It's time for our weekly roundup of the best new iPhone and iPad apps and games to have emerged on Apple's App Store.

As ever, prices are correct at the time of writing, but may have changed by the time you read this. (Free + IAP) means in-app purchases are used within the app.

APPS

Cinamatic (£1.49 + IAP)

Photo-sharing app Hipstamatic remains a going concern: it's not Instagram-big but it has a passionate community of snappers sharing their images. Now it has a new app focusing on shortform video: 3-15-second clips that can be shared to Instagram, Vine and Facebook, with an array of filter effects that can be applied first.
iPhone

Adobe Voice (Free + IAP)

This is a curveball from Adobe: an app to "tell your story" through the medium of animated videos. What that means is choosing from more than 25,000 images (or adding your own) and turning them into an animated slideshow with you talking over the top. It's a business tool, really, but one that could have wide applications.
iPad

Yahoo Sport (Free)

This app's new to the UK: Yahoo's sports-tracking app offering news, scores and stats from a host of sports and leagues, including football (both varieties), tennis, golf and pretty much every US league you can think of. Features include event alerts to keep you posted on specific games, and personalisation to set your favourite teams in the various competitions.
iPhone / iPad

Curious Ruler (Free)

If your children are learning about measurements and comparisons at school, Curious Ruler could be the perfect way to practise the concepts at home. It gets kids to choose a reference object from 36 – coins, crayons and Lego bricks through to footballs and iPads – then place another object they want to measure next to it, and point the device's camera at them. On-screen sliders then compare the objects. Inventive and interesting.
iPhone / iPad

Nito (Free + IAP)

Nito looks like a novelty app, but it's a fun one. It gets you to stare into the screen and speak, while making whatever facial expressions you like – then maps all that to 3D avatars including animals, monsters and human characters. The idea being that you then send the resulting video messages to friends.
iPhone / iPad

Transformers: Age of Extinction Movie: Official App (Free)

With a new Transformers film on the way, there's an official app from Hasbro. It's mainly promotional: trailers, interviews, character biographies and so on – oh yes, and obviously the toys – but there's also a gaming element. Weekly "missions" will play out over the coming weeks, as fans earn points for staying engaged.
iPhone / iPad

Voice - Give and gather opinions (Free)

There have been quite a few "Ask your friends / the world for opinions and get them back on your smartphone" apps, and few have really taken off. Can Voice buck the trend? You can ask questions and browse those of other people, with a follow model used to keep tabs on people you find interesting. Fun for impromptu polls, but much depends on whether it can get a big bunch of people using it for the long term.
iPhone

Mimi Hearing Test (Free)

The science of hearing is fascinating: I once had a hearing test and they could tell in a few seconds that I'd been to a few too many gigs, based on the frequency I was missing. Mimi Hearing Test is an app based on that science which helps you understand where your hearing is lacking (if it is), while also teaching you about different types of hearing loss by simulating them.
iPhone

Dr Panda’s Toy Cars (£1.49)

The Dr Panda series of children's apps has been getting increasingly ambitious, with Dr Panda's Toy Cars the latest sign of developer TribePlay's desire to become a brand as familiar to parents as Toca Boca. The idea here is that kids get to drive eight vehicles around a cartoon town, including police cars and cargo trucks. It's a mixture of exploration and play, with each vehicle having its own interactive aspects for children to roleplay.
iPhone / iPad

Time.is (£1.49)

The Time.is website is very handy: showing accurate times for whatever time zone / city you like. Now there's an iPad app, showing times in a choice of digits or words, synchronised to atomic clock time. There's a list of popular cities for fast access, but a much wider database to tap into. Ideal to have at hand if you're regularly coordinating across time zones.
iPad

GAMES

Kiwanuka (£1.49)

In an increasingly-long line of delightful puzzle games on iOS, Kiwanuka is one of the best. It sees you guiding a colourful collection of characters to freedom using a glowing staff: like a neon-infused Lemmings built for touchscreens. File alongside Monument Valley in this year's games-worth-paying-for pile.
iPhone / iPad

Botanicula (£2.99)

Oh, and here's another one: an adventure game from developer Amanita Design, who made the equally-excellent Machinarium. Converted from a critically-acclaimed PC game, it sees you controlling five "little tree creatures" as they explore a beautifully-realised world of seeds and parasites. A joy to explore at your leisure.
iPad

Record Run (Free + IAP)

Another endless runner: a genre that's nearly as packed on iOS as the start of the London Marathon. This one at least comes from an interesting source though: music game maker Harmonix, of Rock Band and Dance Central fame. Their twist on the "run, jump, slide and dodge" genre is musical: it uses the songs stored on your device to fuel its levels. Fun, although if you've switched to a streaming service like Spotify or Deezer, you'll need to remember how to sideload your collection.
iPhone / iPad

Frederic - Evil Strikes Back (£2.49)

More music here: as far as I can tell, developer Forever Entertainment's Frederic – Resurrection of Music was the first mobile game based on composer Frederic Chopin. That presumably makes this sequel the second: "music duels" based on his works, with a story wrapped around it about "soulless artists with their same-sounding radio hits". Quirky but good fun.
iPhone / iPad

QuizTix: Pop Music (Free + IAP)

Trivia games are increasingly-big business on mobile, as the rapid rise to fame of QuizUp has shown. Developer QuizTix is hoping to get in on the question-answering action with its own series of social trivia titles, with its Pop Music game offering plenty of questions, daily challenges and Facebook and Twitter-fuelled social features. And if the app appeals but its topic doesn't, try QuizTix: Movies instead.
iPhone / iPad

MLB Perfect Inning (Free + IAP)

Cricket has proved a problematic genre for game developers on all platforms, but baseball has been far more favourable. Gamevil's new game is the latest polished take on American rounders, with an official licence and very slick graphics in its favour. There's a comprehensive choice of modes and gameplay options too: plenty of depth, although obviously it's best if you're starting with some knowledge of baseball.
iPhone / iPad

Warhammer 40,000: Carnage (£4.99 + IAP)

If the recent Plants vs. Zombies-alike Warhammer 40,000: Storm of Vengeance wasn't to your liking, how about this? It's more the action game that fans of Games Workshop's famous tabletop game might have been hoping for, as you suit up as a space marine and head off to shoot the bejaysus out of hosts of enemies, upgrading your weaponry along the way. Frantically good, whether you're a 40K veteran or new to the world.
iPhone / iPad

CastleStorm - Free to Siege (Free + IAP)

CastleStorm has enough to make it stand out from the crowd of mobile tower defence games. Not least because you're on the attack – trying to destroy your opponent's castle – as well as defending your own. All this is handled with a well-worked system of buying and upgrading weapons and units, with four campaigns to work your way through, and in-app purchases that aren't too aggressively pushed at you.
iPhone / iPad

Dark Lands (£1.99 + IAP)

More running – the lines between endless runner and platform game are blurry nowadays – with a fantasy/horror theme and atmospheric visuals. There's a choice of the 40-mission adventure mode (platform game) and the endless mode (endless runner), with the graphics and sound combining to give the familiar themes a kick.
iPhone / iPad

Dragon Coins (Free + IAP)

Finally, something strange from Japan in the form of Sega's Dragon Coins, based – no, really – on those coin-dropping machines you find in arcades around the world. Here, you're not just hoping to win a few 2ps: you're charging up monsters for battle, collecting and fusing new beasties to give yourself a better chance. And yes, the in-app purchases ARE used to buy more coins.
