Via our App you can: - Activate your license to connect your sensor to PlanetWatch - Monitor Air quality around you - Help us build a global air quality network. Air pollution causes millions of premature deaths every year so air quality monitoring is essential yo protect everyone’s health. Currently, air quality monitoring is mostly performed via large governmental stations, but their data are not published in real time and the mesh is not dense enough to quickly detect local pollution peaks and analyze their causes. PlanetWatch is a global network of air quality sensors and environmentally-conscious people who help build a dense mesh of sensors to deliver much needed hyperlocal air quality data worldwide. PlanetWatchers buy and deploy air quality sensors outside their homes or carry them while moving in the city or traveling. This approach enables us to quickly deploy low-cost, real-time sensing networks that effectively complement governmental networks. The same goes for indoor air quality monitoring. Planetwatchers can deploy sensors in their homes and generate data which are instrumental to protect their families’ health and to power scientific studies. ## Key features - Activate sensor license - Monitor local air quality - Contribute to global network - Deploy sensors indoors or outdoors - Generate real-time data ## Recent user reviews (10 of 40) All indexed reviews: https://appshunter.io/ios/app/planetwatch/id1570837345/reviews.md ### 1/5 — Overly invasive and better alternatives *2023-04-02* Wants to scan your face and ID to verify you to show you air quality???? ### 1/5 — App mostly useless *2022-08-22* Doesn’t really work functions never complete ### 1/5 — App chrash *2022-08-20* Complete scam, finger weg! ### 1/5 — Nonexistent Customer Service *2022-06-13* I contacted Customer Service for over TWO weeks ( multiple tickets opened ), and nothing. No response at all. None. ### 3/5 — Struggling *2022-05-09* This app is struggling a lot. It is slow, not updating as should do. You have to log in of log out 5 times before you can see your sensors. Also sensors streaming is up and down. For last 2 days gettin really low %. Def needs some work on this. ### 1/5 — Lying sack of crap company *2022-03-31* Join a site to see what I’m talking about. ### 1/5 — Sign in problem *2022-03-19* This app does not recognize username and password. Same user name and password works on website but not on app. Reset email from app never arrives, reset on website possible but app does not recognize username and password. How are we suppose to make this work? Pls help with this problem. Without logging in this app is useless. ### 1/5 — Cant log in, network error code 400! *2022-02-20* So annoying ### 2/5 — Email and password do not save *2022-02-06* Every time you open the application you have to enter your email and password. Most other iOS applications allow you to use face ID to sign into the app so you don’t have to manually type in your username and password every time. Please fix this ### 1/5 — The app does not reflect well on the project *2022-01-26* I feel that PlanetWatch itself is a great project, but it needs an app that is to a higher standard, especially if we’re supposed to trust it with a seed phrase. Face ID doesn’t work, it has never tried to unlock with my face. Every day I have to sign in again because upon initial launch the app is blank. When you sign out, the wallet is supposed to reset and yet even after doing a clean install, it’s still there which is uncomfortable. Finally, why do we need two accounts to use this platform, especially since the emails have to match? You need one for the website and another for the app and explorer. ## Frequently asked questions about PlanetWatch ### What does the PlanetWatch app do?
