Make the first 35 seconds count.

Research shows first impressions form within seconds, while communication experts like Harvard Catalyst recommend keeping introductions brief and conversational. Ten seconds is rarely enough to say anything memorable, while sixty seconds often feels too long for a first meeting. 35 seconds is our intentionally designed sweet spot. It's enough time to explain who you are, what you do, and what makes you memorable without losing attention. It isn't claimed to be a scientifically perfect number, but a practical framework grounded in how people naturally form first impressions.

No. All audio recording and analysis happens entirely on your device. Your voice recordings never leave your phone. We use Apple's on-device speech recognition and our own local audio analysis. Zero cloud processing.

Fair question. ChatGPT is genuinely good at helping you draft an intro. First35 is built for a different problem: turning that draft into something you can actually deliver in a real moment. You practice out loud instead of just reading, and each take is scored on how you actually sound (pace, steadiness, expressiveness, pause patterns, window-use). All audio analysis happens on-device, so your voice never leaves your phone. Daily streaks and a heatmap help you build a habit, and you can see your delivery improve over time. Think of First35 as your rehearsal space, coach, and scorekeeper.

We use specially tuned AI to generate three curated pitch variants for you based on your answers during onboarding. This is the only step that happens outside your phone. No PII (personally identifiable information) is handed to an AI model. After that, all practice, scoring, voice analysis and feedback is computed locally on your phone.

Yes with Premium — create unlimited intros, each for a different context (interviews, investors, networking, different languages), with independent practice history and streaks. The free plan supports 1 saved intro at a time.

After each practice take, First35 scores you on five metrics: Pace (are you rushing or dragging?), Steadiness (is your volume consistent?), Expressiveness (is your pitch varied or monotone?), Window-use (did you use the full 35 seconds?), and Pause/flow (are your pauses natural?).

First35 requires iOS 17 or later. That includes iPhone XS, XR, SE (2nd gen) and every iPhone released since 2018.

Yes, but only if you want to. You have a choice to export a practice take as an animated voice card with your score overlay. You can download it to your album, or share it directly to social media with pre-written captions designed to get you improvement feedback from your network.
