I want to know, if there are any way to get notification when I entered in any marked geo area.
For instance when entering a mall, I want to push to devices a notification to download a specific app.
I know, it is possible with a third party app, that will read GPS coordinates, and then check is user location within specified region but I want to do this without creating app.
Some where I heard it is possible with DSP (Demand Side Platform).
Can any one suggest me regarding this, or how can I achieve my goal?
