Tekerleme is an Android application by Figen Güngör, designed to improve your diction while providing entertainment. The app features a variety of tongue twisters that you can attempt to read out loud. By tapping the microphone icon, the app records your attempt and provides feedback on whether you pronounced the words correctly or not.

It's important to note that the speech recognition system can be a bit finicky at times, so be sure to enunciate clearly and avoid slurring your words, especially when emphasizing syllables. Additionally, speaking too loudly can cause the system to struggle with recognition.

Overall, Tekerleme is a fun and useful tool for anyone looking to improve their diction or simply pass the time with a fun challenge. Best of all, it's completely free to use.
