Little Photo is the other photo app I use for pictures on my Android. It has a ton of filters, and the ability to layer filters or adjust the amount that they’re applied, which is a great feature. Unfortunately, it’s still a little buggy. Sometimes the filter bar is really unresponsive. It does have some of the best filters of the three we’ve talked about, and it’s free, so it’s worth downloading as long as you have a little patience with it.
