1. Lots of possibilities for more effects in the future, but it has a decent selection right now (you should really buy this, otherwise all you get is rain and sun (day/night.)) Effects are cumulative (e.g. Daytime+Clouds+Rain all at once.) One problem is, you cannot SEE the effects from inside the app unless the temperature outside matches the effect, so you /might/ think they do not work; try the random setting instead.
2. once you do though it's an amazing app that ads the current weather effects (or random ones if your a spaz) overlaid onto your wall paper.
3. Many years ago, I had an LG G4 with magnificent animated weather effects built in its stock software.
4. I installed it trying to put weather effects on my lock screen.
5. The app grabs the weather from one of 3 weather services; so don't complain if it turns out one day to rain and the app only says it's cloudy - weathermen do make mistakes, just like your local tv forecast.
6. even if i have paid for it.I /think/ this is a unique app; haven't found another one that mixes your own wallpaper with weather.
7. I consider this app to be money well spent.I really like the effects but it won't let me take the survey, or share it with my friends, or invite my friends, and those are the easiest ways to earn points for the cooler backgrounds.
8. The greyscale effect for when it is cloudy is simply on all the time, even when the weather is clear according to the app itself.
9. But still the best app with animated weather effects.
10. It's a decent live weather background, but you have to pay for almost every single weather effect (without which it's basically useless).
11. You can earn points for free to unlock effects, but every time I opened the app I lost most of the points I'd earned.
