TelloFpv gets updates every week or two. If you are in the Beta test program (open play store, go to TelloFpv and scroll down for invitation) you see updates every couple of days, or sometimes every couple of hours (like today).
This happens automatically unless you have opted for manual updates (in that case it's your job to keep up to date)
Ryze Tello app is eerrm... different. Updates every couple of months, and most often better to stay clear.
Sorry for the confusion everyone. I'm new at this and not much of a geek. Just trying to find a new hobby. Many times trying to find answers through other peoples discussions I find their conversation is often way above my knowledge. I'm learning. Thank you for the help.
