Not sure about macOS (don't use it myself) but for Android I like these two apps:

Glider: https://play.google.com/store/apps/details?id=nl.viter.glide... (open source, also on f-droid: https://f-droid.org/en/packages/nl.viter.glider/)

HACK: https://play.google.com/store/apps/details?id=com.pranapps.h... (not open source afaik, but more customizable)
