A market is what a buyer compares before choosing: finer than a category, and the unit a competitor arrives in. Every one below holds the incumbents and the week-old challengers in the same list, with the date each turned up.
When apps turned up, and in which market. Counts rather than share: a quarter with three times the arrivals should look three times taller.
No data means we have not measured it yet, not that it is zero. Survival counts only apps that arrived the way the corpus arrived, so an admitted incumbent is in the market and out of that figure. Entry price is the median cheapest paid plan among apps that arrived in the window.
1 market, ordered by arrival rate.
