Must have for millennials

First off, I have never left a review before even though I’m glued to my phone all day. I downloaded the public app a few weeks ago. My account was not approved instantly (typo on my part, I found out later) and after a few days I emailed the support team and asked for help. They responded in like, an hour, gave me instructions to get trading, and was then approved right away.
Anyone under 40 with disposable income should, IMO, be investing directly investing in the market instead of relying on 401ks and other group plans. This app lays out all the info in a very intuitive fashion and within a week I was able to, with ZERO prior knowledge, navigate the app effectively, and the community of investors on the app are a fantastic source of investing advice.

This is not a day trading app and the various transactions can take time, but by keeping money in your account without spending it allows you to execute buy and sell orders quickly, though the money may take a few days to get back to your public account. I am usually able to make two transactions per stock, per week, which is more than enough to react to any big market changes. The fact that you can invest whatever amount you want is huge. Amazon’s stock at $2.5k may be too much, but Public allows you to purchase slices of stock in increments as low as $5.
I would HIGHLY recommend this to anyone with some extra cash and half a brain.

Public is the best!!

Just want to say that I’ve had nothing but a positive experience with this app. I thoroughly enjoy the social community aspect which sets it apart from other apps out there. It helps to get an idea of which companies people are investing in. The community as a whole is very friendly and are willing to help others that are newer to trading/investing. You can buy fractional shares with as little as $1! Which means anyone can be an investor. Much better group than Facebook groups. They actually care to help.

Smooth interface to navigate through, and simple for any beginner. They have themes that group stocks together in case you want to peruse through their collection. The Public Team is very responsive if you have any issues with your account. The longest I’ve waited for a response was 1 day. They have excellent customer service and keep updating the app to keep those pesky bugs away. I would HIGHLY recommend this app to my family, friends, and friends friends. I would give them 10 stars if I could. Keep up the great work!!!!

Incessant Notifications

The interface is good, but I can’t abide an app constantly sending me useless and incessant notifications. Even if you have all notifications turned off within the app’s own settings menu, you will still be bombarded daily with alerts that have zero relation to your portfolio or interests. Public lacks an honest notifications interface and merely has the appearance of granularity. The reality is far from it. I had to take the nuclear option and turn off all notifications at the iOS-level setting, meaning that I have to sacrifice the few notifications I actually do want: important notices about my account. And it’s all because all of these spam notifications that Public won’t let users filter out. The app itself is great, but I don’t need more spam in my life and the way they handle notifications feels downright gross. It’s a low-brow way to demand attention from their users and up their “engagement.” I expect this kind of bottom-feeding dark UX pattern from apps like Facebook, but not from a supposedly social-conscious app like Public. For people who don’t want to spend every day being reminded or spammed into messing with their investment portfolio, it becomes a huge turnoff and has led me to stop using Public. I recommend you avoid this app and use another service like Robinhood instead.

Hey Magast91! Thank you so much for your feedback here. We are so sorry to hear about the frustration regarding notifications. This is definitely not an experience we want anyone to have! Our only goal with notifications is for them to be helpful and informative, so we are definitely eager to help get this sorted for you asap! We tried reaching out in the app to help, but we weren’t able to find anything matching your username here. Would you mind please sending us an email at or message in the app chat so that we can look into your account for you? Thank you so much for your help and patience here! We will be on standby!
