***NO CON...NO POP UP ADS***
It's really not fair for me to review this because I just downloaded a similar but far more comprehensive app...BUT I payed $3.99 for it. SpaceEffect is a great free app to use for cool effects though. To be honest, I would probably rate it a 4, but I'm upgrading them because this is one of the few "free" apps I've tried lately NOT to immediately either 1) bribe me to rate their app 5 stars to unlock premium features or even worse, 2) not even let you access basic features without the 5 star before you even get the chance to try it.
Yes there are ads in the free version, but they scroll at the very bottom, and use up very little screen space at all; they don't pop up and force you to watch some ad for a stupid, completely unrelated game. I've begun giving reviews of 1 star to any developer who tries this con and deleting their app. There are hundreds, in not thousands, of photo editors out there; save your money and time for the honest ones...and pay when you can (no, I'm not a developer lol)
Premium features look solid, too. YAY for HONEST DEVELOPERS!!
