# Nebulo vs AQI

The clearest difference is rating: Nebulo at 4.0 against AQI's 3.4. Nebulo also leads on review sentiment (75% vs 42%) and iOS requirement (15.6 vs 17.6). AQI's advantage is update cadence (weekly vs every 4 weeks) and ratings volume (16 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Nebulo holds the better App Store score, 4.0 against 3.4. That said, the two scores are not equally well evidenced: AQI has 16 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 75% of Nebulo's written reviews are positive against 42% of AQI's.

Nebulo ships an update every 4 weeks, AQI weekly. The most recent releases landed on September 30, 2026 and October 20, 2026 respectively.
