The concept of the project is to allow users to write an sms, and decide when it should be sent and to which contact.
For example, i write an SMS text, set the schedule for it to be sent Tomorrow at 13:30, and choose from my contacts list a person or multiple contacts to send it on that time.
User have 2 options to choose from when setting the SMS:
1- To set that the SMS will be sent automatically at the chosen time without any alert and recieve a confirmation that the SMS has been sent successfully.
2- At the chosen time a reminder will pop up for the user, asking him if really to send the message or dismiss it.
