Freelance, for anyone.

Once you've downloaded Callmart, open the app on your phone. Create a Callmart listing for anything you wish to sell - whether it be advice for other computer science students, or homework help - your freelance job is totally up to you.

An informative but brief title and description for your listing will not only be more pleasant to users, but also help you convert people from just viewing your listing to actually buying it. When you've come up with a title and description you're happy with, make sure to choose unpixelated, clear pictures for your listing as well - you'll separate yourself from the rest of the listings on the marketplace!

As long as you're within the app's limits for price per minute, you're free to come up with a price for your listing by tapping on the custom option on the price drop-down menu. Knowing about the optimal price per minute for your listing takes time, so you're always able to go back and make changes at anytime you want!

Value for Computer Science Students

Computer science students can easily promote their freelance listing by using Callmart's share feature. This will provide you with a URL unique to your listing and shareable with just a few taps on the app after you create your listing. In order to effectively promote your listing, we recommend posting your URL on sites like your school's website, or Facebook group!

Apart from English, our app is also offered in 5 other languages - Japanese, French, German, French and Spanish. Additionally, we support transactions for over 135 currencies! Anyone from anywhere in the world is able to use Callmart.

For every single call you sell on Callmart, we automatically charge buyers for every minute. Therefore, you get your money on the app as soon as your call has finished! No need to do anything else.

The Optimal Freelance Job

Callmart isn't limited to computer science students in a specific country; it's made for everyone. A freelance job that encourages connecting with people on the international marketplace is something only a very few apps like Callmart can provide. Make your listing public to begin sharing your knowledge with the world!

Our app charges a 3% service fee for every call on the app, in order to maintain and improve the quality of our services. Stripe, Inc., the third party online payment processing provider the app uses, will charge a separate fee as well.

In whatever situation you're in, you can use Callmart. Whether you've got a minute or an hour to spare, you can make money so long as you pick up your phone! Whenever you like, you can transfer your earnings on the app to your bank account.

Callmart is a global C2C marketplace app that connects computer science students with anyone through charged phone communications.
