Adobe will pull Photoshop Touch from Google Play on May 28. The company believes that their new mobile apps will better meet the needs of their customers going forward. While these tools are currently only available on iOS, Adobe announced that they are currently developing new apps for Android, which they will debut soon. For current users of Photoshop Touch on Android, Adobe says the app will continue to function on their devices, but will receive no future support:
Sometimes building for the future means we need to make hard choices and today I am also announcing that we are discontinuing Photoshop Touch. For those of you who have been using Photoshop Touch, thank you and please continue creating amazing work with it; while it will no longer be available in stores as of May 28th and we won't ship further updates, it will remain completely functional on your devices for the foreseeable future.
There is no word yet on whether or not Adobe will also discontinue Photoshop Express for Android as well.
