User Friendly APP

Great app!

Easy to use, clean interface, and accurate data. Auto fills locations around you so you don’t have to manually input them yourself. Neat tool!

Straight Forward

This app has a format that is clear and easy to understand. It gives me peace of mind to understand the air quality in my area.

Great but flawed

The good: intuitive access to sensor network, more accuracy than other apps I’ve used, sensor reliability indicators.

The bad: favorites cannot be grouped by location.

The ugly: $10/year subscription to turn on air quality push notifications. Notifications are a basic safety feature in an air quality app, and linking them to a subscription service feels like hostage-taking. I’d gladly pay $30 for a one-time purchase of this app, but signing on to an open ended recurring payment where I’m opted into future price hikes is a hard no.

The guy who invented SaaS should be vilified as one of history’s greatest scoundrels.

Great app, super clean UI!

A great app that fills a valuable niche in a way that few others do quite so well. Very user-friendly, with an excellent UI!
