MixerBox TV: Taiwan’s news channels, sports, entertainment, and more, Live broadcasts. https://tvapptw.com/
Old Time Radio Player: listen to radio shows when there wasn’t TV. Abbott & Costello, The Shadow, and much much much more. Great to fall asleep to. Your parents will like it too. My dad (in 70s) listens to it every night to fall asleep. Brings back his childhood memories.
Star Walk 2: point smartphone into sky and see what stars, etc. should be there (if not for pollution, etc.). Educational for children and adults.
Zello: kind of a mix between CB and short-wave. Excellent on the ground reports from disaster areas. Random people chatting from around the world.
Relevant Radio: Prayers, Daily Readings, etc. Can recite/listen to the Rosary while driving or cycling
