simple app, you should have this stuff memorized anyway, this is a good memory jogger for astrophotographers of a certain age, though. Double-checked the math for 1.5x 1.6x and ff, seems good. Thanks!

Wrong calculation If you have crop sensor

It works but I'm no photographer so I have no clue how to use it.

it's still in development, but easy interface, and good interface. gets me in the ballpark of where my exposure time needs to be and that's exactly what I wanted. some customizability (some variation on zoom lens, focal length, camera type) - even if your camera isn't listed, a similar camera can get you into the right setting. looking forward to seeing what version 0.9 and 1.0 might bring. :-) (lost 1 star) for lack of a general "4/3" camera option. would also like to see 6x6 film option as well. (I shoot 4/3, several 6x6 film, and canon 70d) yes, I could do the math myself, but apps make things easier. others might appreciate an actual 35mm setting, although this can be achieved by selecting 'full frame' option. (workarounds vs simple selections) thanks! :-)

The app looks interesting, but has a number of problems. The only directions are what is found in the Google Play Store description. The author's assumptions are not explained nor what the calculations really are. The UI is simple, but it appears not to automatically correct for the crop factor. The UI also does not let you a keep a list of lenses that you commonly use for astrophotography. So it isn't as useful as it could be.
