I love this app. It's really relaxing to watch and can make really creative designs. I would give it 5 stars except for the fact that it hadn't been updated in 4 years. I don't know if you guys have up on the app or not but could you please update it soon? The app is still formatted to iOS 6 and iPhone and iPod 4s. It used to let me set a photo to use but now when I click to select a photo the app freezes up. Otherwise I love the app ☺️

Listen- oh younger ones here, STRESS IS RELATIVE! As you get older- your stressors will change, BUT- your ability & your tools for dealing with the stressors WILL improve. And kudos to you for recognizing this app as a tool for that! When you are young, you haven't gotten down the fleetingness
Of time, because you haven't lived long enough to get a good perspective on the multitude of changes that come with time. Things & situations seem like there is no change. But the older you get- the more you will see "this too shall pass". Nothing in life is forever, and your entire life can be forever changed in the blink of an eye. One more thing and I'll shut up. Your life will be so much the better if you chose to have happy, positive friends. Surround yourself with the people who will lift your spirit up- instead of trying to pull you down to Their pit. Case in point- the wise & sage 'relax'. Ooh- choked on those words trying to get them out! Good luck to you, and Godspeed!

Great Idea!!

I'm a student at a graphic arts school earning my degree in graphic design. This app creates some very interesting and striking pieces of art! I love how you can manipulate the "cracks" to appear where you want them, or how you can let the image reveal itself to you on it's own. You an also choose any picture in your photo album for it to grab a color scheme from, so it's lots of fun experimenting and trying to create different effects.

Great job developers!!
