RC App on older phone & 2-way radios

My wife and I have the RC App on our new Galaxies and it works great.

I charged up one of our old phones, a Galaxy S5 with plans to let our 13-year-old daughter use it on-board so she can get a hold of us with the RC chat feature.
However, I can't seem to find the correct RC app with that phone.
Does anyone know if the app is only available for newer phones?
Has anyone else experienced this?
And I guess, is this a good way for the kids to stay in contact while on-board?

I've though about buying some two-way radios if we can't get the app to work. Anyone have experience with them on-board?

We'd like to give her and her 11-year-old sister some autonomy, but want them to be safe and able to get a hold of us and vice-versa.

I found that the app requires android 7.0 or newer.

Here is a direct link to the Google  play store

For texting, what ship are you sailing on? That feature is only available on select ships. You could still use FB messenger or WhatsApp

Disregard the sailing question, I found your  post that you are sailing on Harmony, which I believe you can text in the app

The app works on an S7 but an S5 is getting kind of old.

Yeah, dug it out of the junk drawer, lol. 
We've always said wait until high school, but with this trip coming up and a few other reasons, we've decided to break down and get her a cell phone a year early.
Any experience with two-way radios on board?

It's my understanding that two way radios are considered contraband and will not be allowed on board.

I've used them before without issues (although they didn't work well with all of the metal around), but that was more than 10 years ago. I'm pretty sure the policy changed after we used them.

I have brought a set of walkie talkies on board several different Royal ships, and they have worked great.

As far as two-way radios, ugh. Don't be those people.  They are extremely annoying to be around.

Ever been annoyed by someone using their cell in speaker phone mode in a public place?  Walkie Talkies are even more annoying because they squawk and have static.  Please don't use them.  Everyone around you will hate you.

I've seen people with radios a few times. More in the past than recently. Never bothered me.  They are no more annoying than oblivious people with phones stuck to their faces all the time.
