### 5/5 — App is user friendly and perfect for fishing

*2021-09-10*

Great job with the app! Plenty of areas and easy to navigate

### 1/5 — Horrible

*2020-03-01*

Deleted and redownloaded 3 times and every time I hit settings the app closes. Horrible app.

### 5/5 — Can’t live without this

*2019-05-21*

I can’t tell you how many times this service has saved our Trips!!!  Thank you!

### 1/5 — Low quality and unreliable

*2018-10-02*

I was very excited when I first downloaded this app then came to realize after using it for year I would not be renewing due to the majority of the days I try to get information it’s only listed as a quality of two stars  which is very spotty. Maybe acceptable for early 2000’s but any other apps seem they may be better especially for $100 a year

### 1/5 — Used to be good

*2018-06-23*

The chloro charts used to be updated well. Lately they are barely showing anything. Not worth the money as you can go to tempbreak.com to free temp charts. Will not re subscribe

### 1/5 — Junk

*2017-09-18*

Can't get the darn thing to pull up maps. For $100, you might at least expect something to work?!

### 2/5 — Perfect App

*2013-07-11*

This is the perfect app if you love apps that crash all the time and don't work even once.

### 2/5 — US Centric ! Duh

*2013-04-24*

Sick and tired of software thats solely focussed on only the USA. Give me a break. This might be handy if you only live in costal USA. Rest of the entire planet - utterly useless.

### 5/5 — A must have

*2013-03-30*

After spending a couple hours playing around with the features, I could tell that this app is gonna help me more than I can explain. For the past few years I've been hoping terrafin would get an app and now that they have, there's nothing stopping me from making each trip a good one. I'd highly recommend getting this app

### 5/5 — Great!

*2013-01-27*

Works great! So nice to have the charts right at my fingertips. The GPS is a nice function, get to see exactly where you are on the chart.
