• = Free stuff.

Aside of “default designer package” for my workflow, here are some of apps that I use:

1. GetCloud App — http://getcloudapp.com For sharing screenshots and files

2. ClipMenu — http://www.clipmenu.com/ Essentially it's an app for managing clipboard history, but I use it for snippets of placeholder text paragprahs. I'm not fan of the original lorem ipsum because it's not look like a real text, so I use excerpts from random wikipedia articles: http://c.kam88.com/NINU

3. Icon Slate — https://itunes.apple.com/us/app/icon-slate/id439697913?mt=12 For testing app icon designs. It has nifty feature of showing PNG file as icon in dock. And of course it also generates *.icns file.

4. iDocuments — http://www.icyblaze.com/idocument/ All guidelines, brand books, PDF presentations and books, just about everything that could be useful for me in future I prefer to store in iDocuments.

5. Screeny — http://www.screenyapp.com/ Sometimes it's hard to show something just by screenshots, especially if we talking about interactions with app, so for such cases I use Screeny for recording small videos

6. PopChar — http://www.macupdate.com/app/mac/7813/popchar-x For showing all character glyphs of desired font. I know that there more beautiful app called Character: https://itunes.apple.com/ru/app/characters/id536511979?mt=12 Maybe I should try and switch to it.

/* Also I'm looking for nice app for taking notes. With cross-device cloud syncing, tags and folders (markdown support will be a plus). Something between nvALT (too simple — no folders) and Evernote (too complex). If someone knows a nice app, please tell me */

Already a lot of great software mentioned, so I'll supplement a few

Alfred – http://www.alfredapp.com/ Don't put it off as "just another application launcher". It DOES launch apps, and that rather quickly and elegantly. But that's also what Spotlight and Quicksilver (free, but afaik out of active development) do really well. Alfred's strength lie in it's versatility. Need a Text Expander? Can do! Want a Multi-Clipboard? Yep, got you covered! Also, if you know just the slightest bit of AppleScript, you can create really powerful shortcuts tailored to your specific workflow. Alfred is super versatile and worth a second look.

Fantastical – http://flexibits.com/fantastical Intuitive Calendar. (Of course, you can also create new entries from within Alfred...)

Sublime Edit 2 – http://www.sublimetext.com/ Super lightweight and versatile Text Editor. In my spare time I've been doodling around in Processing, but have found the IDE a bit lacking (no code completion, no snippets, no multiple carets). Sublime offers all that, and more. No matter if you use HTML, CSS/SASS, JavaScript, Rails, Java/Processing, Python or whatnot – Sublime has got you covered.

f.lux – http://stereopsis.com/flux/ Adapts the color of your monitor to the time of day. Less strain for your eyes. (Obviously, if you need color fidelity, this isn't for you)

A few color pickers have been posted already, but I switched to Frank DeLoupe ( http://jumpzero.com/frank/ ) recently, and have not been happier. Simple and straight forward, great "loupe" overlay, nice history and color modes, and can jump right into photoshop or to the clipboard. The color preview in the eyedropper on the menu bar is the perfect little touch too.

Total Terminal to quickly access terminal tabs

I couldn't work without any of these:

• ColorSnapper, to quickly capture colours on any window.
• Jing, to quickly share screenshots.
• InvisionApp.com, to create interactive prototypes and manage feedback with my clients.
• Basecamp, to manage files and threads.
• HarvestApp.com, for online invoicing.
• BrowserStack.com, web-based browser testing.
• Silkscreen, live preview of Photoshop designs on iPhone/iPad

And others which are really indispensable in my everyday workflow (but not so much design-centric) like Evernote, Omnifocus, 1Password.
