The recent major update delivered a positive net impact, driven by a +0.92 star increase in the average iOS rating from 3.31 to 4.23. This upward shift stems from resolving a critical platform compatibility issue where earthquake notifications arrived minutes after seismic events. However, newly introduced subscription prompts for historical data and geographical naming errors on maps present immediate headwinds.
