@toby, I think you kind of said it... It doesn't get regular updates because we're not developing it in-house. This is an open source initiative from our community. Here is the repository on GitHub - looks quiet for almost a year now.
So the main disadvantage would perhaps be that if you have issues with capturing and uploading photos then there is no immediate support compared to the Android and iOS apps. Have you tried, how is it working for you right now?
