Google is just dusting the covers of Snapseed, as part of it’s acquisition of Nik Software recently and the versions for iOS and Android are completely free to use.
The program features
- Basic adjustments like crop, tuning and straightening
- “Creative Filters” aka Hipster filters like Instagram
- Auto adjustment with a twist, you can tap an important area of a picture (like the face) to automatically adjust it
- Sharing via G+ “and other services”
So, it looks like there is built in G+ sharing which is good for Google to try to get more people to use it.
