Yes, our testers are all using the app. We are constantly making changes to it based on their feedback which is why we are not yet ready to release too much information. In short, you are able to select a pre-made grow recipe for the plant you have started. As it grows, you can track relevant data in the app and it will also prompt you with tips on how to improve your grow.
There will be information on how to properly top and trim your plants for sure. At the moment, the app does not require any special permissions.
