We’ve long had a bit of a soft spot for Snapseed. Its intuitive interface was always one of the most tactile on Android; moreover, the huge range of filters and effects made it perfect for all manner of photographic manipulation and fine-tuning. But with 2015’s major revamp, Snapseed became further entrenched in must-have territory.
The star of the upgrade: Stacks, which converts each filter you apply into an editable layer. This means each effect can later be tweaked, rather than being burned into your image when applied, thereby providing even more scope for experimentation. Handily, stacks can also be saved for later re-use.
