35. Paper by FiftyThree (free)
"I don't do any design work on my iPad," says web designer and product company founder Elliot Jay Stocks, but it appears that Paper has at least set him on the path. "I've recently been using it to do some rough sketches. Previously, I'd toyed around with Adobe Ideas, but Paper's friendly UI and life-like tools appeal to the illustrator in me. Even the roughest wireframes now look wonderful, thanks to the ink pen and the gorgeous watercolour brush!"
Paper by FiftyThree has recently had an update - read our review here.
Designer's pick - Elliot Jay Stocks
Paper is the choice of Elliot Jay Stocks, a Bristol-based designer, speaker and author. He's also publisher of 8 Faces, a print magazine for devotees of typography. Mire recently Stocks co-founded Viewport Industries with his friend and former colleague Keir Whitaker, and the two of them are currently working on a series of exciting projects aimed at web professionals.
36. PDF Cabinet ($2.99/£1.99)
PDF Cabinet is a fast and easy-to-use editor and organiser for the portable document format. Tap and hold a document to drag it into a folder, delete, print, or share it via email, wifi or Bluetooth. The iPad app integrates with Mail and Safari, plus you can download documents directly from a URL and photos from your photo library.
37. FormIt (free)
The software supports a Building Information Modeling (BIM) workflow in the concepual stages of a project, and uses real-world site information using the iPad's location services to support early design decisions with real building data.
FormIt supports RVT and SAT file formats, and desgns can be stored and shared in the cloud using Autodesk 360 cloud services.
38. Camera+ ($0.99/£0.69)
iPad app Camera+ essentially does three things extremely well: capture, editing and sharing, and offers some terrific extras compared to the built-in Camera app. For example, if you have a new iPad (which has a proper movable lens system, and actually takes good photos), you can split the touch points for where you want the camera to focus and for where you want it to expose. You also get the option of shooting in burst mode (though the pictures are very low-res), shooting with a five-second time delay, or shooting automatically when the iPad detects it’s being held steadily.
When editing, there's a good range of special effects you can apply, and you can stack up multiple effects - setting the intensity of each, or even brushing the effect on or off with a configurable brush tool. You can also apply Scenes, optimising the shot for modes such as Cloudy or Sunset, and the Clarity filter gives most photos an instant lift.
39. Color Thief ($1.99/£1.49)
Here's an intriguing variation on the numerous photo filter apps available for the iPad. Color Thief lets you use any photo on your device as a filter for any other. If you like how one photo feels, you can match its mood to other images - in theory, this gives you an infinite range of filters. Results are better with some shots than for others, but overall this app proves the adage that the simplest apps are the best.
40. iDraw ($8.99/£5.99)
Rather than the drawing app its name suggests, iDraw seeks to be a fully-fledged vector illustration tool similar to Adobe software such as Illustrator and InDesign. You can edit designs created in this iPad app in other vector applications by exporting them as PDF or SVG files. If you're looking to create a quick document layout, flow chart, graph or any other vector-based image, then this is well worth checking out.
41. Flipboard (free)
AKQA's founder Ajaz Ahmed is a big fan of social news reader Flipboard, primarily because it succeeded in totally reinventing newsreader apps, making your feeds more enjoyable to consume. "That's because of the rhythmic way it presents stories, rather than bombarding you," he explains. "Flipboard is great because it is not chronological but more aesthetic and has a better flow, including feeds from all the sources that are important to you."
Designer's pick - Ajaz Ahmed
Flipboard is the choice of Ajaz Ahmed, the founder and chairman of award-winning AKQA, the largest independent digital agency in the world. The company now employs more than 1000 staff across the US, Europe and Asia and AKQA is the company some of the world's biggest brands turn to when they want to embark upon innovative digital advertising campaigns.
42. HTML Cheat Sheet
A good tool for HTML beginners, you can even test code inside this iPad app. Whether you're a web design pro who needs a quick reference guide, or if you're still a beginner to HTML, this app is a great buy. Fully searchable, its easy to use interface makes it a speedy way to find what you're looking for. Written and reviewed by developers who use HTML on a daily basis, it works offline, and you can even write and test your HTML inside the app.
43. Forger ($2.99/£1.99)
This sculpting app for the iPad comes with a selection of tools that makes freeform 3D modelling possible on the go. With a selection of premade base meshes, it's fast to get started with, while saving is a doddle and you can export to your favourite desktop software once you're done. The GUI is simple but offers a wide assortment of tools that all work in a familiar way, including a set of texturing tools that let you project images onto your mesh.
44. TreeSketch 2.0 (free)
Although its commercial uses are perhaps a little limited, TreeSketch is a fantastic little iPad app that makes creating trees a doddle. You can define everything from the droopiness of branches to the size and quantity of leaves. There are numerous species to get started with and it's incredibly fun drawing out the trunk shape with a finger-tip. The results are high quality and you can save, reload and export your fully textured trees from an object manager.
