iOS Apps on Sale for 15 March: Sunrizer, Fractals & Kingdom Rush

Tim Brookes 15-03-2014

Sales are brief in the mobile world – sometimes they last only a few hours, others can last days and the App of the Week (which if it happens to be a paid app is offered up free of charge) gets seven whole days.


Unlike cheap hardware, cheap apps are often quite the bargain – but you’d better be quick. This week’s deals are light on games and heavy on entertainment and utilities, with a fractal generator, virtual analog synthesizer and yet another of Brian Cox’s science apps going cheap.


Sunrizer ($9.99, $2.99)

I bought Sunrizer while at its full price of $9.99, and I’ve never regretted spending the money on it. For $2.99, this is an absolute steal and remains one of the finest and most feature-packed synthesizers on the app store. For $3 you’ll get a virtual analog synth featuring hundreds of presets, full MIDI support (with MIDI Learn and Core MIDI support), an arpeggiator and some wonderful waveforms.

Frax / Frax HD ($1.99/$3.99, now $1.99)

Frax might be the most beautiful app on the App Store, just check out the video above if you don’t believe me. The app is a marriage of maths and art in the form of fractal geometry, but we’re moving beyond mandelbrot here. The app allows you to manipulate and design your own style of fractals using gradients, textures, light sources and gestures to change and animate the scene. Both iPhone and iPad editions are currently on sale, priced separately.

Cyclemeter GPS ($4.99, now free)

Cyclemeter is a GPS tracking app for active types. The app can track running as well as cycling, both road biking and the mountain variety. Displayed in front of the rider is a realtime panel of timing, statistics, metrics from sensors (including the M7) as well as all of your past rides and data – which also happens to sync to iCloud, across devices. This is a very complete app for cyclists, and it’s currently completely free.


Brian Cox’s Wonders of Life ($5.99, now $1.99)

BBC presenter, scientist and musician Brian Cox always seems to have an app on sale, and this week it’s Wonders of Life which takes a look at the “majesty of nature” (rather than the depths of the cosmos) in excruciating detail. The app features more than 30 fully-3D creatures and habitats to explore, over a thousand high resolution images and 2 hours of HD video.

Knock ($3.99, now $0.99)

Knock is a nifty little app that claims to let you unlock your Mac with a few taps on your iPhone. Not all Mac computers are compatible, so you’ll have to check to make sure yours is listed before purchasing. Developers claim it’s both faster and safer than typing in your password, and though I’m not so sure about that myself, at only $0.99 it’s a pretty cheap entrance fee to find out.


Kingdom Rush Frontiers ($2.99, now $0.99)

I’m not particularly fond of tower defence games but even I know that the Kingdom Rush series is widely regarded as one of (if not the) best attempts at the genre. Frontiers is the latest instalment in Ironhide’s massively successful premium tower defence franchise, offering 18 towers of varying abilities to build, more than 40 enemies to crush and 70 achievements to unlock – all for a dollar.


That’s all of this week’s best offers, be quick and be sure to check back next weekend for the best iOS Apps on Sale.
