AQI (Air Quality Index) v5.1

Purelogic Labs

About this app

The AQI app solves the problem of providing real-time air quality and weather information to users worldwide, benefiting those who prioritize environmental health and safety. Compared to alternatives in the Weather category, AQI stands out for its focus on air pollution, but falls short in terms of overall feature set and user ratings. With a moderate download count and mixed user reviews, AQI has room for improvement, but its ad-free model and lack of in-app purchases are notable advantages. As a free app with no permissions required, AQI's simplicity and transparency are significant strengths.

Pros

AQI's ad-free model ensures a seamless user experience without interruptions, making it a great choice for those who value simplicity and ease of use.
The app's lack of in-app purchases and permission requests suggests a commitment to user privacy and transparency, which is rare in the Weather category.
With over 500,000 downloads, AQI has established a moderate level of social proof, indicating a sizable user base and potential for community engagement.
The developer's website and email support suggest a level of accountability and responsiveness to user concerns, which is essential for building trust.
AQI's small size and low Android requirement make it an accessible option for a wide range of devices, including older models and those with limited storage capacity.

Cons

The app's mixed user reviews and average rating of 3.3 suggest that some users may be experiencing issues with accuracy, functionality, or overall performance.
The limited feature set and lack of advanced weather forecasting tools may make AQI less appealing to power users or those who require more detailed information.
Some users may be concerned about the app's data collection practices, despite the lack of permissions, and may wish for more transparency or control over their personal data.
The app's update frequency and responsiveness to user feedback are unclear, which may impact its long-term viability and ability to address user concerns.

Best for: The ideal user for AQI is likely an environmentally conscious individual, aged 25-45, who prioritizes air quality and weather information for personal or professional purposes, such as outdoor enthusiasts, cyclists, or those with respiratory health concerns, and has a moderate level of technical skill to navigate the app's features and settings.

Shalini Pippal

very good app you should try but some things are work on websites that is not good overall really very good app

★★★★

Sajan Stanley

The app is wonderful. The way it relates the city pollution levels to the number of cigarettes smoked in a day or week is genius. that's a big eye opener to normal people like me. Only problem : the widget does not update correctly. it would show a AQI of 50 but when you open it, it will change to 80. so that's not consistent.

★★★

Mohit Negi

see the app is good. the problem is it crashes sometimes. and I tried searching other areas multiple times. it just doesn't search. it auto detects the area based on ur location shows the aqi but if I wanted to search different area aqi through ur search box. it does nothing it doesn't show those areas. even if u put pincode.fix it. Need a lot of improvement, in this app

★★

Piyush Rana

Good effort but the data is inaccurate. In a very fine morning when it was drizzling the app showed AQI of 105 as against the AQI of 33 shown by the Android weather app. Another issue, the widget doesn't work on manual location data. It needs location data permission to work.
