# Magnifying glass vs 气压计

The clearest difference is rating: Magnifying glass at 4.5 against 气压计's 1.0. Magnifying glass also leads on ads (none vs shown) and ratings volume (77 vs 1). 气压计's advantage is update cadence (every 2 weeks vs every 6 weeks). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Magnifying glass sells 2 in-app purchases, starting at $3.99 per 7 days and 气压计 sells 4 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Magnifying glass holds the better App Store score, 4.5 against 1.0. That said, the two scores are not equally well evidenced: Magnifying glass has 77 ratings behind it against 1, so its average is the more settled of the two.

Magnifying glass ships an update every 6 weeks, 气压计 every 2 weeks. The most recent releases landed on November 3, 2026 and November 4, 2026 respectively.
