Called ON/OFF Photo, the app essentially allows for images to be sent via instant messaging and then removed at a later date and time. Sharing images is a case of using the app to select the image you want to send, then sharing that image via the Share Sheet. Choosing stock Messages app, for example, allows images to be sent via iMessage just as many people with iPhones normally would. The difference here is that users can then select the same image in the ON/OFF Photo app and either delete it or simply turn it off.
As can be seen by watching the video embedded below, recipients view the images via a web browser, which explains how the app is capable of turning them off. When the image is shared initially, our guess is that it is uploaded to the developer’s server and a URL is shared with the recipient. When a user decides to remove access to the image in question, that’s all handled by the web server and the URL no longer produces the image. Think of it as sharing an image via a Dropbox public URL and then deleting the image later.
This, of course, all works on the provison that you are happy to send your images to the developer’s server, and depending on what those images are, you might not want to do that. It’s also debatable whether the recipient could simply save the image from within Safari should they want to, negating the whole point of the app entirely.
If you lost data after you updated to a new iPhone, you can always use Gihosoft iPhone Data Recovery to get the data back from the old iPhone or backup.You may also like: iphonerecovery.com
Still, ON/OFF Photo is free, so if you want to give it a try, you can without any monetary commitment. We’re just not sure we’d be sharing anything too risqué with it.
