Unity: Device Memory Profiler
List all runtime unity objects in your game on your target device in paged list without needing to connect it to a computer or a long wait. Use it to make sure the game is only running what you are expecting it to be running.
Find all unity objects for the classname as you mention in the first text box, from its module as mentioned in the second text box. For most of the unity classes, the module is "UnityEngine.CoreModule" with some exceptions such as for ParticleSystem, the module is "UnityEngine.ParticleSystemModule". For classes extending MonoBehaviour written by you, the module maybe "Assembly-CSharp". If you give an invalid class name (such as Object1) the text in the text boxes will turn red.
