MapQuest’s mobile app jumped up the App Store charts after the company said it would keep using Lake Ontario rather than adopt Lake America on its maps, according to TechCrunch and a Techmeme summary of MacRumors reporting. TechCrunch reports that MapQuest announced Thursday it would not change the lake’s name, despite President Trump’s executive order directing the U.S. Department of the Interior to update the name in the U.S. geographic naming service. Techmeme, citing MacRumors, also reports that MapQuest refused to change Lake Ontario to Lake America. The ranking impact was immediate enough to put a legacy mapping brand back into the app-store conversation. TechCrunch says MapQuest’s iOS app reached No. 4 on the U.S. App Store’s Top Charts for apps, excluding games, as of Monday morning on the U.S. East Coast. It also became the No. 1 Navigation app in the United States and reached No. 8 overall across apps and games, according to TechCrunch. Techmeme’s MacRumors summary corroborates the No. 4 U.S. App Store ranking. Canada’s chart position is less cleanly aligned across the two items. TechCrunch says MapQuest reached No. 2 overall in Canada’s App Store as of Sunday evening. Techmeme, citing MacRumors, says MapQuest became the top free iPhone app on the App Store in Canada. The difference may reflect chart category or timing, but the provided summaries do not resolve it. MapQuest itself said it received “hundreds of thousands” of new downloads after the decision and that app usage climbed to 50 times normal levels, TechCrunch reports. TechCrunch also cites Sensor Tower data estimating 184,000 global downloads and 162,000 U.S. downloads during the week beginning August 24, with both figures more than 10 times higher than the previous week. In the U.S., daily downloads were up 128% day over day from August 26 to August 30, according to the same report. The company leaned into the attention with a web tool that lets users jokingly rename Lake Ontario and share the result on social media, TechCrunch reports. The outlet says MapQuest offered a similar tool last year after Trump renamed the Gulf of Mexico to the Gulf of America. Other mapping platforms are taking different approaches. TechCrunch reports that Google Maps said Saturday it would comply with the name change because it updates maps based on official government sources, including the Geographic Names Information System in the U.S. Under Google’s approach, users in the U.S. will see the updated name, users in Canada will see Lake Ontario, and users outside both countries will see both names, according to TechCrunch. Apple Maps had not renamed the Great Lake or issued a statement on its plans as of Monday morning, TechCrunch reports. The same report notes that both Apple Maps and Google Maps changed Gulf of Mexico to Gulf of America last year after a similar executive order. Who benefits: MapQuest is the clear near-term beneficiary, with reported App Store gains, higher usage, and third-party download estimates showing a sharp rise. Users who specifically want maps that retain Lake Ontario also have a newly prominent option. Who's exposed: Large map providers are exposed to scrutiny over how they apply official naming sources across regions. TechCrunch reports that Google Maps is complying for U.S. users, while Apple Maps had not stated its plans as of Monday morning.
