I am developing a small dictionary app by using react native with expo.

As I am compiling to Apk file. The size goes up to 30mb and after having installed on a device, it goes to 80mb.

Is this normal?

Are there any ways to reduce the size of the app?

Thank you guys.

For android APK bundle using expo, you can use the following command:

expo build:android -t app-bundle

The size will be much smaller once you upload it to the play store. This is relevant for React Native SDK 32 and earlier.
