In second place was Uber with 94 million downloads, while Bolt, Didi, Grab and Lyft also made the list.
Considering how the pandemic kept many people confined to their own country or city, the focus on maps and alternative transport apps makes sense.
In ninth place is the train timetable and status checking service Where Is My Train. Despite only being available in India, the company had over 23 million downloads from commuters.
Unsurprisingly, Skyscanner, which ranked 9th in 2020, was pushed off the list.
Booking.com and Airbnb also featured on Apptopia's list of top 10 online travel agency apps for 2021.
