Implementing geofencing into your application can be challenging. I know because I did it for project for a lack of moderately priced and easy to use tools.
Thus, would you be interested to use a super simple service that takes your geofences and location data via API and notifies you via web hook, Zapier, etc. when a geofence is entered or left? What use cases would you see for your application specifically to enhance user experience with geofencing and would you do it if it was simple enough? Really looking forward to your feedback.
I already made a landing page for my potential project on https://locationbear.com/ to line out what my goal is.
