I have a couple of friends that are also into photography, we try to meet up on a regular basis and take pictures. We soon realised that we need themes, and we did not find an easy solution to the problem. So I sat down one weekend and created challenge.camera. The site has been up since mid-2019, and has seen some traffic. To make it even easier, I decided to make an app that links to the webpage, and here it is! All example images are copyrighted be me fredrikmolnar.se or from unsplash.com. If you have any suggestions, send an email to suggestions@challenge.camera Enjoy!
12px Photo Challenge
Read full descriptionHide full description
Photo challenges every month: each month a topic will be published and participants have to upload their work. Test your imagination and ability as a photographer. When uploading a participation, simply choose from the gallery or from your mobile camera. The image metadata (if any) will then be automatically populated. You just have to fill in the title of the photo and if you want us to share your work on our social networks. The idea is that you upload a photo captured the current month, so you force yourself to go out, use your camera, and capture something fresh. But of course, you can upload what you want. You can modify or delete your participation at any time, as well as modify the details of the photo: title, description, metadata... You will also be able to comment on other images participating in the different monthly photography challenges. As soon as the contest ends, 12px.app team will review all the photographs and make a selection of the best ones. To see the winners, simply navigate the app to the "Previous" section, where all past challenges will appear. In the Profile section you can see all your uploaded photos, as well as add or delete access methods to your account.

Verdict
The clearest difference is ads: challenge.camera at none against 12px Photo Challenge's shown. 12px Photo Challenge's advantage is update cadence (every 4 weeks vs every 4 months) and iOS requirement (12.0 vs 15.6). On price, in-app purchases and device support there is nothing between them.
