Simply Nailogical

Rotenberg was born October 17, 1988 in Richmond Hill, Ontario, Canada. She has one sister, Jennifer, who is frequently featured in her videos. From the late 1990s to the early 2000s, Rotenberg starred in fifteen commercials for children's products including Furby and Fib Finder. At the age of 13, Rotenberg played the role of young Sophia in the 2002 film "Charms for the Easy Life." (Mimi Rogers played the adult Sophia.) She eventually stopped child acting to focus on school.

In 2014, Rotenberg received a master's degree in sociology with a concentration in criminology from Carleton University.

Blogging

Shortly after defending her master's thesis, Rotenberg launched her Simply Nailogical blog in February 2014. Contrary to her videos, Rotenberg initially posted pictures of her own nail art. Her blog has been inactive as of June 2016.

YouTube

Rotenberg launched her first channel, Simply Nailogical, in June 2014. She initially focused on short nail art videos that were less than a minute long. Eventually, Rotenberg became more outgoing on YouTube by showing her face in videos and making her tutorials longer.

In June 2016, Rotenberg posted a video of herself applying over 100 coats of nail polish titled 100+ Coats of Nail Polish #POLISHMOUNTAIN. Her video quickly went viral, and her video was copied by many other YouTubers, such as Jenna Marbles. The Daily Dot praised Rotenberg's video, calling it one of 2016's most popular video trends. Soon after the video was posted, Rotenberg's subscriber count had doubled. Her video was featured in the Fine Brothers' College Kids React series in August 2016.

Since her viral video, Rotenberg's main channel primarily focuses on nail art tutorials, nail products, reviews, beauty tutorials, and anything related to holographic colors.

In September 2015, Rotenberg created her second YouTube channel, Simply Not Logical. Rotenberg began posting videos on Simply Not Logical in August 2016, with her first video being titled Simplymailogical #1. On Simply Not Logical, Rotenberg primarily posts vlogs and content outside of her usual nail art tutorials.

In May 2017, Rotenberg and her boyfriend raised $25,000 for the Ottawa Humane Society by selling merchandise with their cats, Menchie and Zyler on it. As a result of their work, a room in the humane society was named after Rotenberg's two cats, Menchie and Zyler.

On August 19, 2017, Rotenberg announced that she would be giving away one semester's worth of tuition to a subscriber that is currently enrolled in a Canadian college or university to motivate them to pursue higher education.

Rotenberg resides in Ottawa with her boyfriend, Ben, and her two cats, Menchie and Zyler. She currently works for the Canadian government.

Following her viral videos and newfound YouTube popularity, Rotenberg was nominated for Breakout Creator at the 2016 Streamy Awards. She lost to Lisa Koshy.
