Gelsin Mobile Application Project Details “Gəlsin” is an innovative grocery shopping app developed for IOS and Android mobile platforms. It was build for our client who was planning to bring together all local grocery shops and make it easy for the people to shop through their mobile phones. It is a multifunctional application with several features dedicated to enhance the user experience while also making it easy for the admins to manage the back end of it; such as adding or removing stocks. To further augment the product, we have developed a courier app, which allows postman to update the status of the delivery along the process. The application was successfully accomplished with the great satisfaction from the client..
