Netatmo Weather 4+

Even without HomeKit support, Netatmo Weather Station has proved to be the best product for Apple users in this category.
The configuration process, especially after one of the last updates of the app, is very intuitive and no longer requires using the Mac/PC for setup. Adding external modules is very easy too.
The only thing that makes the entire experience little less enjoyable is signal strength between the modules, so users should carefully plan the location of the base station and modules to keep the signal strength at highest level possible.

Couple words after 26 months. Still working well though after 10 months experienced an issue with PCB inside external module. Guilty - low quality varnish. Module stopped working due to moisture ingress. Varnish peeled off followed by corrossion. Fortunately I was able to fix it - damaged copper paths substituted with wires and covered with professional grade varnish, working well till now.
The application is intuitive, nice looking and responsive. Annoying is automatic scale in temperatures history. It should definitely have clear reference point at zero Celsius instead of bizzare values => difficult to interpret historic data. I would suggest getting rid of auto scale at all since temperatures ranges in case of either internal or external ones are relatively narrow. Fixed scale with clearly marked zero Celsius would be more practical.
Lack of Polish localization in case of gadget sold in Poland is obvious sign of disrespect to Polish clients. Very disappointing but I guess I should rather blame our government for bad law which allows for such practices. Anyway shame on you dear Legrand.

The app is almost perfect, but it would be even nicer with Polish language with it. Please, it’s not a big request...

And one more thing ;-) It would be nice to have an option to increase size of displayed weather information in app. All the best!
