I created new icons so all set of icons used on this project have the same thickness and style.
The search screen was changed and the search definitions was improved so the user can have more control over the app.
I redesign this screen as you can compare the old and new versions below. The most important features (My Sales Ads / Save Sales Ads) were moved to the top and less important content was kept on the bottom. I added a button to create a new sales ad. This way the user can have one more way to create an ad besides tapping on the menu and then tapping on the 'Create Ad' link.
Not much was changed from the original design. I created new icons with the same style of the icon set and added more information on the seller that was requested based on an user research and on reviews from Google Play and App Store.
This screen was also changed to a better design.
As you can see here, I changed this screen quite a bit. The information here was redesigned to best displayed for the user.
The Chat is one of my favorite parts to redesign on the whole process. While I was doing my research to start the redesign of this project i stepped upon some comments about the information exchange when you're using the Chat feature on the app.
When you start a conversation with someone about a desired product on the older version you weren't able to get any information from the person that was interested on your product. On my design, we have 2 types of screens. The screen that you (Seller) sees with the information of the person interested on your product, and the screen that the interested person sees with only the product information and nothing else.
I create this screen because on the other version if you needed to contact the app you will be redirected to your e-mail app. On my design if you need to contact support you just tap on 'Support' and you go to this screen with all the fields to fill up and send your message.
I always start all of my projects with a rough sketch writing down all the information and workflow of the project.
The design is just the final layer of layers of research and wireframes on the project. Here you can see my wireframe.
