At 34 years old, Simply Nailogical has this physical status:
Rotenberg works as an analyst for Statistics Canada, an agency of the Canadian government. Her work focuses on crime statistics and has included analysis of sexual assault reporting amid the #MeToo movement. Despite lucrative success with her other endeavours, Rotenberg has expressed her desire to maintain her analyst work for reliability and fulfillment not available in her YouTube career.
Rotenberg's Simply Nailogical YouTube channel was launched with her first video on June 18, 2014. The channel was preceded by her Simply Nailogical blog launched in February 2014. She posted pictures of her nail art on the blog and on Instagram, and actively updated her blog until June 2016. On YouTube, Rotenberg initially created short nail art videos that were less than two minutes long. She later began including voiceovers, extending the length and detail of the tutorials, and eventually appeared on-camera. Since launching her channel, Rotenberg has branched out from nail art tutorials to videos about other topics relating to pop culture and nails. Her videos occasionally feature Rotenberg working with holographic items and she has referred to her love of these as "holosexual". Rotenberg uses the phrase "holo taco" in her videos to refer to holographic top coats and later named her own nail polish brand Holo Taco. The phrase came about due to viewers misunderstanding her pronunciation of "top coat" as "taco".
In June 2016, Rotenberg posted a video of herself applying over 100 coats of nail polish titled "100+ Coats of Nail Polish #POLISHMOUNTAIN". The video quickly went viral, and influenced many other YouTubers such as Jenna Marbles. The Daily Dot called it one of 2016's most popular video trends. Soon after the video was posted, her subscriber count doubled. Her video was featured in the Fine Brothers' College Kids React series in August 2016.
Rotenberg has two secondary channels: "Simply Not Logical" was created in September 2015 and primarily contains vlogs; the podcast "SimplyPodLogical" launched in February 2020. An April 2020 episode of the podcast featured Mazowita and Rotenberg interviewing Dr. Howard Njoo, the Canadian government's deputy chief public health officer, about COVID-19.
In April 2019, Rotenberg's Simply Nailogical channel was the 19th most popular YouTube channel in Canada with over 6.8 million subscribers and 1.2 billion views. J-14 magazine described her as "the face of nail art in the internet world".
On July 17, 2022, Rotenberg announced that she would cease producing videos for her main channel in order to focus on her personal life and Holo Taco. However, she will remain active on her secondary channels.
