Flashes, a photo-sharing app thats linked to X-alternative Bluesky, launched in beta this week before disappearing from the test store due to what its developer said was technical difficulties.Flashes developer Sebastian Vogelsang said in a Bluesky post that Apples engineering team is working on a fix. Apple didnt immediately respond to Fast Companys request for comment.Flashes, which was revealed last month, supports photo posts of up to four images and videos up to one minute long. Items posted on Flashes will also appear on Bluesky. Comments from Bluesky users on the posts will appear back on Flashes. Flashes could be attractive to users who want to veer away from Metas social media ecosystem and other Big Tech platforms. A way to do that, many believe, is through open social media ecosystems. That way no one person is mean to control it. Bluesky, which is built on the open source AT Protocol, took off as more and more people seemed to become dismayed withMusks shift to the political right. Bluesky has amassed nearly 31 million users so far. Thousands of curious testers flocked to try out the Instagram alternative by Vogelsang. TechCrunch reported that 3,500 users signed up for Flashes within its first hour before it closed off.
