How to read the index
Every number is a count of completed answers from each engine's API, with web search on. These are not a record of what every shopper sees in consumer apps, and answers change as models and the web change, so every page is dated.
The order is a count of answers, not a rating. We don't test products, and no brand pays to be listed.
