Oompf is an AI speaking coach that helps you become more articulate, confident, and clear in real-life moments like interviews, presentations, meetings, public speaking, and everyday conversations. Practice with Sessions, where you can spin a topic, pick a quick prompt, or create your own speaking scenario and record your answer out loud. Then get feedback on the habits that shape how you sound: structure, conciseness, confidence, energy, filler words, and pace. Train with Role Play scenarios inside Dojo, use Read Out Loud teleprompter practice, and try Beat the Word, a speaking challenge that adds another word with each level. Build steadier speaking habits with quick tools like box breathing, article summaries, tongue twisters, and other speaking drills. Journey gives you guided lessons that build core speaking skills step by step. Leo, your in-app coach, can chat with you in text or voice, help you think through responses, and keep practice feeling personal instead of generic. Add friends and follow your progress in Ranking. Switch between all-time Crown Points and weekly Arena standings, with Everyone and Friends views. Invite friends with your shareable code or public username to earn 30 days of Premium for each of you. When five friends redeem your invite, earn a bonus year on top of your monthly invite rewards. Oompf also includes Word of the Day speaking practice and Home Screen widgets so you can keep your streak going and jump into practice faster. Whether you want to stop rambling, cut filler words, think on your feet, or sound more polished out loud, Oompf gives you a structured way to practice before the real moment.
