Apps such as Taskrabbit and Rewardable allow you to complete quick and easy odd jobs for people or stores in the area.

Taskrabbit focuses more on completing tasks for people in the area, such as getting their groceries or assembling furniture for them, while Rewardable can also help you connect with stores and businesses in the area and perform simple tasks such as comparing inventory between different stores.

Apps like these and other can provide tourists with a way to make money while abroad, since you would likely need a permit to actually get a regular job.

Btw, I want to visit Jarkatar
