What is the smallest custom Android ROM (Android 4.0 or higher)?

PT — Aug 30, 2016 05:59PM BST

I need a minimalistic custom Android ROM which has a lot of RAM free for use because the app Map My Tracks needs a lot of RAM. I want to only use my phone for one thing and only have one application installed on it. I will install the app after I install Android on my phone. What is a custom Android ROM that is the smallest of all?
My phone is HTC Wildfire S.
