After using this watch and app, I gave up. Just swam 2000 meters, I got a record of 2 laps. Biggest flaw is inconsistency. Sometimes works, most time does not. I don't know why. Tech support of the app has not got the answer. Overall experience sucks.
Been using this application for a couple of weeks now. Having a set workout everyday is a great motivator and all the organization aspects are excellent plus.
From a swimming point of view, the watch records laps and distances correctly and it is a major advancement from previous generation swim watches. There are problems however:  the watch is too mechanically sensitive and is easily turned on even when it is just being moved in a bag;  I have discovered never to effect data transfer unless a good signal is available (curious);  unless very well charged, the distance count doesn't work. Charge fully every time before swimming;  the data to Google Fit is not always transferred. Data is very easily not recorded or lost, but all in all the watch after some weeks' use is promising.
The app is really cool. It has a modern design and it was easy to set up. Of course you need a Swimmo watch for it to work, the features are exclusive to the device. Overall a great experience.
I bought the swimmo wach but I can not conneted to my phone that is android samsung 7 it is impossible. The wach work itself great but no connection.
Love this app. Keeps track of what I do. All you need to do is swim and everything comes alive.
