International sanctions imposed on Iran over the last two decades have made access to technology difficult for Iranians.
While much of the world has taken advantage of the creation of iPhones and technology platforms like Netflix and Uber, Iranian citizens have been somewhat left behind in rise of the global tech.
Restricted access to mass market apps and platforms, however, has prompted developers inside the country to get creative and meet the growing demand for new technology from Iranians who want to order food and transport from their phones, and watch movies on their computers.
Many of the most popular apps in Iran are eerily similar to those at the top of the charts in the West, often using similar color schemes, fonts, and interfaces to their Western counterparts.
For example, because of sanctions Iranians aren't able to access Apple's App Store, but they can use Sib, an Iranian app store with an apple for a logo and a name meaning "apple" in Persian.
Here are a list of popular Iranian apps and their Western counterparts side by side.
There are several messaging apps on the Iranian app market. They work in a similar way to applications such as WhatsApp, one example is iGap.
Domestically-made messaging apps such as iGap are steadily growing in popularity in Iran, according to a report from BBC Monitoring.
Aparat is a video sharing website and mobile application on the Iranian app market, it works broadly in the same way as Youtube.

Bike-sharing app Bdood, which translates into English as "without fumes" allows people in Tehran to rent bikes around the city. It aims to bring a more eco-friendly mode of transportation to an infamously polluted city.

The orange and silver color scheme on the bikes is strikingly similar to that of Mobike, the Chinese bike-sharing giant.
Taxi hailing app Snapp is one of the most successful tech companies in Iran.

Snapp also has a subsidiary application Snapp Box, a service whereby users can send food or other items to another address.