45. Capture Pilot (free)
"There have been surprisingly few apps I find useful for my photography needs apart from one that is an absolute game changer" says photographer Henry Hargreaves. "Capture Pilot, which runs along side Capture One Pro, allows the iPad to mirror images that you are tethering form your camera to your computer.
"It helps to get the clients away from your computer; you can just set them up on the couch with a coffee and iPad and enjoy the freedom it brings. It also allows you to work remotely - you can trigger the shutter and work closely with your subject without having to be near your computer or camera."
Designer's pick - Henry Hargreaves
Capture Pilot was the choice of Henry Hargreaves, a New Zealand still life, art and fashion photographer working out of his studio in Brooklyn, NYC. He is known for fun, creative, provocative and memorable images, with his previosu clients including Ralph Lauren, Stefan Sagmeister, Boucheron, V and New York Magazine.
46. Diet Coda ($19.99/£13.99)
This iPad app allows you to access files on your FTP/SFTP servers and edit them pretty much as you would on a desktop. For those who use Coda on the Mac this is the perfect companion for making quick fixes to your websites on the go.
47. Silkscreen (free)
Silkscreen lets you quickly view files on your iPad or iPhone. With more people designing for mobile devices, it’s good practice to check how your design actually looks on that device. This iPad app allows you to see early on in the design process what will and won't work on the smaller screen.
48. Instapaper (free)
Throughout your working day it’s likely that you’ll come across numerous articles to read, but not enough time to read them. This is a way to save those articles and read them at a later date. While there are similar services out there, this iPad app gives you much more control over how you categorise and share these articles.
Designer's picks - Tom Brooks
Diet Coda, Silkscreen and Instapaper were the choices of Tom Brooks, a freelance web designer, based in Oxford. Since graduating from UWE and going freelance Tom has worked with numerous small businesses and individuals as well as various agency projects for companies such as Shire, POhWER and Yahoo.
49. Ignition ($129.99/£89.99)
This iPad app is just like being in front of your computer, with all functions available to use. For that reason alone this is definitely a must-have app. Not only does it allow you to access your files from any wifi hotspot, it also allows you to manage files.
The monitor activity is also a great feature if you're worried about your employees goofing off whilst you're away from the office. Using ignition from your iPad, you can access your computer's webcam remotely using Skype, photo booth or any software that displays your webcam on screen. To do this, open Skype camera settings to see what's happening in your office from anywhere around the world.
50. AirVideo ($2.99/£1.99)
AirVideo allows you to stream almost any video file from your PC/Mac to your iPad. It's no secret that there are video formats which are not supported on the iPad. The cool thing about AirVideo is that it uses live conversion to stream videos files, which you wouldn't normally play on your iPad. You don't need to wait for the entire video to be converted either - you can start watching immediately.
This is an iPad app for those of you who have a massive media collection, as movies take up a lot of space on your already shrinking storage capacity. With AirVideo you can access your entire movie collection at the touch of a button.
Designer's picks - Raam Joshi
Ignition and AirDisplay were the choices of Raam Joshi, a web designer, internet marketer and creative director. He specialises in almost all areas of the web with a keen interest in user experience and interfaces.
51. Adobe Proto ($9.99/£6.99)
There are quite a few wireframing tools available for iPad, but alongside the aforementioned iMockups, this iPad app from Adobe really stands out. What we love about it is its gestures – you can really quickly wireframe a site or app and get your idea across to someone in no time at all.
52. Adobe Collage ($9.99)
When starting a creative project of any kind, a mood board is essential to get a flavour for the look and feel before you really put anything substantial together. This iPad app enables you to bring in images from your camera or those from Creative Cloud or Google Images; a neat tool for exploring these when on the move.
Designer's picks - Rob Carney
Adobe Proto and Adobe Collage were the choices of Rob Carney, who has most recently worked as the editor of Computer Arts magazine. As a writer, he has produced features and articles for the likes of Mac Format, Tap!, Practical Photoshop and Adobe Creative Juices.
53. Adobe Photoshop Touch ($9.99/£6.99)
It may not be Photoshop CS6, and Adobe Photoshop Touch isn't without its limitations - there's no RAW import, and the maximum image export size is 1600-by-1600. However, this iPad app retains enough of its desktop cousin's features (and places them in a sleek, pared-down, tablet-optimised interface) to make it an essential purchase, and one of the best iPad apps for designers.
Video editor, graphic and web designer Nicholas Patten says he particularly likes "how it allows the user to still use layers and control opacity levels and blend modes". And the fact that it costs less than a pub lunch doesn't hurt either.
54. Adobe Ideas ($9.99/£6.99)
Suitably named, the thinking behind this iPad app is to get visual brainwaves down rapidly. The app provides a simple but effective toolset for outlines, thumbnails and rough drawings, and you can draw over the top of images (photos, screen grabs) should you wish to. Usefully, exports are vector-based and so can scale indefinitely. It's a great app for fast sketching of any ideas and designs.
