StockWarn: Prices via Voice

Your favourite stocks on the markets updated via voice.
Have you ever thought you could listen to periodical stock prices updates rather than manually checking them on your phone or computer by the usual time consuming way ?
The app keeps monitored the stock prices of interest and gives you voice updates on their prices and percentages.
Use the earplugs or speakers and while listening to other things, while driving, or while working at the computer you can have periodical updates minimising interruptions to what you are doing or listening to.
The app gives periodical updates on the UI and if enabled by the user, via voice.
You set up the time for the periodical voice update in minutes ( min 10 minutes ).
There is also a setting about threshold percentage change crossing since last update.
The app will trigger an alert if there is a sudden steep change in the stock price crossing the threshold. A voice will tell you about this alert type.
This checking is performed once per minute, provided updated data from source ( Google Finance ) is available.
In general the source of data is Google Finance data so the latency is the latency of the update available from Google Finance via Google Sheet.
The app creates a Google Sheet on your Google Drive in order to fetch the stock prices of your interest from Google Finance.
That's why at the first use after installation, during the first monitoring attempt, the app will ask you about "Logging in with Google".
The app works also in the background, when you are using other apps, or even when your phone's screen goes dark to save energy.
Carry on what you are doing and the app will update you about the stocks!
