Photoshop Touch recreates much of the core tools found in the desktop version of Photoshop, but falls short of being as powerful. Adobe is instead fleshing out their Creative Cloud apps like Shape CC, Color CC, Brush CC, Comp CC and Photoshop Mix.
A subscription service is offered for users who want to tap into Adobe’s Creative Cloud, which syncs edits to a cloud server for easier use between apps or from mobile to desktop (and vice versa). The apps are free to download; Adobe only charges if you choose to tap into its cloud storage option.
Photoshop Touch will be available for download until May 28. Adobe will no longer support the app after that date, but it will continue to work on your devices.
