Our SDK's average size is about 28mb including neural networks and architecture part for simulator support. The main reason why your app can be so big in size are effects.
For this reason you can face some issues with CPU, RAM overloading and device overheating. Moreover, App Store for example, can reject your app because of its size.
So, we highly recommend you to store effects on external server and load them from the first app launch. You can load them all or each separately by demand.
