“Apple Inc on Wednesday removed an app that protestors in Hong Kong have used to track police movements, saying the app violated its rules because it was used to ambush police and by criminals who used it to victimize residents in areas with no law enforcement.”
f-droid lets you make your own apk repo and even share apks via bluetooth.
Nice! F-Droid is plain awesome. I’m so glad it exists, though I wonder if the HK protestors know about it and use it.
