If you want to see how the still under-development Hello Parkville app will work, go to Real Art Ways at 5 on Friday.

This app will send push notifications to nearby devices that have downloaded the program. It will provide a list of events, entertainment, and discounts within the Parkville neighborhood.

The “beacons” — 100 in all  — that will detect when devices are in the vicinity will be managed by the City, and those nonprofits and business owners who purchase them for $250 apiece. This will entitle the business/nonprofit to use the beacon for one year.

A Community Development Block Grant has funded the app, which is part of what the City calls “a larger business and community development strategy.” The City says it is seeking ways to expand so that similar strategies are used in additional neighborhoods.
