I am currently working full-time as an iOS developer at Navdy.com
Keycash is an iOS custom keyboard that allows you to create payment requests almost anywhere you can type.
Update (6/6/15): I have added an iOS/Watch application + Chrome extension.
My current project and first publicly released iOS app. I spent a while developing this shopping application from the ground up. After continued usage, ShopOrNot develops a style profile for the user and provides them with recommendations.
Please get in touch, if you want to discuss anything.
