Constantly asking for a sensor to connect. I just want to check settings or history. ### 1/5 — Datos *2022-05-22, version 1.1.0* El hecho de que la información sólo se muestre en el teléfono con frecuencia es un inconveniente, sería estupendo que también se mostrara en el reloj … Garmin, AppleWatch, etc. ### 1/5 — Bug application *2020-12-25, version 1.1.0* L’application bug et me dis toujours qu’aucun appareil est connecté alors que ma station météo est bien connecté et que je reçois les données. Un message d’erreur s’affiche régulièrement ce qui rend la lecture des données compliqué. Dommage ### 3/5 — Need to adapt to iPhone X screen boundaries *2018-09-09, version 1.0.21* I’d like to have my BL 300 working at full size. 5 stars product need a 5 stars App ;-) ### 1/5 — Extremely limited *2018-01-06* The app is extremely limited. It does not allow you to view recorded information in a meaningful manner and can only be viewed whilst the anemometer is on. Unable to get a graphical view for anything more than last 10 minutes. Whilst the anemometer is a good piece of kit it can only be used with the app which unfortunately makes it unsuitable. Will need to be returned. ### 1/5 — Bugs, lots of bugs.... *2017-04-15, version 1.0.20* Losing the BT connection with the hardware, tracking and saving not working, updating firmware gives a blank screen too. Even if these issues get a solution, too much limitations for personalisation of graphs, measurement intervals, export of data. ## Frequently asked questions about Skywatch BL ### What devices does Skywatch BL support?
