Full description
JStore is a student made app that aims to provide a marketplace for students on campus of Jacobs University Bremen. Why we made this app? 1. To reduce email spams related to buying and selling items on campus. 2. To increase the chance of your items being discovered and bought by interested students. 3. To make it easier for you to find certain items that you are interested to buy. What are the features? 1. Email link login with ease. 2. Post items with a picture (from gallery or taking a photo inside the app), title, category, condition, description, price, and preferred payment options. 3. See all the items that are currently on sale and click to see the details of a certain item. 4. Contact the owner of the item with WhatsApp/Email by just clicking a button. Pre-filled text will show up. 5. Manage your items by marking them as sold or simply deleting them. 6. Filter items by price/date/categories. 7. Search items by title. Do we have more features to add in the feature? Yes! Many exciting new features are coming soon, including: 1. Notifications for newly posted items. Enjoy using the app!
