Capo wants you to learn your favorite songs – without resorting to tabs or sheet music. Instead, Capo analyzes any track you load into it, and automatically attempts to display its chords, tempo and key.
The app doesn’t get everything right, but provides a starting point – useful for obscure titles you can’t find tab for online. Capo’s chords are editable – you can adjust what it presents and add your own; also, songs can be viewed in various ways, including by structure, bar, and as an efficient chords grid.
During playback, the app offers further useful features: you can transpose songs to different keys, slow down the song without affecting its pitch, and create looping regions. Saving edits requires a subscription, but the basics are free to try, so you can see if Capo is your idea of a hit.
Inkwork is an app designed to instantly transform a photo into a sketch-based work of art. And, yes, we’ve seen this all before – but few filter apps catch the eye in quite the same way as Inkwork.
The interface is sleek and polished. You can quickly switch background and ink colors, and the size of the strokes, thereby making your virtual sketch more detailed or abstract, but really it’s the filters themselves you’ll spend most time fiddling with.
There are loads of them – perhaps a few too many, because the choice can initially be a bit overwhelming – but for anyone who likes black and white art, there’s everything here from scratchy pen hatching to stylized comic-book fare. Selections happen instantly and without needing the internet, cementing the app’s place in our list.
RTRO is a vintage camera app from the folks behind Pro Camera. But whereas that app’s a serious sort, attempting to transform your iPhone into a DSLR, RTRO is a mite more playful.
That doesn’t mean the app isn’t stylish, though; RTRO has a minimalist retro vibe that sits nicely alongside its various vintage looks that you apply to your movies. These range from distressed VHS fuzz to subtle color shifts and film grain. Every filter has notes from its creator, outlining what they were aiming for.
Shooting is simple, and you can capture up to 60 seconds of video across multiple shots, before sharing your miniature masterpiece with your social network of choice. Neatly, although there is a subscription charge, you can alternatively opt to buy one-off looks at a couple of bucks a pop.
Apollo enables you to apply new light sources to Portrait Mode photos. This kind of photo records depth information, and can be shot on any relatively recent iPhone (iPhone 7 Plus/8 Plus/any ‘X’ iPhone). In Apple’s Photos app, you can add studio-style lighting, but Apollo takes things further.
The interface is usable, and offers scope for creativity. It’s simple to add multiple lights, and then for each one defines distance, color, brightness, spread, and mask effects for simulating effects such as shadows being cast from light coming through a window blind.
Apollo perhaps isn’t an iPhone app if you want an instant fix. It demands you delve into the details, and fine-tune your settings. Also, it doesn’t always create a realistic result. But when it works, this is a little slice of magic, enabling you to apply complex lighting to a photo after the fact.
TouchRetouch can rid photos of unwanted elements. Such tools are commonplace – even in free apps like Snapseed – but TouchRetouch being dedicated to the task affords it focus; more importantly, the tools you get are really good.
Blemishes on faces can be removed with a tap. Larger objects can be painted out, whereupon the app fills in the gaps. Alternatively, you can clone from one part of the image to another. There’s also a line remover, which smartly makes short work of power lines and the like that otherwise carve their way across your pic.
Obviously, automation of this kind has some shortcomings – TouchRetouch can’t match desktop apps where you partake in painstaking, time-consuming, pro-level retouching. But for the average iPhone owner wanting to remove annoying things from pics, it’s well worth the small outlay.
