The Stackables app just had an update and I have five promo codes to GIVEAWAY! With the new version, you can not only create your own custom formulas and save them, you can also SHARE them with your friends or between devices. Stackables is even asking for submissions of your customized formulas through the app for possible inclusion in their upcoming Featured Formulas category!
I went to work creating some formulas of my own and tried them on a few photos. By using the same formula on several photos, it's easy to create a series of images with the same look. I called this filter Lost and Found.
If you're interested in getting a FREE copy of Stackables, I have five promo codes to giveaway. Just leave a comment below and I'll give codes to the first five people who do so! If you miss out on the giveaway, you can purchase Stackables on The App Store here.
