COMPLAINTS
Most common: Crashes & bugs, 70 of 274 classified 1–2★ reviews.
Google ranks these by how many people found them helpful, which leans towards complaints — so the shares show which problems dominate, not how many users hit them.
Each 1–2★ complaint was assigned one theme by an AI model. A second AI model re-read 100 random labels in September 2026: about 7 in 10 matched its own pick and 9 in 10 were a reasonable reading. Read the order of the leading themes, not exact shares. Classified on 2026-09-16.
