Is there an equivalent to Halide or Spectre (for raw still photos/long-exposure photos) for Android? My Thinkphone has a pretty awesome camera and native camera app with integrated RAW output, but these apps do often provide some features and polish beyond what's available in that tool. For example, I was just trying to take a long-exposure photo of the aurora (visible a couple weeks ago here in Michgan) and the limits on even the manual controls had ranges that limited what I could do. Spectre (or its equivalent) would have been awesome to have.
