This is crazy timing because I just had the mirror experience while trying to find a scanner app for an android phone I wanted to use around the house as a smart home remote. The play store was a dumpster fire. I bought the Quick Scan app (Dev is iSolid) on iOS and was willing to pay good money for one on the Android phone too, but every single scanner app on Android had ridiculous subscriptions. A few were $20 a month!
Cooler control is great if you need to control the pump and fans of a CPU cooler. I’m not sure if it can do case fans like fan control but I just set them in the bios anyways.
