I am building a fitnessapp which will focus on running. I just want to know is there any benchmark for android apps in terms of memory usage, CPU tune, RAM usage and network track so that i can compare the performance of my app to the benchmark and optimize it with respect to that.
If you want to optimize your app, you can use Android Studio Monitor

Memory usage and performance differs device to device. Do not take Other apps as a reference. It can be misleading. Optimize your app performance and memory usage as possible you can.
