android has this and that app/feature that Windows phones don't have, but my 820 does all I need it to and all the apps I want or need are available in the Windows store.  For mine, the W8 phone has a much nicer interface and is more user friendly than Android, and I'd never consider an Apple phone.  While there are some advantages to having an Apple phone with my home network [dedicated networkapps and abitities not yet available on Windows phones] they're just not enough of a magnet to draw me in.

I just checked regarding the 'Black' update and it is not yet avaiable here on my network.  It's available to some of the other models and networks but it hasn't been approved for the 820 on Vodaphone as yet.

I'm looking into getting a Lumia 520 to synch up with my home phone and internet connection, which are through Telstra.  I can get one on a plan for an extra $12.00 a month over 12 months or a PAYG one for $139 outright.  While the plan costs a tad more, there are advantages going that way... eg, lower call costs; more included features/options and never having unused credit expire.

Yes, and I really need to make better use of the available apps and my user account options.  While I use some of the obvious, there is so much more I could be using to better enjoy my W8 phone.

Thanks for the head up, ID.

I've posted several times now about a Nokia exclusive app called 'Photobeamer'  (see my first post in this thread), but recently there is yet another Nokia exclusive app I've been finding invaluable.

Nokia Beamer

This app shares your phone screen (Nokia phone) via Nokia's servers to/with any internet-enabled screen locally or remotely (for remote sharing you send people the link via SMS or email etc.).  You can even invite additional 'participants' (although I'm not sure how many since I have yet to test that particular app feature!).  If you choose you can also share your camera feed so anyone on the other end can see whatever your phone camera is 'seeing'.

Of course it is advisable to be using WiFi (to save data) while doing so but the app also has options regarding quality vs speed and one can set it to either share the screen constantly or only when one gives the screen a shake (thereby only providing periodic screen updates).

Absolutely fantastic app I've used quite a lot already.  Aside from how rock solid I've found the Nokia hardware I continue to be impressed by Nokia's focus on bringing out more and more worthwhile apps!

Now this is an app I will find very useful.... when I can get 8.1 on my phone.  I got the Black update about a week after folks here were speaking about getting it, so hopefully 8.1 isn't too far off.

Ok, okay!  So it's just the developer preview people are talking about having.  Oh well, I'm not missing out after all.  Still, I will look into the developer preview and see how it goes.  I have a vague recollection that some folks had issues, so hopefully it will be easily rolled back if that happens to be my experience with it.  Uh, no... I just read at the Dev site that the updates delivered are not reversible.  Never mind, I'm sure it'll all work out just fine.

It's Okay, I figured it out/solved it.  I hadn't completed the registration properly. Once I had I was able to enable the preview and get the updates.

Yeah, it was all so confusing, but after being up for 32 hours now without sleep, I'm allowed to get confuseded... and not see the obvious.

Anyway, all is well that ends well, my phone is updating and I can now get the tools to make my own apps.  Woohoo, with a bit of practice, a wing and a prayer, I'll hopefully be able to make apps that'll connect me to my internet banking [they do Android and Apple apps but not one for Windows] and another to connect me to my ISP and landline provider accounts.
