woopy is a Universal App template where you can browse and post listings on the go, new or used stuff you want to sell. You can search for keywords or category, chat with the seller by his item’s page, log in with Facebook or email, like and share ads, and a lot more.
Besides uploading up to 3 images while posting an ad, This app allows you to also upload a 10-second video, this is a great feature that other listings classifieds apps do not have!
Users will be able to report ads or users and block/unblock inappropriate users to prevent getting chat messages from blocked people. They will also able to send Feedbacks to other sellers
woopy has also a verification email system, once a user signs up by email (not by Facebook), back4app sends a verification email based on the email address the user typed in the signup screen. People will be able to see if a user is Verified or not by entering his/her Profile screen.
The Categories names and images are stored into the Parse Dashboard, so you’ll be able to add new categories remotely without having to update the app.
Check its video preview to see it in action!

Since its backend is by Parse Server you don’t have to buy any domain/hosting, there are NO PHP files to upload to a web server so you’ll save some money for server side, also because back4app offers a generous free plan.

woopy is a native XCode project, Swift language, Storyboard, Universal, super easy to customize, backend with Parse Server hosted on

About Parse SDK and back4app

Read this article for more info about back4app and Parse SDK:

Can I host Parse Server on my own server?

Yes, although I don’t provide support for the setup process, you can read the official Guide here:

I get a Code signing error in Xcode 8.x

That’s a bug of Xcode 8 with macOS Sierra, check this sample video to see how to fix it:

How to remove AdMob banner ads

Check this video out to see how to remove the code that shows AdMob banners: Keep in mind that you must repeat the shown steps for every .swift file that contains this line on the top:
import GoogleMobileAds

What about free support for this template?

I can offer free support for bugs encountered in the original code. Instead, if you’ve edited the code and messed something up with it, I may apply some fee to fix it either via TeamViewer or by checking your app project files directly on my computer.

Should I use the latest version of Xcode to edit this template?

Yes, I always update my apps to the latest version of the IDE.

How to change images in the Categories class of my Parse Dashboard?

After importing the Categories.json file into your own Parse Dashboard, you have to double-click in the empty space between the edge of a cell and the blue image button to replace the existing images, check the screenshot below:

After importing Categories.json in my Parse Dashboard, I see no data

That may happen sometimes, it’s a bug in the Parse Dashboard, so in this case you must manually add rows and columns on your own.
1. Click Edit -> Add a column, choose String as type of data and type exactly category, then click ‘Add column’
2. Click Edit -> Add a column, choose File as type of data and type exactly image, then click ‘Add column’
3. Now you can enter the empty cells and insert the name of your first Category, doublie click in the empty cell of the image column and upload your first image.
4. Repeat the steps above for each category you want to insert in your Parse database.

How do I change the order of Categories?

The only way to do that is to remove all rows from the Categories class and add then again based on the order you want categories to be shown in the Home screen of the app since they get ordered by their ‘createdAt’ date.

Why do I need to have login from Apple Account in the app?

Yes, because from 30th April 2020, APPLE authorities restricted the apps using 3rd party login from FACEBOOK, GOOGLE etc should also integrate “APPLE SIGN IN” method in the app. For reference: APPLE SIGN IN GUIDELINES
