Astound is a lifestyle app developed by Astound Inc that provides personalized speech exercises to help you speak clearly, confidently, and effectively. The app offers daily speech exercises, including breathing and vocal warm-ups, tailored to your experience level and one of the following goals: speaking tempo, clarity, projection, or pitch.

Astound helps you track your progress by recording your voice daily and providing feedback and guidance on what to listen to. The app offers an extensive library of 100+ easy-to-follow video tutorials, a 30-day challenge to gradually strengthen your voice, and byte-sized practice packs for specific goals, like preparing for an interview, presentation, or an important meeting.

The app also features an audio voice recorder, audio feedback, and analytics on your speaking tempo, pitch modulation, and volume. You can create a playlist with your very own warmup exercises and set reminders to help you build a healthy habit. If you want to get the souped-up version, you can choose from three auto-renewing subscription options that start from $6.49 per month.
