I am looking to have a versatile mobile/tab/ipad and in some instances a base application to be built. I want to be able to customize the features by being able to add and remove functionality by using a gui, also to change look. Including the functions below I want to be able to send txt/sms world wide free, with video or pics. in certain instances gps location can be activated, etc. To a point of being a fully functioning texting social, dating, people locator app too. IT MUST BE COMPATIBLE or native ON IOS/DROID/WINPHONE/TABS/IPADS AND MAYBE BB. All graphic design ideas and logos will be the responsibility of the designer. . In the US the police, truckers, firemen etc use the phrase "What is your 20?" indicating a request for location. I need to create an app to accommodate the idea. (my site and app is [url removed, login to view]). It is to have all regular functions of a regular navigation application, voice, alternate routes etc. Hope fully I can explain the concept of my needs in a few steps, then bellow I will add a short conversation indicating what technology I would like to use, or any other ideas. I will use the Letter (X or X1, X2,X3 the numbers to just indicate multiple users. Y to be used as a static point or address or final location.) The mobile apps should work on all platforms, android, bb, ios, windows. This includes a website to coordinate with the apps. If you cannot create a website indicate that in your quote, I can split the job. [url removed, login to view] user x and x1 are to meet, when the app is active on both devices it will show the physical location, approx distance, time and direction to travel and indicate whether they are getting closer or further apart. 2. Scenario, Y is fixed address X is the "local pizza delivery guy or who ever" x and y can see each other, distance, time direction est time of arrival (Just a side note, I called a cab the other day, the company said the cab as about 2 miles and 5 minutes away. Had I know this was a lie, I would not have stood outside my house for 1 1/2 hrs) 3, Scenario, invite sent out to multiple guests, unlimited number of X's and their location to Y. 4. The app can be turned on and off at will by either party. 5. The app is pertinently on to track location of user, ie. an employer to track location of employee, with alert when phone is turn off or goes dark. 6. Website users can create an account and add location and invite others to join web or add app to mobile device. (7. In addition it should have options to show and search for food establishments, fuel stations, lodging and coupons. I ALREADY HAVE THE DATABASES FOR THESE).
