GPS advice

Long story short. I have a Lowrance depth finder I bought three years ago for the sole purpose of ice fishing. I got the elite 5x. X meaning no gps on it. Then last year I got a small fishing boat and realized that while the lowrance was great, I needed a gps to control my speed and location better. Do I am wondering if I can just get by another year or so and just use the gps feature on my Samsung phone. So what I am wondering is what gps app do you all use? Which one should I look at! In your opinion which is worth the money?

here is one to try
https://play.google.com/store/apps/developer?id=Navionics

another one to look at
Gps Nautical Charts

look these up on you tube

I just found this app it looks OK

I just put it on my GPS Android Tablet

I’m going fishing Wed. I will see how it works. it is free.
