Eric and the Klaim team successfully used Dropsource to build, test, and publish their iOS and Android apps. The Klaim app is a marketplace that offers amazing deals personalized to your interests. Local shops or businesses create promotional campaigns and you get exclusive access through Klaim. In addition, Klaim has a loyalty program known as Koins.
Their Bubble-connected app includes geolocation, push notifications and social sharing as well as other native features.
A very cool app from the Klaim team that you should check out, good work guys!
