An Android app is great for convenience and speed since it will not need to load in a browser like a mobile website. Apps usually store data locally on the phone so that if they are shut off at some point, there will be no need to refresh everything again when it comes back on - so you can go right into the app with all of your information and have access to the same thing as before. That way you don't have to worry about cutting out in between activities. The other best thing about an Android app is the notifications system. Many apps come with built-in notification systems where users are notified by alerts or sound once it has been updated- I think it’s a good idea to get your mobile app developed by an android app development agency rather than outsourcing it to freelancers.
