The target is to develop two mobile apps.
One app for a person walking through the city. The person can find balls in the city (location based). If the person walks over a location the ball will be sucked into the app. He can click on the ball and see the details of this ball. Each ball contains a coupon (with a barcode). With this coupon the person can go to a local shop where he shows the coupon.
The shop owner uses the second app which has to be developed. With this app he scans the barcode of the first app. After showing the coupon details, the shop owner can redeem the coupon via clicking a button.
Server Side functionality (if we need them) can be developed by us.
We will also deliver the design of the app.
Some more details can be delivered in the negotiona phase. I put in the budget for small project because I don´t know how much effort you need to develop these apps. Please also send me an offer if the amount is lower or higher
