December (and 2013) will soon be a distant memory, so we thought we’d take a retrospective look at some of the more notable apps to hit our radar over the past month. So without further ado, here’s a quick snapshot of some of the best iOS apps to launch in recent weeks.

Codecademy

If you want to build an app, you’ll need to learn how to code, right? The Hour of Code app by Codecademy targets total newcomers with the basics of programming.

Its relatively short repertoire covers the absolute basics, such as how programs are written and a few examples of what can be achieved with just a few lines of code.

Grand Theft Auto: San Andreas

There was good news for Grand Theft Auto fans in December – Grand Theft Auto: San Andreas went mobile, hitting iOS earlier this month.

Angry Birds Go

Rovio launched its Mario Kart-style Angry Birds racing game in December, hitting Android, Windows Phone, iOS, AND BlackBerry at the same time.

The Angry Birds franchise is growing arms (wings?) and legs now, and based on our dabblings, it has another hit on its hands.

Heyday automatically journals your photos and locations so you don’t have to.

While the setup is perhaps a little reminiscent of Rove, Heyday takes things a step further. Once you grant access, the app groups your photos, videos and locations together by day, images are displayed in grid layouts and you can even have the app automatically apply filters.

Manga Box

Japanese mobile games giant DeNA moved into manga this month, as it strives to make its mark in another entertainment vertical.

Slice [US only]

US-based consumers have perhaps encountered Slice before, a service that tracks all your online purchases and pulls the information together into one place. Thus far, Slice has been available for iPhone, Android, and the Web, but from this month, it’s available for iPad too.

Tydlig

Tydlig is a funky take on what a calculator perhaps should look like on smartphones.

Tydlig is a beautifully designed app that brings a rich array of features to the table. It lets you return to, highlight and edit any number in your sequence – when you change that number, the result updates automatically. Also, with a result selected, you can hit any operation – e.g. divide, subtract or add -  and create a linked number beneath it, which lets you kick-off a new sum related to the original one.

Yahoo Weather

Eight months after it rolled out an all-new Weather app for iPhone, Yahoo finally optimized it for iPads this month.

It taps Flickr (owned by Yahoo) to bring beautiful, relevant images to its local weather forecasts. Users can also submit their own weather-related snaps to the Project Weather Group and see their handiwork appear in-app next time it’s raining in their locale.

Journeys of Invention for iPad features 81 objects from the museum’s collection, with 14 themed interactive journeys guiding users through the exhibits. It includes Scott’s Antarctic Medical Chest, an Apple I computer, the Apollo 10 Command Module, a Cray supercomputer, Enigma and a 3D-printed gun.

Unfortunately, only one of the journeys is completely free, though a second one (‘New Science’) can be unlocked if you connect your Facebook account or sign-up by email. The remaining 12 require an in-app purchase of $9.99 (£6.99).

Cut the Rope 2

As expected, ZeptoLab released the follow-up to its uber-popular puzzler Cut the Rope this month.

In Cut the Rope 2, players are still tasked with collecting candy for Om Nom, although this time he’s joined by a cast of supporting characters called Toss, Boo and Blue.

The app showcases a different non-profit organization each day, and provides a payment facility for users to donate $1 to the cause. Details of organizations can be shared with friends from inside the app, and there’s an option to match friends’ donations too.

Flow for Instagram

While Instagram has yet to launch an iPad-optimized app, there continues to be a steady stream of third-party clients waiting to fill this void. The latest one is Flow, and it’s pretty sweet.

Feature-wise, there’s nothing revolutionary in there, but it’s all about the browsing experience – Flow does exactly what its name suggests and is slick and fast.

The more you use it, the more you notice the little navigational nuances, such as long-pressing an image to bring up details of the user-profile behind the shared-image. And tapping on an image once to start a gallery-style display that lets you swipe through everything in your feed.
