Update 25\03\2021: issue is still happening. Locks me out every month or so saying that I have an old version and needs to be updated but there is no update available. This is a bug that can be fixed. Instead of locking out users for using old versions just prompt then to update but still let them use the app. When this is fixed let me know and I'll rate the app 5 stars. Until it is fixed don't bother downloading the app.

The best app for predicting surf conditions. Nicely designed, very stable app without bulls***. Love that you can add your own spots and that they stay private. You can also switch between various different forcast sources. Keep up the great work (but don't forget to get some swell every now and then)!

While it has a great visual, it's easy to see that the app is abandoned and doesnt work properly with newer phones... too bad. Also only shows a few spots on New Zealand I got an S9

Was working fine but when I now try to open app it is saying that my version is old, and to update. When I then click on update now it gives me option to open app or uninstall app ! If I try to open, it takes me back to version is old message ! Please sort so I can rate 5 stars again.

Loved the clean design and the user experience is awesome. Pretty intuitive! with this app, I can see clearly my forecasts so we can prepare myself to do surfing \o/.

Generally a good app, I know a few people that use Sine. However, now the app is telling me I need to update it, but it won't update and the old version doesn't open. Fantastic 🙄

Keeps saying needs an update then won't allow me to update. This happens at least once a month. When it works I love it.

POS App doesn't even list my area! USELESS!

Good app, not sure if conditions match reality though.

Potential, but can't add a spot simply. Lack of ECMWF

Put in custom spots and none of them had a forecast even close to be accurate.

Keeps crashing when I want to add alarm. The rest is quite good

No Israels spots, but a lot of surfers here
