A Flexible Life with Callmart.

Once you've downloaded the app, create a new listing to get started. As a mathematician, you can sell just about anything - for example, answers on how to solve a certain mathematical problem, or a listing for your clients to contact you whenever they want.

The quality of the image(s) for your listing should be as good as possible, so as to catch the attention of people scrolling the app's marketplace. Furthermore, a straightforward description and well thought-out title will make your listing more inviting to potential buyers!

You can either pick from one of the suggested prices displayed on the drop-down menu, or create a custom price of your own. Also, you can go back to your listings at a later time (after they've been published) to make changes to the price if you're not content with the response rate for your listing.

Merits for Mathematicians

By using Callmart's share URL feature, you now have a one-tap solution to promoting their services! In order to bring in more clients and buyers for your listing, we suggest posting your URL on any Facebook group for mathematicians, and also your LinkedIn page! Be flexible with where you share your URL - you'll build more buyers this way!

Not only Callmart supports transactions in 135 currencies of the world, it also comes in 6 languages at the moment: English, French, German, Japanese, Korea and Spanish. Why don’t you share your knowledge with the world and learn new things about yourself and the rest of the world at the same time?

All calls made via the app automatically charge buyers for each and every single minute of the total duration, meaning that you get your money on the app as soon as your call has ended with a buyer. Super convenient and hassle-free with no payment issues!

First-Class Flexibility

The app is the most creative flexible job to earn money on your own. Mathematicians can communicate with people from different backgrounds and countries by publishing their listing on the marketplace - a truly unique experience! Making your listing private, on the other hand, is useful if you want to limit your listing to people you know personally.

A small 3% service fee is all that Callmart charges for your transaction. Stripe, a third party online payment processing provider that we use, will charge an additional fee.

Use Callmart whenever you feel like it, or whenever you have free time - even if it's just a few minutes! All you've got to do is talk, get paid, then transfer your earnings to your bank account!

Callmart is a global C2C marketplace app that connects mathematicians with client through charged phone communications.
