MapQuest GPS Navigation & Maps is the new No. 1 free iOS app on September 1, 2026, up 5 spots from 6, after TechCrunch on August 31 reported that the 30-year mapping brand refused to rename Lake Ontario as Lake America. The company cited hundreds of thousands of downloads and usage at 50 times normal levels. Sensor Tower had the app 80th in U.S. free navigation a week earlier; ChatGPT fell to 2, and Claude by Anthropic, Google Gemini, and Google are new in the top 10.
Top trending apps on App Store: September 1
MapQuest GPS Navigation & Maps: A GPS and maps client that kept Lake Ontario on the map after a U.S. federal Lake America order. TechCrunch on August 31 said MapQuest reached No. 1 in U.S. Navigation, No. 4 among non-game apps on Monday morning, and No. 8 overall, with Sensor Tower logging 184,000 global and 162,000 U.S. downloads in the week starting August 24 (more than 10 times the prior week). Apple Maps still showed Lake Ontario as of Monday.
ChatGPT: OpenAI's consumer chatbot, yesterday's No. 1, now sits at 2. The title remains a free-chart fixture even as a mapping protest takes the lead.
Vinted: Pre-loved marketplace: A peer-to-peer resale app for clothes and goods. Rank 3 holds versus August 31, in line with back-to-school resale demand rather than a same-day news spike.
ESPN Fantasy Sports & More: ESPN's fantasy suite. Rank 4 after a drop from 2 as U.S. fantasy football season keeps the app on the board.
TikTok Pro - Events: TikTok's events-oriented Pro client. Rank 5 is unchanged from August 31.
Claude by Anthropic: Anthropic's chatbot. New at 6 on the free board, filling space left by dropped entertainment apps.
PineDrama - Short Dramas: A short-form drama player. Rank 7, up from 9, with no separate September 1 premiere cited in major coverage.
Depop - Buy & Sell Clothes: A fashion resale marketplace. Rank 8, up from 10, sitting beside Vinted as a second clothes-trading title.
Google Gemini: Google's Gemini chatbot. New at 9, arriving with the Google app as Maps naming backlash continues.
Google: Google's search and services client. New at 10 on the same free chart that just installed MapQuest at 1.

What changed on App Store since yesterday
MapQuest GPS Navigation & Maps is the day's big mover, 6 to 1 (plus 5). ChatGPT, ESPN Fantasy Sports & More, and TikTok Pro - Events each fell one slot. Vinted held 3. PineDrama rose 9 to 7. Depop rose 10 to 8.
New at 6, 9, and 10: Claude by Anthropic, Google Gemini, and Google. Off the top 10 versus August 31: Netflix Game Controller, ReelShort, and 7 Brew Coffee.
What today's App Store trends reveal
The September 1 free board is a naming fight sitting on top of seasonal fixtures. MapQuest's Lake Ontario stand, documented August 31, is the only story large enough to take rank 1 from ChatGPT. Google Gemini and Google entering 9 and 10 reads as the same Maps backlash showing up as brand search, not as a separate product launch.
Under that spike, the rest of the chart is familiar. ChatGPT and Claude keep two chatbot vendors in the top 6. Vinted and Depop keep resale in two slots. ESPN Fantasy Sports & More is football season. TikTok Pro - Events and PineDrama are entertainment holdovers. Netflix Game Controller, ReelShort, and 7 Brew Coffee are the titles that lost those seats.
A one-day protest download wave can move a 30-year maps brand from Sensor Tower's 80th in U.S. free navigation to App Store Top Free rank 1. ChatGPT at 2 shows the chatbot slot did not vanish. It yielded.
