Tinder has been getting hotter this summer. The hook-up app, popular for "swipe right" to match or left to reject, had the biggest jump in app store rankings for iPhone over the last 30 days, data from the analytics company SimilarWeb reveals.

The report, compiled by VentureBeat using SimilarWeb's mobile traffic tracking tools, ranks Tinder as the top gainer for iOS apps, just above QR reader for iPhone, Walmart's shopping app and ride-hailing service Lyft. Tinder is now listed at number 69. With this new data, Tinder is estimated to be installed on nearly 3 percent of smartphones in the United States.

As to app engagement, Tinder's users interact with the app for about two minutes spread across eight check-ins each day, on average, according to SimilarWeb data. Tinder, while quiet about its total user base, reported in April that users swipe through 1.6 billion Tinder profiles and 26 million matches are made each day on the app.

Tinder launched in September 2012 and has since faced competition from rival dating apps such as Hot or Not, Hinge and happn. But according to SimilarWeb data, Tinder may still be on the rise. The app experienced the most installs for each monthly data report in 2015 comparatively. Tinder had a nearly 3 percent bump in downloads for May 2015 while Hot or Not had about 2 percent, Hinge had 0.5 percent and happn faced a nearly 0 percent increase.

Tinder faced criticism from users in November after unveiling its plans for a paid model. It now limits the number of swipes a user can make per day on the free version, and the company also charges more to older users for a subscription to Tinder Plus. The app also introduced advertising to the app in April, starting with a campaign from Bud Light's Whatever USA and since rolling out new partnerships such as with the summer movie "Trainwrecked."

While Tinder was the top gainer on iOS, according to SimilarWeb, Instagram ranked as the biggest winner on Android, followed by mobile games Subway Surfers and 8 Ball Pool. Messenger and Snapchat experienced the biggest drop-offs on iOS, and Candy Crush Soda Saga and The Weather Channel faced the highest ranking drops on Android.
