I need an iPhone app. I would like it designed and built. This app solves the problem to "did I just send that text to wrong person." I do not think there is the need for a back end data storage unless email only for signing in if need be but don't see this as necessary or future advertisement for expansion of idea apps I Have beyond this simple concept but same genre. However, the need to accept payments is crucial if payments are not done by third party vendor for renewal and/or originally buying. app would be downloaded to all devices iPhone, android, iPad eventually but ipone first. It would be downloaded to device. Use is unlimited contacts and/or pay per package for number of contacts protected. I don't think there is interaction between customer or a gay as I just see it working in the confines of own phone so doesn't require wifi or anything like that. Essentially, I have 2/3 ways of preventing erroneous messages being sent to unwanted and unintended contacts. . Each way is another layer and we can start with simplistic and add another layer on in successful progression. IOr lump all 3 and get it done from beginning.i have indicated expected cost but I'm hopeful it fall within category one less. Thanks for your time and consideration and any comments etc Landon p.
