I also use 3D touch many times every day. Mainly for mobile payments, example: 1. Pay for bus fare: unlock->find app->3d touch->select "show payment barcode" 2. Instant payment in restaurant: unlock->find app(e.g. wechat)->3d touch->"show payment barcode"/OR "scan barcode" to scan restaurant's bar code for payment

Without 3d touch you need one more step to open the app, and maybe more steps to find menu for payments(depends on apps you use)

edit: just found some apps(not all) provide widget to access features like payment...
