Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

AirVisual

Outdoor readings depend on nearby government or crowdsourced monitors, so accuracy varies with local coverage
Indoor measurement needs an IQAir AirVisual monitor bought separately
The app pages do not state what, if anything, costs money

Weatherstack

The free tier allows 100 API calls a month, which is a demo rather than a usable allowance
Historical weather data starts at the Standard plan, $9.99 a month for 50,000 calls
Forecasting is tiered: 7 days from Professional at $49.99 a month and 14 days from Business at $99.99
Multi-language responses and bulk queries need Professional or above
Going past the monthly quota incurs overage charges rather than throttling
