### 5/5 — Ken

*2022-09-22, version 1.1.5*

Simple and accurate!!!

### 3/5 — Average

*2022-02-22, version 1.1.5*

If you look at a particular stock over a period of time like 3 months or six months there is just a graph.  There isn’t any price range.  You have to press and slide to see prices.  Just an extra step that others apps don’t require.

### 5/5 — Great simple app

*2022-01-10, version 1.1.5*

I like the simplicity, but the information layout of the app. I like how it gives the after hours update on stocks in real-time. My only request… Turn this into a widget, so I can see a few stocks just be turning on my phone.

### 1/5 — No iPad View

*2021-12-15, version 1.1.5*

Join the twenty first century and offer a full page view on iPad. Annoying little iPhone screen on iPad Pro 12.9 is a joke.

### 5/5 — Best Real Time stock quote app

*2021-12-08, version 1.1.5*

Stock Siren is the best real time stock quote app I’m aware of.  They even have crypto quotes.  You can track your stocks by % gains and it allows sorting options.  A fun way to track is by % gains because it feels your stocks are competing for the top spot on your list and daily rankings are constantly changing.   Unlike most other apps where the stocks are stagnant even as their % gains change.  
Only minus is that there’s a 15 minute delay for foreign stocks and bulletin boards.

### 3/5 — Need some help

*2021-03-31, version 1.1.5*

Need stocks in alphabetical order... can’t always toggle the stock charts... can you help?

### 5/5 — Easy to use

*2020-10-28, version 1.1.4*

I’ve been looking for an app like this for a while!

### 5/5 — Good tool

*2020-08-31, version 1.1.3*

In the short time I have had this App I have found it to be very helpful.

### 5/5 — Great App

*2020-04-05, version 1.0*

Use it everyday to track my portfolio.

### 5/5 — A MUST DOWNLOAD!

*2020-04-01, version 1.0*

I have been waiting for a watch list app for so long, this is so clean and user friendly and gives me everything I need!  I don’t love the standard stock market app on the phone as it doesn’t give me news or twitter feeds. This is really great and the sorting feature based on name and percentage is very helpful. The user interface is clean and easy to use to create a watchlist. Adding stocks takes one second and is not a hassle at all! Very well done!
