Ratings and reviews

When using the Android version of NestWatch in the field I often get multiple nest visits, sometimes 2, 3 or 4 instead of the 1 nest visit that truly occurred. I have tried airplane mode; I have uninstalled and reinstalled the app, but neither has provided a solution. Using the clunky app beats having to pack a clipboard, paper and pencil, but it is aggravating to have to check everything over on my MacBook Pro, making all the deletions and adding data that never made it to my desktop.

I'm trying to enter all the information for my Nest box trail at home before I go out. It's frustrating that I can't edit it. I would like to change the name of the nest, so that I can list each one with a number, since there are 14 boxes. I can't edit the nam, and it keeps using my home location. I have uninstalled it and will try again, but I don't know if it will work with my account that I already set up. There should be a way to delete a box without archiving if you make a mistake.

I love the NestWatch program, and the new design of the app is much more intuitive. It also seems to run more smoothly on my phone. However, it starts up in dark mode each time, which is very hard to read while out in the field. I keep turning dark mode off, but it's back each time I reopen the app. I'd like to be able to set a preference for which mode it defaults to, instead of having to change it every time.
