A private, on-device iPhone speech coach with six practice modes and specific feedback on pacing, fillers, vocabulary and coherence.

Six Practice Modes: Impromptu speaking, defending a topic, three questions, storytelling, elevator pitch and reading aloud, so you can drill the specific format you need.
On-device Coaching: Apple Intelligence runs speech recognition and the coaching language model on the iPhone itself, so a whole session completes in airplane mode with no account.
Specific Delivery Feedback: Every session is scored on pacing, fluency, vocabulary and coherence, and ends with three concrete tips rather than a generic rating.
Privacy by Design: Recordings are never uploaded on any path; the two optional cloud paths send transcript text only and are opt-in.
Habit Tracking: A subtle daily reminder, a visible streak and a two-week progress sparkline keep practice consistent over time.
Optional Enhanced AI Coaching: Pro users can switch on a deeper report generated from transcript text by OpenAI, off by default.
Offline Cloud Fallback: iPhones that cannot run Apple Intelligence can opt into a text-only cloud coach via Sign in with Apple.

Interview Preparation: Rehearse answers to behavioural and technical questions and get feedback on filler words and pacing before the real interview.
Pitch Rehearsal: Practise a 60-second elevator pitch repeatedly and tighten vocabulary and coherence between takes.
Debate and Argumentation Practice: Use the defend-a-topic mode to build the habit of structuring an argument under time pressure.
Accent and Fluency Work for Language Learners: Read aloud daily and track fluency and pacing improvements on the two-week sparkline.
Public Speaking Confidence: Run short impromptu drills on a streak to reduce hesitation before conference talks or presentations.
Privacy-sensitive Practice: Rehearse confidential material — internal pitches, legal or medical scenarios — knowing audio never leaves the device.
