    We have a service which captures SMS and MMS messages on the Apple iPhone but does not capture iMessage. If the user (Admin) has a Mac they can use Apple Configurator to disable iMessage or use a large MDM provider like Air-Watch or MobileIron to disable iMessage. If they do not, then they need to do this on the device. We provide our solution to companies who are regulated by the government to capture their messages so we cannot depend on the user to disable the iMessages - even if it&quot;s company-owned. We are seeking someone who can build an application which would be integrated into our existing SQL .NET backend (which does reporting and archiving of the SMS/MMS) to shut off iMessages.

    Need a web-based mobile app that enables small groups of 6-10 users each (called tribes) to collaborate with each other; including sharing notes and a &quot;calendar&quot; where each member would commit to &quot;x&quot; within a 2-4 week span; and then the &quot;calendar would reset - but retain the history. To facilitate this strategy, SOFT provides a simple phone app for each tribe and its members. Disciples post their “serving” intention in the app, share before and after thoughts with each other, and at times, encourage each other to stay on track. The SOFT app also sends-out handy tips and friendly reminders. After completing a serving deed, a disciple simply updates his/her status in the app. The SOFT app can be programmed to reset at either 2 or 4 week time-frames; at which time tribe members make a new commitment to themselves and their tribe for the next time-frame.

    The app will be called FLOW. It will be a content based app where people can sign up to the categories of news that interest them the most. It will include videos, articles and photos. It will be the most popular news from the day in that category so stories with a certain amount of hits will be shown and will only be on for 24 hours. After 24 hours there will be a new lineup of popular news from the day, similar to say snapchat once people have read the article or seen the video once they aren&quot;t going to watch it again. It saves the consumer time, instead of reading and sifting through all the news to find the information you like to read. With FLOW it will all be categorised and come through on your App, it will be a quicker and easier way to read your favourite news. I am aiming to transform the way news is read and consumed by giving people what they want to know about.
