As the number of apps in the Windows Phone 7 marketplace zooms past 10,000 I thought it worth a quick summary of the apps that I use most. Almost certainly there are loads of great apps that I’ve missed, so feel free to let me know if you are aware of something amazing that I should be aware of. And also I realise that this list will get out of date pretty quickly given the avalanche of apps that are hitting the store. If I can make the time I’ll try to update it once in a while.

These aren’t exhaustive reviews by any means, just brief descriptions to give you a flavour. They are UK biased as I’m UK based, and listed alphabetically:

App Name	Price	What is it?	Why do I like it?
Amazon Kindle	Free	eReader. It’s a no-brainer if you already own a Kindle device	Great reading experience, just flick left or right to turn the page, access all of your Kindle books. Keeps track of your position and syncs seamlessly between Kindle device and phone so you can read on Kindle, then pick up the spot you left off on the phone, then the Kindle resumes where you left off from the phone etc. Simply fantastic. Great use of the cloud, this kind of app is the future
BBC News Mobile	Free	News reader from BBC news website	Slick presentation, easy-to-read format. Breaking news pushed to Live Tile
Chicks n Vixens	Free while in beta	Game. Very similar in concept to Angry Birds. Get it while it’s still free!	Huge fun! You get to fire chickens from a cannon at foxes (vixens) across a range of locations and lots of fiendish levels
Facebook	Free	Official Facebook app for WP7	Kind of a no-brainer app. Nice presentation, easy to use, feature rich, nice use of WP7 UI. Needs live tile support though
Flixter	Free	Film database	Nice presentation with lots of useful information. Live Tile support. The IMDB app is very nice too but Flixster just has the edge for me
ITN News	Free	News app from ITN	Has much more video content than the BBC news app and is presented very nicely. Good alternative especially if you’re on a wi-fi connection for video news
Last.fm	Free	Streaming music	I love the way this keeps in sync with Last.fm on the Xbox and on the website. Excellent for just entering a tag that suits your mood and getting great music streamed to you. No subscription required for Windows Phone 7 users!
Putt In Golf	99p	Crazy golf in 3d, 18 holes	I love two specific things about this game: The graphics and the control mechanism. Lush environment and good range of options makes for a fun game. Could do with a couple more courses though
Send to WP7	Free	Send any file to your WP7…as the name suggests. This is an AWESOME app	I absolutely love this app. Here’s an example of how I use it: I right click on a Word doc on my Windows desktop and choose “Send to WP7”. Within a couple of seconds I get a notification on my phone that the file is available. I tap on it and it opens in Word on the phone, I can either read it or edit it. Same for spreadsheet, presentations, and in fact just about any file. Absolutely genius, everyone should have this app. Live Tile support
Sky Mobile	99p	Sky TV listings with remote record option	Nice way to browse what’s on Sky. Listings can be cached for offline (and much faster) use; Can choose to record any programme right from your phone, great for those “I forgot to set up to record [insert your favourite programme]!” moments
Stock Alert - Live!	79p	Display stock prices right on the tile with live updates	Simple enough: choose the stocks you want to follow and get the usual detail about them. Key for me though is that the Live tile is updated so you can see the stock price right on your home screen without even opening the app. Really useful
Tech Track	Free (ad-supported version)	Technology news from various sites	Pretty simple but effective, nice way to keep up to date with what’s happening in the Tech world
Tube Run+	79p	London Underground information and maps	There are a few of these kind of apps around, this is my favourite at the moment. Live tile support to show how your chosen line is running. Also makes it easy for you to claim compensation for late running trains!
Translator+	Free	Uses either Bing or Google translator	Simple but very effective way to translate text. Switch between Bing and Google to translate between 30 languages. Downside is that it requires a data connection and if you’re roaming you’re probably going to have switched this off. And of course, when you’re roaming is when you need a translator…but you takes your choice I guess
Weatherbug	Free	Weather information with live tile support	Two things separate this from other weather apps I’ve seen: Live tile shows the weather in your chosen location without you having to open the app. And push notifications advise you of extreme weather events, again without you having to open the app.
WikiPanda	Free	Wikipedia reader	This is the nicest one I’ve seen. Search is predictive which makes it very quick to enter, and your previous searches are listed for easy reference. The Wikipedia entries are laid out in an easy-to-read format. I use this app a lot!
World Radio	79p	Streaming radio stations from around the world	Two things sets this app apart from others I’ve seen: Really great range of radio stations, and very good at streaming. Maybe I’ve just been lucky but I find the streams seem very stable and will run for hours without pausing

So which apps am I missing from this list? Let me know! I am always on the hunt for great apps. I know I’ve left of loads of good games, but I had to draw the line somewhere…for a weekly list of 5 great WP7 apps try http://channel9.msdn.com/Shows/Hot-Apps
