Square UI Free – User Interface Kit


Square UI is our latest PSD User Interface Pack including a set of beautiful and pure components, which you can use to create startup projects, websites or iOS apps. Square UI Kit for designers featuring the flat design trend.

We love the latest flat design trend, and Square UI is made exactly in that style. The simple, colorful and flat-designed components of Square UI are perfect for almost any project, from complex web applications and small startup projects to websites.

The best part? We are offering Video players, Buttons, Text Edits, Menu items and other awesome pieces ABSOLUTELY FREE! For your convenience, we have come up with a color scheme, and have separated it in styles (.asl) and color swatches (.aco).

All components are made in Shape Layers, so Square UI Free is ready for Retina Display. Text elements use the Montserrat typeface, and this great font available free from Google Web Fonts. We used works of the wonderful illustrator Anna Kulakovskaja for Square UI as well.

We create many free UI Kits, and with every new release they become more beautiful and with expanded features.

We hope you will enjoy this new product, and if you use it, do not forget to share your projects with us. We love to see all the great things you are working on!

    FYI – The twitter share link in the chrome browser (mac os x) does not function correctly and does not redirect you back to the site displaying the download link. Works fine on firefox.

  9. Damián Feb 18, 10:19 pm

    Awesome UI. The flat design seems to be a trend. I personally love it.

  10. Anas Feb 18, 11:07 pm

    Great work, well done.
    Can I use this work to make an android flat template and use it for commercial?

    • Adrian Feb 18, 11:09 pm

      Yes you can. We’ll highly appreciate if you mention us in your documentation, but is not mandatory :)

  11. Neil Rieger Feb 18, 11:55 pm

  15. Murray Chapman Feb 19, 2:18 pm

    Am I missing something? Where is the link to make a tweet???

    • Adrian Feb 19, 2:26 pm

      Check the Blue box from article.

      • Murray Chapman Feb 19, 4:44 pm

        Hi Adrian.
        Thanks for that. Something was blocking the button from showing so all I saw was a white box. I tried in another browser and luckily the tweet button was there.

  16. damien Feb 19, 3:49 pm

    Same here, I tweeted but did not get the link :s

  17. Michael Feb 19, 7:15 pm

    Just a small piece of advice. In order to download, turn off DoNotTrackMe plugin if you are using it.

  18. Jack NUMBER Feb 19, 7:21 pm

    The Tweet button down on Chrome (lasted) :/
    Many thanks for the kit !

  19. Joseph Mainwaring Feb 19, 8:24 pm

    Thanks for sharing, I was looking for a UI design like this earlier this month!

  20. Susan Feb 21, 1:01 am

    I did tweet about it – but didn`t get the link.
    Could you help me?

    See my tweet here https://twitter.com/37designstories

  21. Susan Dam Feb 21, 1:10 am

    Found it and its super nice. Sorry :-)

  22. Kas Ude Feb 21, 5:22 am

    With “Flat design” the new thing in app design, you would think that Illustrator would beat out Photoshop as the preferred weapon of choice given its strength in typography, layout, vectors, etc etc. Any chance you would be able to offer the same kits (perhaps as paid) in illustrator format?

  23. mojo706 Feb 21, 12:24 pm

    Great design just what I need for my next project! I am going to try using the kit to make a unified experience from Desktop to Mobile. Thanks again!

  24. Marcus Feb 21, 5:21 pm

    Oh sorry. It works. I had to deactivate the DoNotTrackMe-Plugin.

  25. Francisco Feb 22, 8:13 am

    Yuck. I’m sorry, but I really dislike this new flat fad. Tried it on a few clients already and they poo poo it every time.

    • Ady Ngom Feb 23, 10:53 am

      Can you offer a better alternative, a better design that we all going to praise or are you just going pollute this thread with your useless comments.

  26. Ady Ngom Feb 22, 8:52 pm

    Thank you soooooo much Adrian and team, I have a grid theme that really needed some design love and this is just perfect. By the way putting freely available fonts made a huge difference as soon as I applied Montserrat and Open Sans the design started to pop and that is a huge time saver. I know the pro version is out I will buy it to support it and hopefully some day “The Bricks” will have free fonts references as well (shameless plea) :)
    I will post the before and after of what I’m working on soon.

  27. Mohammed Ameen Feb 23, 7:12 pm

    Wonderful. I’ve built similar elements for my own projects but this seems interesting. Also, what is the difference between this and the Premium version?

  28. Armin Feb 24, 5:32 am

    Hi Guys, great work.

    When I try to install the “Swatches.aco” PS says: “Could not complete your request because an unexpected end-of-file was encountered.”. Any suggestions?


  29. ossama Feb 25, 11:26 am

    Did i have the rights to convert this psd to HTML/CSS and sell the codes?

  30. Tom Mar 5, 10:11 pm

    Hello, great job, so nice !
    I don’t have tweeter acompte…
    Have you another way to download this UI kit ?


  31. Offa Mar 8, 8:14 pm

    Sorry, this is stupid. The twitter thingy is not working. We all know this is a demo version of your product. You should call it demo or lite and make a comparison with a download link. Marketing bs…

    • Adrian Mar 8, 8:32 pm

      Is not a demo, is free version of functional product, but shorted version.

  32. Mike Deitrick Mar 12, 8:59 pm

    Back on February 18th a user commented on the fact that they did not have a twitter account, and therefore could not download the kit. You stated that the requirement to tweet for download would be removed in a couple of days. Is this still going to hold true?

  33. V Hale Mar 28, 8:18 am

    What can we use this free version for? Anything?

    • Adrian Mar 28, 10:41 am

      Please download the pack and reading license. You are free to use it for any project.

  34. gallap Mar 29, 3:58 am

    thanks .
    Great work, well done.

  35. nappzman Apr 22, 7:41 am

    Looks really cool – can’t wait to try it out!!

  36. Julia Apr 26, 11:04 am

    Hi Adrain,
    This is really amazing.
    Since I am a newbie to web designing I would really appreciate if you could provide tutorials on how to code Square UI.


  37. Maxim Sokhatsky May 23, 12:15 pm

    Hello, guys!

    Is there any chance to get Square UI in LESS or SASS variant like Flat UI Pro ?

    • Adrian May 23, 12:32 pm

      We will announce about this, now we working on Flat UI updates and new UI Kit.

  38. Prakash May 26, 10:05 pm

  39. Stefan Jun 17, 11:14 am
