As high school students, we've noticed the amount of things that students need and want from each other. Whether these items be used textbooks, SAT prep books, clothing, calculators, prom dresses, or even artwork, it seems that everyone had something they could sell that would benefit someone else. Many students created makeshift photo albums of the items they wanted to sell with captions of the prices, but were often inconvenient because these items often got lost on people's newsfeeds with other posts and even friend privacy settings. Criagslist was a little too unsafe for high school students to manage, and there was no real user-friendly way for students to manage their own markets.

How it works

There is really one main idea to Marketplace: buying and selling items in an extremely user-friendly way. Logging in and connecting with students in your school allows for safer transitions. If you are a seller, all you need to do is take pictures of the items you want to sell and write a price underneath. As a buyer, all you need to do is use the search bar to find what you're looking for and request an item. If you are satisfied with the item you bought, you may rate the seller with a 5-star rating system. With simple buttons and swipes, this app has a clean, simple, and straightforward interface that makes selling easier than ever before.

Challenges we ran into

Being able to integrate accurate intelligent search to find items was the hardest part. It was our first time integrating Azure search, but because of it we were able to deliver accurate search results to users.

Accomplishments that we're proud of

Catering to each other's strengths and weaknesses, and working together as a team. Also, the little things - even the five star rating features was something we were glad to implement. Even deciding what to do with the interface to make it as easy and accessible to users as possible was an accomplishment.

What we learned

As cheesy as it sounds, the importance of teamwork really helped us. We learned how to integrate cloud services into applications. But other than that, making an efficient and simple user interface was actually much more difficult than we expected. For some of us, it was the first time we coded Android applications instead of iOS applications, so there was a lot to pick up and learn.

What's next for Marketplace

First of all, we really want to make Marketplace available for iOS with the members of the team who are familiar with Apple products. We really want to be able to expand Marketplace to colleges and other friend circles. Also, just fixing up the visual aspects of Marketplace and adding little details - like push notifications, reminders, and other settings - that will clean up the details of the app as much as possible are something we want to look forward to.
