Great summary of visual data from SDO. It even has the AIA 4500 which is no longer displayed on the official website of the mission because of the pinhole damage. That is good, I would not remove it. There is one small error in the Solar wind part - it should be km/s (kilometres per second), not Km/s (kelvinmetres per second). For future development, I suggest including latest videos for each band, which are available on SDO website.

While good, it's missing a couple features it *should* have: OK, you can use an image to set your device's wallpaper, but why it has to be BOTH wallpaper AND lockscreen?? Why can't we decide to have 1, OR other, be current Sun, & other being our favorite place on Earth?? -- Why can't it sleep 6h and auto-update that wallpaper or lockscreen, in background? -- why so many confirmations for wallpaper? -- Why can't it add sides, so we see WHOLE Sun, instead of Android's auto-trim'd version?

Thanks for your review! The wallpaper functionality is basic and the reason is that the app can be used with the Muzei Live Wallpaper app to obtain periodic update and ability to choose where to apply the wallpaper. About the confirmations, that is required by Android security requirements.
