We've just posted a public beta of SkyDemon 3.5 on our Android page, which includes rainfall imagery. Please give it a try and let us know here how you get on.

Worked fine, rain disappears when you Zoom in, that's OK. I wondered if it would be better to show the 2/3 last rain pictures to give an idea of track. I wouldn't want to use it while flying. Personally happy to use raintoday for this as part of my weather planning, but useful as a final check without opening another window. Does it store the rain picture so it can display last one received when offline?
[Edit] yes it does, and displays what time received [/edit]
[Edit2]oh slider, thanks!, missed that[Edit2]
[Edit3]Slider is great!, and it does a bit of the future . I take it back, this is WAY better than raintoday. The weather tab does take a lot of real estate when animating tho' (sshot). The ability to run the animation was terrific, I wonder if it could be set to run 3/5 times and to close the weather tab while it does it (would need a time display)[/Edit3]

Didn't work, displayed pink overlay: fair enough screenshot available

I've also intermittently had the pink overlay issue - closing SD and reopening it seemed to clear it for me.
