The problem is that if you are calling me for a cricket match or any other yes/no voting situation, I dont know that you are calling me about a question, or if an emergency is happening and you are calling me needing some help. So even if I don't want to go to a cricket match, I will still pickup your phone call and talk to you.
Second, if cricket match was scheduled on Sunday morning and I've declined your call (means I'm not coming), but now the match time got changed to afternoon, and you call me again, then how would I know that there is an update in time? So, even though I'm available in afternoon, I will still cancel the call considering that match is still on Sunday morning. If you can change the CLI text with the Subject of Call, that appears on my phone, then i think we have an invention here.
EXAMPLE:
So you enter a queation and select the contacts and press call.
Each contact will receive the phone call and will see "Zahid +9233322233344: Cricket match on Sunday 3/4/2018 Morning at 9am?" on their phone screens.
Now if I press ACCEPT or pick the phone and attend the call, it will register as a YES to your voting result.
If I press REJECT or don't attend the phone, it will register as a NO to your voting result.
Now, if you get too many NOs, you can change the voting question and dial the group call again. This time I will see "Zahid +9233322233344: Cricket match on Sunday 3/4/18 Afternoon at 2pm?
And the call receivers can now again do a YES or NO after seeing this new update Subject of CLI on their phone screens.
I think it's a good idea with lot of corporate potential (people can schedule quick meetings without outlook or take a survey or the administrator can ask employees or school/college kids quickly and simply if they are safe after a shooting or bombing incident etc.). So basically this is a voting or a survey app using phone dialing system, and when the user picks the phone or accepts the call, that just means a YES, and then system will register the response and disconnect the phone, that doesn't means that the receiver can now TALK with the sender of the call. Because if 10 people say YES, all of them cannot SPEAK to the sender simultaneously. So be cleae, that this app doesn't let two people tall to each other, it's simoly a voting or survey app, that rwgiatwra yes or no, if one accept or reject the phone call, respectively.
Besides taking the survey from friends, also put these options:
1) Your APP is always FREE. But after the app is installed it will collect location data in real time, and will also ask for gender and education level and age of user and income and other details.
2) Based on the collected data, now you can allow the companies (premium paid subscribers) to dial people.
3) Companies can choose to dial people based on distance, location, gender, age, education etc. to run their promotions or targeted ads, or any kind of survey. Companies will also be able to send coupons or material or followup second or more calls, bases on the initial response to their original calls.
4) So as an example of calling based on distance, within 0.25 mile radius of a mall, all shoppers will get a message like (Would you like to come for a 50% sale at JunaidJamshed). And a coupon is then send to all the users who said YES, so that they can come and do shopping. Same thing goes for a movie theatre "Would you like to see movie Jurassic Park today at 5:30pm for $2, if user says yes, send them the coupon and if user says no, send them another call, asking if Jurassic Park 8:00pm show is better for them for $1.75?
Work on the details, be VERY VERY CLEAR and this can become really big and its a Good Idea (so many applications, like doing survey for college classes "Do you like to attend museums for a space exhibition" or running a promotion ad based on age or gender or location or education or income level and especially in security conditions like shooting in crowded places like schools, colleges, hospitals and the management can quickly do a safety count of teachers or doctors/staff or employees or student by typing in the subject "Are you safe?" and sending it as a group survey call to everyone. Those not responding or those rejecting or denying the call will be counted as potential victims.)
Hope this analysis helps.
