I am a lover of subtle filters. This describes likely filters perfectly. The small changes they can bring are just enough to cause a photo to pop. I also love the fact that likely supports extensions, which means I can work in a non-destructive mode on my photos. This single feature alone started me playing with likely over another similar filter application. Now, for what I dont like. While working in the likely app preserves all your photo metadata,if I use the extensions under IOS Photos, it masks the image metadata and I lose all the information. This isnt acceptable. The other aspect that could stand improvement would be the addition to toggle on any filter back to the base image to see the effect of that specific filter. When you are scrolling through multiple filters, you tend to forget what the base image looked like, so it is hard to gain perspective on the effect of any one particular filter. Other than those things, its a quality app.
