Drawing a mobile App UI with hand-drawn methods, you would first draw a frame and it's better to even include the outline of an iPhone. This way, the rough sketch would be more enjoyable. But now, you don't have to trouble yourself with drawing the phone frame, as this website provides you with rough paper for both mobile phones and browsers. You can print it out directly and make the rough sketch, greatly enhancing the overall design experience.

Goo.gl

Google's short URL service, which offers a solution for those times when you need to use long, cumbersome URLs. With this tool, you can easily shorten a URL, no registration required, but you will need to enter a verification code every time you shorten a URL, or log in to your Gmail account to skip the verification code. Additionally, adding a "+" symbol after the shortened URL will show you the number of clicks on that link.

The service is no longer available as of 2020.1224.

 

Dropjar

This is a file upload space without registration, where you feel the most comfortable. The most attractive part is that the background of the website is a collage of illustrations or photography works, which is also a form of advertisement. The design is visually appealing, and the website is ignited with a passion for design. I think the Chinese name of this website should be "File Bottle", because the upload interface is shaped like a bottle. You can upload a file up to 10 GB, and if it exceeds 7 days, the file will disappear just like a bottle lost in the sea, avoiding the risk of file leakage. The link to the author's website is located in the bottom right corner of each work. Due to the high-quality advertising materials provided by illustrators or photographers, the website has no design, but still looks pleasing to the eye. Among all the free spaces, Dropjar is more attractive to users because it always has unexpected and beautiful pictures.

2020.1224 Update: Seems to have ended service QAQ

 

Colour lovers

A good website for color scheme combinations, "Flatuicolors" not only has a color tool but also features a community aspect. You can follow specific people's color styles, discuss color schemes with others, or even challenge others to create a color scheme. The site also combines different graphics for different color combinations. This website is perfect for finding color friends. (It's a bit weird somewhere~)
