“Looking for a cheap brunch spot that your friends go to, but you haven’t tried yet? With new filtering options in Explore, you can narrow down your search results to find exactly what you’re looking for. Tap the search bar at the top of the screen, then select different options like, ‘price,’ ‘haven’t been,’ ‘saved’ or ‘open now’ to find the perfect spot,” says Foursquare.

Before today’s update, Foursquare allowed users to narrow their searches in variety of ways – by category, trending places, recently opened locations, place they haven’t been before, places friends have been, and so on. With today’s update, Foursquare is letting users narrow their searches through multiple filters.

Here’s what the new filter screen looks like. It’s accesible via a “filter” button when open up the search box.

As you can see, users can now apply different filters at the same time, including price, previous check-ins, open now, and locations that are currently offering specials. You can sort your results by best match of by distance.

Minor update? Maybe. But it’s a useful one. And it also falls in line with Foursquare’s recent push to become a true player in the local search game.

You can grab the update today over at the App Store.

Count one second. Good. In that time, 800 apps were downloaded from Apple’s App Store. That pace means that every month, Apple now sees more that 2 billion app downloads.

“Apple would like to thank our incredible customers and developers for topping 50 billion apps downloaded,” said Eddy Cue, Apple’s senior vice president of Internet Software and Services. “The App Store completely transformed how people use their mobile devices and created a thriving app ecosystem that has paid out over nine billion dollars to developers. We’re absolutely floored to cross this milestone in less than five years.”

In honor of this milestone, Apple gave away a prize for the lucky person who just happened to download number 50,000,000,000. His name is Brandon Ashmore from Mentor, Ohio, and the lucky app was Say the Same Thing, a word game that lets you and a friend bridge word gaps to find common ground. Today, he’s the proud owner of a $10,000 App Store gift card.

This isn’t the first time Apple has done this sort of promotion for a big milestone. Back in March of 2012, when Apple hit 25 billion app downloads, they gave away another $10,000 gift card to a Chinese man who downloaded the popular puzzle game Where’s My Water.

Apple says that the App Store currently boasts over 850,000 apps. They’ve come a long way from the 500 that they started out with way back in 2008.

If you were wondering, the most popular apps of all time out of those 50 billion downloaded are Angry Birds (paid) and Facebook (free).

Today, Pinterest is taking steps to make the mobile experience better with updates to their iOS and Android apps. Pinterest for iOS v 2.4 and Pinterest for Android v 1.5 are now available.

First up, Pinterest is unveiling new search suggestions inside the app.

“We’ll now suggest search terms as you type on mobile. You can also see recent searches you made from other places, so if you searched for a soup recipe from your computer, you can do the same search when you’re at the grocery store with just your phone to help you. It’s easy to delete these searches from your settings if you want to,” says Pinterest.

As you can see, searching for something like “apple” now yields suggestions for apple-related content. This also works with user search. It’s a small, but useful improvement.

The other additions to come along with today’s update are a long time coming, quite frankly. With the new versions, you can now @ mention other users. Both iOS and Android users can now get notifications as well.

“Now you can see who commented on your pin or mentioned you whenever you have your phone handy. And if you can’t get enough, we’re also introducing push notifications so you can find out what’s happening without even opening the Pinterest app,” says Pinterest.

The iOS update also brings a couple of new features, including the ability to “pin from more places more easily from the web.” This amounts to a prominent “+” button on the homescreen that lets you enter in the url of the item you wish to pin. Not quite as easy as with the desktop version of Pinterest, with that handy pin button, but it does help. iOS users can also now invite friends to group boards from the app.

All Things D reports the buy, which is for an undisclosed amount. Tunigo is a music discovery app that is available on iPhone, Android, and as a Spotify app. Tunigo is playlist-focused, and features hand-curated selections from the Tunigo team as well as ones from the Tunigo community. Playlists are arranged based on moods, events, activities, and more interesting ways.

According to the report, all of Tunigo’s 20 or so employees will become part of Spotify’s team. The Tunigo apps should keep working as usual.

“The acquisition fits into our overall strategy around music discovery, basically helping our users make sense of over 20 million tracks,” a Spotify spokesman told GigaOm.

We mentioned Twitter because the social networking site just recently unveiled their own music discovery service, Twitter Music. That product came out of the acquisition of We Are Hunted, another music discovery app. It’s interesting that Spotify would make this purchase just a couple weeks after Twitter launched their new standalone service, don’t you think?

When accessing Trends on Twitter’s “discover” tab, you’ll now see the option to get “tailored trends” or also to change location. Here’s what Twitter will tell you when you attempt to change location:

“Tailored Trends are based on your location and who you follow which make them more relevant to your interests. If you change location, you’ll see Trends based around geography only.”

You can then pick from dozens of locations – mostly larger cities across the world. if you do so, your trends will simply be based on what’s popular around you – it’ll have nothing to do with who you follow.

Updates to iOS & Android apps: See Trends from all over the world or choose to have Trends tailored to your interests.

With today’s update, replies to retweeted tweets now show both the author of the tweet and the user who retweeted it. Here’s the full list of updates to come along with version 5.6:

See what’s happening near you or around the world by viewing Trends in hundreds of locations.

Also:
• Invite friends to join Twitter from within the app
• Improved playback of Vine videos
• Replies to retweeted Tweets now include both the author and person who retweeted the Tweet
• Enjoy a smoother experience due to bug fixes and other improvements.

You can download the updates now in the App Store and on Google Play.

When shooting your Vine, all you have to do is tap a new button on the bottom-left=hand corner to toggle between using the front-facing and regular camera on your device. Naturally, this will help Vine auteurs who fancy including selfies in their videos.

Vine finally supports @mentions as well.

