The app is so useful when it comes to call recording. Initially, I used another app to record calls on my iPhone, but that app was much more expensive and set limits on the number of calls. That's why, I switched to REKK. The app records everything I discuss with my partners and automatically transcribes the recordings to text. I also like the fact that there're several methods of call recording offered in the app. I just chose the most convenient one and now it seems that it's very easy to create a 3 way call. The app isn't as expensive as its competitors and has more features and no limits.
