Anyone please suggest me a free API to send push notifications to the user?
You can use Android's Firebase push notification which is ofcourse Free at certain limits. However you can try hands on Parse- server too.
No its not free now.Neither is the maps service.
Use OneSignal. It's popular among all platform. 😊
