Go to the Play Store on your Andorid and download ATAK-CIV (Civilian Use). I have found the same ATAK app on Android Galaxy S8s and S20s. There are a handful of RU-vid videos and Reddit forums discussing plugins you can add to ATAK to improve your overall experience. I have looked for ATAK on Apple devices as well and have never found them. Some guys are even figuring out how to connect their handheld Amatuer/HAM radios to ATAK now.
