Week 30 Featured App: Stacks [Promo Codes]


Promo Codes added Saturday, November 16, 2013

Stacks ($1.99) is a new, simple gesture based currency conversion app. Stacks is well designed and equipped with a clean, smooth interface. The app includes features like bookmarking past conversions, an interactive historical chart (rotate phone), and real-time exchange rates.

Stacks was created and designed by young development team WapleStuff. We reviewed the company’s previous app Calzy, a while back. The idea was to build a quick, simple and straight forward currency converter optimized for iOS 7 and 6, it includes translucency, dynamic type, parallax, and dynamic animations. The developers offer eight “themeable” colors to “match your mood and style”.


  • Beautifully designed functionality and interface
  • Sleek gesture based system
  • Supports over 160 World Currencies
  • Appearance is completely customizable and personal
  • Unique features: bookmark list, historical chart, currency rounding
  • Ad and pop-up free


  • Menus and functionality a bit unclear
  • Complete gesture interface not optimal for some users
  • Some competing currency conversion apps are free

Last Words….

Stacks is a well made currency conversion app. It has a nice design, works great and can convert over 160 currencies. The developers added a few nice unique features as well as the ability to customize the overall look and appearance of the app. After getting over the very minimal gesture and menu leaning curve, I would recommend the app to anyone looking for a professionally developed currency converter.
