Unsplash is a website specialising in free to use, user submitted, photos of high quality. There are a couple of good iPad apps to find and download photos.
If you are a member of Unsplash and want to log in when you use it, UrWall is a good choice.
If you do not want to log in Splasher is another good choice.
Both of these apps contain ads. I haven’t found a way to pay to get rid of them.
Here is an excerpt of the Unsplash license terms:
More precisely, Unsplash grants you an irrevocable, nonexclusive copyright license to download, copy, modify, distribute, perform, and use photos from Unsplash for free, including for commercial purposes, without permission from or attributing the photographer or Unsplash. This license does not include the right to compile photos from Unsplash to replicate a similar or competing service.
Have you found another, perhaps better, Unsplash app? Or one where you can pay to get rid of ads? Comment below.