“Vine now supports mentions, so you can tag people in your post. Users who are mentioned will receive a notification in Activity. To mention a user, type @username and select the name among the suggestions you’ll see. See the screenshot below for an example — when I type @chris, I see suggestions for Chris Fry, Chris Hardwick and Christofer Drew. When I select Chris Hardwick, his Vine profile will automatically link in my post’s caption,” says Vine engineer Kristian Bauer.

Vine’s last iOS app update added trending hashtags to help users surface more content. Vine also recently made videos embeddable via both the web and on mobile.

Last week, Vine co-founder Dom Hofmann confirmed that Vine is coming to Android soon.

You can grab the update for Vine for iOS over at the App Store.

According to Jelly founder and CEO, Twitter co-founder Biz Stone, the company has just hired employee #1: UI designer and engineer Austin Sarner. Sarner, who got his start building Mac OS apps, worked on the Push Pop Press publishing platform that won a Apple Design Award in 2011.

Here’s Biz Stone’s welcome letter:

Jelly is thrilled to announce our official employee #1, Austin Sarner. Austin was instrumental in developing Push Pop Press, the Apple Design Award winning multi-touch user interface and publishing platform. Austin has been busy building rich software user interfaces for the past eight years.

Austin got his start creating popular shareware applications for Mac OS such as AppZapper and Disco, and spent some time working in Amsterdam with the Dutch Software company Sofa. Pushing the envelope in software design brought Austin some success in this field and helped him discover his true passion.

Clarity for Austin came in the form of understanding that software development is an effective path towards facilitating large scale positive change. Following its sale to Facebook, Austin parted ways with Push Pop Press in search of an opportunity to collaborate with like-minded individuals on something new.

We were lucky to have met Austin via a recommendation from Loren Brichter, a very highly regarded iOS developer. When someone like Loren highlights talent, we take it seriously. In Austin, Jelly has found not only a gifted engineer with an eye for interaction design, but an individual who shares our world positive philosophy.

Although this is technically employee #1, Jelly has also made some additions to the executive team. Biz Stone revealed ex-Twitter employee Ben Finkel as co-founder and Chief Technology Officer last week, and a few days later we heard that Jelly has poached Twitter Music head Kevin Thau to be the company’s COO. Although Biz Stone has yet to confirm that one.

All we really know about Jelly at this point is that it will be a mobile-focused free service of some kind.

“News of Jelly emerged unexpectedly early so I’ll wait a bit to share more about the team. In the meantime, I’ll say this. Jelly will be for everybody, it will be developed first and foremost for mobile devices, and it will be free. But, it won’t be ready for a while,” said Stone, when announcing the startup.

With this hire, it looks like they’re starting to consider what the user experience on the app will look and feel like.

Vine, Twitter’s new 6-second video app, is on the way to Android “soon.”

Speaking to The Verge, Vine Co-founder Dom Hofmann confirmed the “soon” timeframe. Nothing more, nothing less. Just “soon.” We always knew that an Android version of the popular app must be in the works, but this is the first time that we’ve heard that it is indeed on the horizon. Back in February, Vine began looking for a lead Android engineer.

He also said that a new feature is coming to the iOS version – friend tagging. But it’s currently waiting for final Apple approval.

Vine has seen quite a bit of success after its rocky start. Vine launched back in January and immediately found itself in the middle of a porn controversy. Users were shocked to find that people were using the service to post 6-second porn clips. Vine doesn’t specifically ban nudity in their terms, but they did mess up handily when they accidentally promoted an explicit video as one of their editor’s picks.

With poor user feedback and the threat of a ban in Apple’s notoriously conservative App Store, Vine made some changes to bury NSFW content deep down in the app.

But soon, we saw Vine being used in a variety of ways: for promotion and for politics. For comedy and for game teasers. Vine even played a pretty big role in raw footage from the Boston Marathon bombings.

When Vine finally comes to Android, you can expect its presence to rise significantly. It’ll probably look a lot like the moment when Instagram finally launched on Android – but this time I don’t expect iOS users to get all pissy about their favorite app opening up to the masses.

First off, Twitter for Mac now has Retina display support.

“Now Twitter is even more vibrant and detailed on the highest resolution Mac notebooks. With this update, Tweets will be clearer and sharper, creating a more vivid experience,” says Twitter.

There’s also a new share photo button in the compose box of tweets. Plus, Twitter for Mac is now available in 14 new languages: Dutch, French, German, Indonesian, Italian, Japanese, Korean, Malay, Portuguese, Russian, Simplified Chinese, Spanish, Traditional Chinese, Turkish.

Twitter for Mac Tech Lead Ben Sandofsky wrote today’s Twitter blog post on the update, and in it he says that we should “keep an eye out for more improvements to come.” Apparently, he’s serious about devoting more time to Twitter for Mac:

P.S. I’m taking a break from iOS to work on Twitter for Mac full time.

Tumblr has finally given iOS users the ability to share posts via Facebook and Twitter – something that other Tumblr users have been able to do for a while now.

For those who wish to browse Tumblr outside the official app, they’ve also added Pocket and Instapaper support to the iOS app. The new app also features a new email template which lets users easily view messages in either the Tumblr app or their mail client.

Smaller updates include scrolling animated GIFs and a new photo-disposal gesture. Here’s te full list of updates:

• Share posts via Twitter, Facebook, and more
• Save stuff for later using Instapaper and Pocket
• Email an entire post with our beautiful new template
• Fling a photo up or down to close it!
• GIFs animate while you scroll*
• Following list is now alphabetized and searchable

This update comes just a couple of days after Tumblr launched their first-ever in-feed mobile ads for both iOS and Android. Users will now see as many as four ads a day from the likes of Pepsi, GE, and Warner Bros.

And they also just launched their first-ever Window Phone app.
