Is it possible to create geofencing in ionic app

Hi, Please suggest me, is it possible to create geofencing in ionic 1 with angularjs. My client require geofencing in his application, which was created by past developer in ionic version 1 and angularjs. I don’t have too much time to migrate the app with latest ionic. Also I don’t have experience in ionic 1 and angularjs. I am working in ionic 3 and angular 4. Please help.

Just a quick google search (3. result)
