Location: New York City

Bio: Rosalin Siv is the founder of The Evercake, a website where you can order her beautiful homemade cakes and have them delivered to your door. The buttercream-based frosting keeps the cakes from being overly sweet, and each design is beautiful and detailed (order at TheEvercake.com).

Square Point of Sale: Square is so great for sending invoices on the fly and I love its user-friendly interface. It helps me manage my online payments and gives customers options for how they want to pay.

Nest: My Nest Cams are my eyes at home when I can't be there. I have two cameras set up, and the app allows me to see what is happening in my son's bedroom and elsewhere.

TikTok: TikTok is a must for boredom and general trend watching!

Calm: Calm is a great app when I remember to use it. I mostly use it to help me relax in an airplane or right before bed.

JOE & THE JUICE: This store is where I get my coffee if I don't have time to make it at home. I can only go to places that offer oat milk for my morning lattes.

YouTube: YouTube has become my best friend since I had a child. My son uses it to watch Monster Jam truck rallies, and I use it to get a ton of cake ideas.

TaskRabbit: TaskRabbit is great for finding someone to help with random errands, both professional and personal. I have had some amazing hires off of TaskRabbit!

Yelp for Business Owners: I enjoy YelpBiz because it is so easy to use. When Evercake gets a good review, I am pinged here, and I can read the comments right away.

Citizen: Living in NYC can be unpredictable. I started using this app to keep track of any disturbances happening in my neighborhood, and I told my nanny to do the same. I do have to turn off the notifications from time to time, though, because it can be a big distraction.
