Boat watch

25th January 2018, as I said I only want to watch one boat, and the boat has disappeared from the start it’s no where to be seen, and I’ve been on this app on my phone and the iPad for 4 days, using this, and this is an update on the latter review.... I still can’t find my boat .... Are they all dead?? Has it sunk? Did I miss the News or fall asleep.... I hope not, I’ve no idea how to find the boat, you find it let me know where it is. I’m sure you will you have a much better package for searching boats than i do, you made it after all.

I wanted to track the boat to keep updates day by day to go along with wedding photo album as it’s a Honeymoon Cruise, a once in a lifetime trip.
Still not happy. Still 1 star...*

UPDATE ^^^ above.........
Slow to load and quick to take your money on an upgrade, you seem to be only able to watch one craft BUT loads more if you UPGRADE ... er no, I only wanted to watch a cruise ship to find out its locations I can only get it’s starting point, but if I upgrade for a £5 I can get heaps , for god sake let me get used to it first and upgrade later, very unfair...... and I only wanted to watch the ship for two week. The phone over heats on loading up a page ... chug chug struggle.... OFF ...
Why don’t you pop in for a cup of tea or coffee we can chat.. £5 a cup ... thinking about it though arn’t you ... I’m not paying £5 a cup .

Developer Response

Thanks for taking the time to leave a review - you can see unlimited boats in the app without upgrading, the upgrade allows you to mark more than one as a "favourite" to find it again quickly. Appreciate your comments about the upgrade prompts, we'll take a look at that and see if we can provide a better "free trial" experience.


Great free app

We live on the Isle of Wight, and love watching the ships passing our home. This app lets us know what we are seeing, and works perfectly, giving us loads of information. We've used in loads of other locations and it's worked perfectly at those as well. Don't know how it compares to Marine Traffic, as I've never felt the need to improve on this free app by paying for a different one. As for the mapping not being up to date, it appears to use Google satellite imagery, so it's as up to date as anything else. A great free app!
