Krak also offers the ability to share tips with other users of the app, including photos and descriptions of events, offers, favorite restaurants, and other great places to shop. The app includes thousands of reviews of restaurants, bars, and hotels from both Krak and Yelp users.

Other features of Krak include high-resolution maps with various settings, including standard maps, aerial photos, hybrid maps, street photos, and historical photos fromKrak also offers integration with Krak Navigation, which provides offline GPS directions, and the ability to avoid traffic with the 'live traffic' feature.

Krak requests permission to check incoming calls and messages that are not in the user's contact list, so users can see who is calling or texting them. It should be noted that Krak does not read or store any data, but only looks up the number for the user.
